Imaging diagnostics are an essential element in the evaluation of spine trauma. Over the last few decades, the rapid evolution of imaging technology has tremendously changed the assessment and treatment of spinal injuries. Imaging diagnostics utilizing CT and MRI, among others, are helpful in the acute and the chronic settings. Spinal cord and soft-tissue injuries are best evaluated by magnetic resonance imaging, or MRI, whereas computed tomography scanning, or CT scans, best evaluate spinal trauma or spine fracture. The purpose of the article below is to demonstrate the significance of imaging diagnostics in spine trauma.
Cervical Spine Fracture Evaluation
Practice Essentials
Approximately 5-10% of unconscious patients who present to the ED as the result of a motor vehicle accident or fall have a major injury to the cervical spine. Most cervical spine fractures occur predominantly at two levels: one-third of injuries occur at the level of C2, and one-half of injuries occur at the level of C6 or C7. Most fatal cervical spine injuries occur in upper cervical levels, either at craniocervical junction C1 or C2. [1, 2, 3, 4, 5, 6, 7, 8]
Anatomy
The normal anatomy of the cervical spine consists of 7 cervical vertebrae separated by intervertebral disks and joined by a complex network of ligaments. These ligaments keep individual bony elements behaving as a single unit. [7]
View the cervical spine as three distinct columns: anterior, middle, and posterior. The anterior column is composed of the anterior longitudinal ligament and the anterior two-thirds of the vertebral bodies, the annulus fibrosus and the intervertebral disks. The middle column is composed of the posterior longitudinal ligament and the posterior one-third of the vertebral bodies, the annulus, and intervertebral discs. The posterior column contains all of the bony elements formed by the pedicles, transverse processes, articulating facets, laminae, and spinous processes.
The anterior and posterior longitudinal ligaments maintain the structural integrity of the anterior and middle columns. The posterior column is held in alignment by a complex ligamentous system, including the nuchal ligament complex, capsular ligaments, and the ligamenta flava.
If one column is disrupted, other columns may provide sufficient stability to prevent spinal cord injury. If two columns are disrupted, the spine may move as two separate units, increasing the likelihood of spinal cord injury.
The atlas (C1) and the axis (C2) differ markedly from other cervical vertebrae. The atlas has no vertebral body; however, it is composed of a thick anterior arch with two prominent lateral masses and a thin posterior arch. The axis contains the odontoid process that represents fused remnants of the atlas body. The odontoid process is held in tight approximation to the posterior aspect of the anterior arch of C1 by the transverse ligament, which stabilizes the atlantoaxial joint. [9, 7]
Apical, alar and transverse ligaments provide further stabilization by allowing spinal column rotation; this prevents posterior displacement of the dens in relation to the atlas.
In pediatric patients, the spine is more flexible, and therefore, neural damage occurs much earlier than musculoskeletal injury in young patients. Because of this high flexibility, fatal consequences can occur with sometimes even minimal structural damage. Compared to adults, children have a different fulcrum because of a relatively large head, the vertebrae are not completely ossified, and the ligaments are firmly attached to articular bone surfaces that are more horizontal, making the pathophysiology of injury in children different from that in adults. [6, 10]

The neck consists of seven bones, or the cervical vertebrae, which support the head and connect it the body. A cervical fracture is commonly referred to as a broken neck. Cervical spine fractures often occur due to trauma or injury, such as from automobile accidents or slip-and-fall accidents. Imaging diagnostics have advanced to be able to help healthcare professionals diagnose cervical spine health issues.

Evaluation of injury
When a cervical spine injury is suspected, neck movement should be minimized during transport to the treating facility. Ideally, the patients should be transported on a backboard with a semirigid collar, with the neck stabilized on the sides of the head with sandbags or foam blocks taped from side to side (of the board), across the forehead.
If spinal malalignment is identified, place the patient in skeletal traction with tongs as soon as possible (with very few exceptions), even if no evidence of neurologic deficit exists. The specific injury involved and capabilities of the consulting staff guide further management.
Place tongs one finger width above the earlobes in alignment with the external auditory canal. The consultant applies the tongs for traction under close neurologic and radiograph surveillance. Care must be taken while managing the airway in patients with potential cervical spine injuries. Video-assisted intubation should be considered to limit cervical spine motion during the process of securing the airway. [11, 12, 13, 1]
Cervical spine injuries are best classified according to several mechanisms of injury. These include flexion, flexion-rotation, extension, extension-rotation, vertical compression, lateral flexion, and imprecisely understood mechanisms that may result in odontoid fractures and atlanto-occipital dislocation. [1, 14, 4, 5, 15, 7, 16]
Radiographic evaluation is indicated in the following: [2, 2, 17, 18, 15, 19, 20]
Patients who exhibit neurologic deficits consistent with a cord lesion
Patients with an altered sensorium from head injury or intoxication
Patients who complain about neck pain or tenderness
Patients who do not complain about neck pain or tenderness but have significant distracting injuries
A standard trauma series is composed of 5 views: cross-table lateral, swimmer’s, oblique, odontoid, and anteroposterior. Approximately 85-90% of cervical spine injuries are evident in the lateral view, making it the most useful view from a clinical standpoint.
The advent of readily available multidetector computed tomography has supplanted the use of plain radiography at many centers. Recent literature supports CT as more sensitive with lower rates of missed primary and secondary injury. [14]
Thoracic Spinal Trauma Imaging
Computed Tomography
Findings
Thin-section axial CT performed by using a bone algorithm is the single most sensitive means by which to diagnose fractures of the thoracic spine. Routine helical CT scans of the thoracic spine are valuable because multisection CT scanners can generate high-resolution spinal images, even during a primary multisystemic trauma evaluation. [21, 22, 28, 29]
The CT images below display various thoracic spinal traumatic injuries.
Figure 1: Lateral 3-dimensional maximum intensity projection CT scan of multiple upper thoracic and lower cervical spinous process fractures. The force necessary to fracture the spinous processes of the upper thoracic spine may also involve the lower cervical spine.
Figure 2:�Three-dimensional CT scan of complex mid-face fractures including a Le Fort I injury in a patient who had fractures of the upper thoracic and lower cervical spinous processes. Sudden deceleration of the face and skull resulted in severe stress forces on the spinous processes.
Figure 3:�Axial CT scan of a T12 compression fracture demonstrates a fracture line through the anterior body of the T12 (white arrow), posterior displacement of the T12 vertebral endplate (black arrow) into the spinal canal, and a fracture of the left transverse spinous process.
Figure 4:�Axial and sagittal CT images of an acute lower thoracic spine compression fracture. Note the paraspinal hematoma (white arrows) and the slight narrowing of the spinal canal at the level of the compression fracture (double yellow arrows).
Figure 5:�Three-dimensional CT scan of the thoracic spine demonstrates a compression fracture.
Figure 6:�Sagittal CT scan of the thoracic and lumbar spine demonstrates a complete distraction fracture at the L1-2 interspace (arrow).
Figure 7:�Axial CT image of an unstable fracture of the thoracic spine. Note the association of compression of the vertebral body with laminar and pedicle fractures. Injury to the anterior, middle and posterior columns results in an unstable fracture.
Figure 8:�Coronal multiplanar reformatted CT images of an unstable thoracic spinal fracture. The association of both anterior compression and lateral subluxation (arrows) indicates instability.
Figure 9:�Volume maximum intensity projection CT image of the entire thoracic spine demonstrates spinous process fractures of the C7 through T7 vertebra. Although spinous process fractures of the T1 may occur in a manner similar to a clay shoveler’s fracture of the C6 or C7, middle and lower thoracic spinous process fractures most likely occur due to a combination of forward flexion and axial rotation. Note the lack of findings of compression vertebral body fractures.
Figure 10:�Three-dimensional surface CT image of the cervical spine. Note the spinous process fractures of the C6, C7, and T1. CT examination of both the cervical and the thoracic spine was obtained as a single study using a multisection CT scanner. All images were obtained by using a 3-mm reconstruction with 1.5-mm collimation. Scanning times were 0.5 seconds per rotation. These 3-dimensional images were reconstructed by using an independent imaging workstation. In complex cases, reconstructed images are very useful in consultation with treating physicians.
Figure 11:�Scout view image from a spiral CT scan shows a complete subluxation fracture (curved blue lines) of the lower thoracic spine. Such an injury combines lateral displacement with rotational injury (arrow).
Figure 12: Fracture dislocation of the lower thoracic spine. Axial CT image demonstrates the large distance that the lower thoracic spine has been displaced.
Figure 13:�Axial CT myelogram in a patient with a gunshot wound to the thoracic spine. While a fracture is obvious, the injury also resulted in a dural tear with a freely leaking cerebrospinal fluid space (white arrow). The midline fracture of the vertebral body is noted in the lower image (black arrow).
Figure 14:�Axial CT image demonstrates a complex fracture of the T12 with rotation subluxation. Air was introduced into the epidural space during the injury.
Figure 15:�Sagittal multi-planar CT image of a burst fracture following fixation. The image has been cut in the sagittal plane. Surgical repair of unstable thoracic spine fractures, such as this burst fracture, usually involves placement of an interposition graft (double black arrow) together with a lateral plate held in position by screws placed into the vertebral body above and below the injury. A residual fragment of the burst fracture is seen anteriorly (white arrow). The double white arrow illustrates the restored spinal canal.
Figure 16:�Shaded-surface 3-dimensional CT image of a burst fracture following fixation. The image has been cut in the sagittal plane. Surgical repair of unstable thoracic spine fractures, such as this burst fracture, usually involves placement of an interposition graft (double black arrow) together with a lateral plate held in position by screws placed into the vertebral body above and below the injury. A residual fragment of the burst fracture is seen anteriorly (white arrow).
Figure 17: Shaded-surface 3-dimensional CT image of a gunshot wound to the thoracic spine. Although the bullet passed into the interspace, causing a fracture of the vertebral body, the bullet stopped within the spinal canal. Note the outline drawn around the bullet (arrow).
Figure 18:�Shaded-surface 3-dimensional CT scan of a gunshot wound to the thoracic spine. In other cases, the bullet may enter the spinal canal superior to the final position in the canal. The passage of the bullet within the spinal canal (yellow arrow) destroys the spinal cord and also may result in a fracture of the vertebral body. Note that the bullet has been darkened (blue arrow).
Figure 19:�Axial CT image in a man with known pulmonary tuberculosis and back pain. Note the left-sided paraspinal abscess (arrow).
Figure 20:�Sagittal shaded-surface 3-dimensional reconstruction CT scan of the lower thoracic spine. The spinal image has been cut in the midsagittal plane to demonstrate posterior displacement of the thoracic spinal vertebral body (arrow) and downward displacement of the superior endplate. Note the general wedge shape of the vertebral body.
Because of its superior contrast definition and the absence of superimposed structures, good-quality CT imaging depicts more thoracic spinal injuries than do conventional radiographic studies. However, the percentage of clinically important fractures that are seen on CT scans but not on radiographs is lower with thoracic than with cervical spinal fractures. Most of the fractures missed on radiographs were spinous process fractures, transverse processes fractures, and fractures in large patients. Because axial CT is performed with patients in a neutral position, bony distraction of the fracture fragments and subluxations of the spinal articulations may not be as significant on CT images as on they are on acute trauma-series radiographs. [22, 25, 28, 29, 30, 31, 32]
The level of a burst fracture and the percentage of spinal canal stenosis have been correlated with associated neurologic deficits. A significant correlation exists between neurologic deficit and the percentage of spinal canal stenosis. The higher the level of injury, the greater the probability of neurologic deficit. This association may be related to the smaller canal diameter in the upper thoracic spine. The severity of neurologic deficit cannot be predicted.
In patients with Chance-type fractures, CT scans often show a burst-type fracture with posterior cortex buckling or retropulsion, and serial transaxial CT images often show a gradual loss of definition of the pedicles. [23]
The thoracic spine, located between the cervical and lumbar vertebrae, consists of 12 vertebrae levels. Thoracic spinal trauma, including spinal cord injuries along the middle of the spine, can generally be severe, however, with early treatment, long-term prognosis is good. Therefore, imaging diagnostics for thoracic spinal trauma are essential. Many healthcare professionals can provide patients with these services.
Dr. Alex Jimenez D.C., C.C.S.T.
�
Degree of Confidence
The confidence level for the diagnosis of a thoracic spinal fracture with 2-mm axial sections (possible with a multisection CT unit) is greater than 98% and reportedly 99%.
Because axial CT is performed with the patient in a neutral position, a bony distraction of the fracture fragments and subluxations of the spinal articulations may not be as significant on CT images as on acute trauma-series radiographs.
False Positives/Negatives
False-positive results may occur in patients with a Schmorl node, which is a chronic internal herniation of the vertebral disk into the thoracic vertebral body endplate and failure of the fusion of the anterior vertebral endplate epiphysis, resulting in a limbus vertebra. False-negative CT studies may occur in chronic stress injuries and severe generalized osteoporotic endplate fractures.
It has been reported that among trauma patients who had a chest and/or abdominal CT, fractures of the thoracic spine are frequently underreported. Sagittal reformats of the spine obtained from thin sections, and morphometric analysis using electronic calipers help to identify fractures that might otherwise not be identified. [25]
In conclusion, imaging diagnostics of�spinal trauma or spine fracture are essential towards the assessment and treatment of patients. Magnetic resonance imaging, or MRI, is helpful in the evaluation of spinal cord and soft-tissue injuries whereas computed tomography scanning, or CT scans, is helpful in the evaluation of spinal trauma or spine fracture. The understanding of imaging technology has tremendously enhanced advances in treatment.� The scope of our information is limited to chiropractic, spinal injuries, and conditions.

Additional Topics: Acute Back Pain
Back pain�is one of the most prevalent causes of disability and missed days at work worldwide. Back pain attributes to the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience back pain at least once throughout their life. The spine is a complex structure made up of bones, joints, ligaments, and muscles, among other soft tissues. Because of this, injuries and/or aggravated conditions, such as�herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
Hangman’s Fx aka traumatic spondylolisthesis of C2 with a fracture of pars interarticularis or pedicles (unstable)
MVA is the most common cause
Mechanism: acute hyperextension of upper C/S similar to judicial hanging (never actually seen and most deaths are due to asphyxiation)
Secondary flexion may tear PLL and disc
Associated injuries: 30% have other c-spine fx especially Extension teardrop at C2 or C3 due to avulsion by ALL
Cord paralysis may only present in 25% due to bony fragments dissociation and canal widening
Hangman fx and extension teardrop
Cervical degeneration and previous fusion is a key predisposing factor due to the lack of mobility and suppleness, rendering C/S easy to fracture
Imaging: initial x-radiography then CT that helps to delineate another injury such as facet/pedicle Fx further. MRI may help if complicated by Vertebral A. damage
Management: if type 1 injury then closed reduction and rigid collar for 4-6 weeks, halo bracing if type 2 (>3-5mm displacement) Fx/instability, anterior or posterior spinal fusion at C2-3 if type 3 Fx (>5-mm displacement)
Extension teardrop Fx (stable) potentially unstable if put in extension
Avulsion of an inferior anterior body by ALL. More seen in elderly with superimposed C/S spondylosis
Key radiography: a smaller anterior-inferior body corner, no disruption of ligamentous alignment. Typically at C2 or C3 due to sudden hyperextension and ALL avulsion
Complication: central cord syndrome (m/c incomplete cord injury) esp. in superimposed spondylosis and canal stenosis by the laxity of ligamentum flavum and osteophytes
Management: hard collar isolation
Vertical (axial) Compression Injury
Jefferson Fx (named after British neurosurgeon who defined it) (unstable but neurologically intact Fx) 7% of all C/S injuries. Stability is dependent if the transverse ligament is intact or torn, which can be noted by overhanging of C1 lateral masses over C2 >5-mm combined (left image)
Mechanism: C1 compression (e.g., diving into shallow waters) causing burst Fx-classically 4-parts of the anterior and posterior arch of C1. Variations exist.
Complications: 50% show other C/S Fx, 40% show Odontoid C2 Fx esp. if extension and axial loading occur
Imaging: x-radiography followed by CT scanning to evaluate subaxial injury and complexity of C1 injury. Note Jefferson Fx with pillar and transverse foramina fx requiring posterior occipital-cervical fusion (below right image).
Management: rigid collar immobilization if the transverse ligament is intact. Halo brace or fusion if the transverse ligament is ruptured
Cervical Injuries With Variable Mechanisms of Trauma
Odontoid process fractures:
These occur�with a variety of mechanisms, flexion, extension, lateral flexion. Elderly with superimposed spondylosis are at higher risk.
Anderson & D’Alonzo classification (below). Type 2 is the most common and most unstable. Type 3 has the best chance of healing d/t more massive bleed into C2 body and better healing potential.
Imaging: x-radiography can miss some Fx. CT scanning is essential.
On x-radiography note tilting of the Dens on lateral and APOM views. CT will reveal the injury and classify it.
Complications: cord injury, non-union
CT scanning: type 2 odontoid fracture (unstable)
Management: type 1 (alar ligament avulsion) most stable�observed and treated with rigid collar.
In young patients, Halo brace is used to treat type 2
Older patients do not tolerate Halo
Operative C1-2 fusion if unstable is Dx and cord signs or other complicating factors are present
Normal Radiographic Variants & Anomalies Simulating Pathology
Pediatric spine appears different especially in children younger than 10-years old.
Normal variations; ADI 5-mm and may increase or decrease on flexed/extended views by 1-2-mm
C2-3 may appear as pseudo-subluxation due to normal ligamentous laxity in children (below arrow)
Pediatric vertebral bodies usually are narrower and anteriorly wedged due to the presence of cartilaginous tissue
APOM view appears different in children, and some asymmetry of C1 articular masses is normal (below top image) and should not be confused with Jefferson Fx
In adults, any asymmetry or “overhanging” of C1 articular masses is pathological and may indicate Jefferson fx
Standard ossification centers of the Atlas synchondrosis in children should not be mistaken for fractures
Persistent ossiculum terminal of Bergman is a typical variant/anomaly of tenacious un-united ossification center and should not be confused with type odontoid fx
Os odontoideum
Un-united growth center that currently considered as an un-noticed injury that disturbed normal growth in a child younger than 5-years-old
It may be a cause of C1-2 instability and should be evaluated with flexed and extended cervical views
Should not be confused with type 2 Dens fracture because it typically more demonstrates greater mineralization of bone
Incomplete bilateral agenesis of the C1 posterior arch
Anomalous closure of C1 posterior arch
Should not be confused with a fracture
However, local or cord symptoms may develop after trauma in some cases
Relatively rare anomaly developing due to failed chondrogenesis and ossification of posterior ossification centers of the Atlas
Patients with Down syndrome may suffer from increased ligamentous laxity and other abnormalities
Increased risk of subluxation at C1-2
Burst Fx (unstable) 2-columns are damaged
Mechanism: axial loading with frequent flexion after falls and MVAs
The thoracolumbar region is the most vulnerable due to the increased fulcrum of motion
Key radiography: acute compression fracture and�collapse of body height, retropulsion of posterior body and acute kyphotic deformity on the lateral view
On the frontal view: interpedicular widening (below yellow arrow), regional soft tissue swelling (below green arrow)
Imaging: x-radiography should be followed by CT scanning w/o contrast
MRI if neurologically unstable due to cord or conus injury
Complications: cord damage by acutely retropulsed bone fragments
Management: non-operative if neurologically intact and <50% body retropulsed with minimal kyphosis
Operative (fusion) if 50% or more body retropulsed, laminar/pedicle Fx, neuro compromised
18-Year Old Female Following Trampoline Accident
AP & lateral L/S views
Note acute compression fracture, a vertebral body extending to posterior elements
Widening of the inter-spinous distance between T11-T12 (below arrow)
Radiolucent fracture line is seen through the T12 body on the AP projection
CT scanning was performed
Sagittal reconstructed Thoracic and Lumbar CT slices in bone window
Note acute compression fracture, the T12 body extending into pedicle and lamin
Dx: Chance fracture of T12
MR imaging was performed
T2 Wl sagittal MRI
Findings: acute compression fracture T12 body extending to posterior elements causing rapture of interspinous and flavum ligaments
Mild compression of the distal cord above the conus is noted with a minimal signal abnormality
Dx: Chance fracture
Chance Fx aka (Seatbelt Fx) – is a flexion-distraction injury (unstable)
M/C in lower thoracic-upper lumbar
All 3-columns fail: column 3 torn by distraction, columns 1 and 2 fail on compression (Denis classification)
Causes: MVA, falls
Imaging: initial x-radiography should be followed by CT scanning w/o contrast to assess bone fragments retropulsion/canal compression. MRI may help to evaluate potential cord damage and ligaments tearing
Management: non-operative immobilization if neuro intact
Cranio-cervical and upper cervical stability is dependent on transverse, superior and inferior bands of the C1-C2 ligament, alar ligaments, along with a few other ligaments
Cervical Trauma
The C/S is vulnerable to injury. Why?
Stability has been sacrificed for greater mobility
Cervical vertebrae are small and interrupted by multiple foraminae
The head is disproportionately heavy and acts as an abnormal lever especially when forces act against a rigid torso
Additionally, C/S is prone to degeneration which makes it more vulnerable to trauma
In young children, ligaments are more luxed vs. disproportionately large head size
In children, the fulcrum of movement is at C2/3 thus making injuries more common in the upper C/S and craniocervical junction. In children, S.C.I.W.O.R.A. may occur when no evidence of fracture present
In adults, the fulcrum of movement is at C5/6 thus making lower C/S more vulnerable to trauma especially during extremes of flexion
Cervical Trauma categorized according to mechanisms of injury (Harris & Mirvis classification)
Hyperflexion Injury: Stable vs. Unstable
Flexion teardrop Fx (most severe fracture, unstable)
Begins with x-radiography especially in cases with no significant neurological compromise
Clear neutral lateral view first
If x-radiography is unrewarding but high probability of severe trauma and neurological deficit present, CT scanning w/o contrast is required
Consider CT scanning in patients with pre-existing changes: advance spondylosis, DISH, AS, RA, post-surgical spine, congenital abnormalities (Klippel-Feil syndrome, etc.)
Vertical compression:
Jefferson aka burst Atlas Fx (unstable especially if the Transverse ligament is torn, cord paralysis in 20-30% only)
Why? Due to fragments dissociation and canal widening
Burst Fx of the Thoracic or Lumbar spine (unstable, cord paralysis may occur)
How to Assess Spinal Radiographs in Trauma Cases:
Construct 5-lines on the lateral view
Note if facets are well-aligned and symmetrical
Ensure symmetry of the disc height
Note any widening or fanning of the inter-spinous distance
Carefully examine prevertebral soft tissues
Evaluate atlanto-dental interval (ADI)
In cases of trauma, evaluate and clear neutral lateral first
Do not perform flexed and extended views in acute cases before x-rays or CT scanning exclude significant instability
Pay extra attention to prevertebral soft tissues
If thicker than normal limits, consider severe post-traumatic bleed
Subtle asymmetry and widening of posterior disc height and facets with inter-spinous fanning may be a key feature of significant tearing of posterior ligaments
Hyperflexion Injuries (M/C Mechanism)
More frequent in sub-axial C/S C-3-C7)
Unstable injuries:
Flexion teardrop fracture (M/C C5 & C6) v. unstable
Key rad features:
Large “teardrop” triangular anterior body fragment
Fanning of the SPs, posterior disc and facet widening indicating tearing of major spinal ligaments and instability
A posterior shift of the vertebral body fracture suggests direct anterior cord/vessels compression
Bulging prevertebral soft tissue >20-mm at C6-7
80% of cases may be paralyzed on the spot or develop significant paralysis soon after
Acute Neck Trauma. What are the vital radiographic features? What is the diagnosis?
Imaging diagnostics of the spine consist from radiographies to computed tomography scanning, or CT scans, in which CT is utilized in conjunction with myelography and most recently with magnetic resonance imaging, or MRI. These imaging diagnostics are being used to determine the presence of abnormalities of the spine, scoliosis, spondylolysis and spondylolisthesis. The following article describes various imaging modalities and their application in the evaluation of common spinal disorders described.
Achondroplasia
Achondroplasia is the most common cause of rhizomelic (root/proximal) short-limb dwarfism. Patients are of normal intelligence.�
It shows multiple distinct radiographic abnormalities affecting long bones, pelvis, skull, and hands.
Vertebral column changes may present with significant clinical and neurological abnormalities.�
Achondroplasia is an autosomal dominant disorder with about 80% of cases from a random new mutation. Advanced paternal age is often linked. Achondroplasia results from a mutation in the fibroblast growth factor gene (FGFR3) which causes abnormal cartilage formation.
All bones formed by endochondral ossification are affected.
Bones that form by intra-membranous ossification are not normal.
Thus, skull vault, iliac wings develop normally vs. the base of the skull, some facial bones, vertebral column, and most tubular bones are abnormal.
�
Dx: is usually made at birth with many features becoming apparent during the first few years of life.
Radiography plays an important part of clinical diagnosis.
Typical features include: shortening and widening of tubular bones, metaphyseal flaring, Trident hand with short, broad metacarpals and proximal and middle phalanges. Longer Fibular, Tibial bowing, markedly short humeri often with dislocated Radial head and elbow flexion deformity.
Spine: characteristic narrowing of L1-L5 interpedicular distance on AP views. Lateral view shows shortening of pedicles and vertebral bodies, �bullet shaped vertebrae� can be a characteristic feature. Early degenerative changes and canal narrowing occur. The horizontal sacral inclination is an important feature.
Pelvis is broad and short with characteristic �champagne glass� pelvis appearance.
Femoral heads are hypoplastic, but hip arthrosis is normally not observed even in older patients likely due to reduced leverage and lightweight (50kg) of patients.
Management of Achondroplasia
Recombinant human growth hormone (GH)�is currently being used to augment the height of patients with achondroplasia.
Most complications of Achondroplasia are related to the spine: vertebral canal stenosis, thoracolumbar kyphosis, narrowed foramen magnum and others.
Laminectomy extending to pedicles/lateral recess with foraminotomies and discectomies can be performed.
Cervical manipulations are contraindicated.
Imaging diagnostics play a fundamental role in the diagnosis the of scoliosis, an abnormality of the spine which is believed to occur due to an underlying health issue, although most cases of scoliosis are idiopathic. More over, radiographies, CT scans, and MRI, among others, can help monitor the changes of the deformity of the spine associated with this spinal manifestation. Chiropractors can provide imaging diagnostics to patients with scoliosis before proceeding with treatment.�
Dr. Alex Jimenez D.C., C.C.S.T.
�
Scoliosis
Scoliosis is defined as the abnormal lateral curvature of the spine >10-degree when examined by Cobb�s method of mensuration.
Scoliosis can be described as postural and structural.
Postural scoliosis is not fixed and can be improved by lateral flexion to the side of the convexity.
Structural scoliosis has multiple causes ranging from: ? Idiopathic (>80%) ? Congenital (wedge or hemivertebra, blocked vertebra, Marfan syndrome, skeletal dysplasias) ? Neuropathic (neurofibromatosis, neurological conditions like tethered cord, spinal dysraphism, etc.) ? Scoliosis d/t Spinal neoplasms ? Post-traumatic etc.
Idiopathic scoliosis is the most common type (>80%).
Idiopathic scoliosis can be of 3-types ( infantile, juvenile, adolescent).
Idiopathic adolescent scoliosis if patients >10y.o.
Infantile scoliosis if <3 y.o. M>F.
Juvenile scoliosis if >3 but <10-y.o.
Idiopathic Adolescent scoliosis is the most common with F:M 7:1 (adolescent girls are at particular risk).
Etiology: unknown thought to be the result of some disturbance of proprioceptive control of the spine and spinal musculature, other hypotheses exist.
Most seen in the thoracic region and most commonly convex to the right.
Dx: full spine radiography with gonadal and breast shielding (preferably PA views to protect breast tissue).
� Curves that are 50-degrees or greater and rapidly progressing will require operative intervention to prevent severe deformity of the thorax & ribs leading to cardiopulmonary abnormalities. � �? If curvature is < 20-degree, no treatment is required (observation). � �? For curves that are >20-40-degrees bracing may be used (orthosis).
Milwaukee (metal) brace (left).
Boston brace polypropylene lined with polyethylene (right) often preferred because it can be worn under clothing.
Bracing wearing is required for 24-hours for the duration of the treatment.
Note Cobb�s method of mensuration to record spinal curvature. It has some limitations: 2D imaging, not able to estimate rotation, etc.
Cobb�s method is still a standard evaluation performed in Scoliosis studies.
Nash-Moe method: determines pedicle rotation in scoliosis.
Risser index is used to estimate spinal skeletal maturity.
Iliac growth apophysis appears at ASIS (F- 14, M-16) and progresses medially and expected to be closed in 2-3-years (Risser 5).
Scoliosis progression ends at Risser 4 in females & Risser 5 in males.
During radiographic evaluation of scoliosis, it is crucial to report if Risser growth apophysis remains open or closed.
Spondylolysis and spondylolisthesis are health issues which can result in back pain. Spondylolysis is believed to be caused by repeated microtrauma leading to stress fractures in the pars interarticularis. Patients with bilateral pars defects can develop spondylolisthesis, where the degree of slippage of the adjacent vertebrae can progress gradually over time. Patients with suspected spondylolysis and spondylolisthesis may initially be evaluated with pain radiography. Chiropractic care can also help provide imaging diagnostics for these health issues.
Dr. Alex Jimenez D.C., C.C.S.T.

Spondylolysis & Spondylolisthesis
Spondylolysis defect in pars interarticularis or osseous bridge between superior and inferior articular processes.
Pathology stress fracture of the pars, believed to be after repeated microtrauma on extensions Men > Women, affects 5% of the general population especially in athletic adolescents.
Clinically postulated that adolescent back pain cases may be related to this process.
Typically spondylolysis remains asymptomatic.
Spondylolysis can be present with or w/o spondylolisthesis.
Spondylolysis is found in 90% at L5 with the remaining 10% in L4.
Can be uni or bilateral.
In 65%�of�cases, spondylolysis is associated with spondylolisthesis.
Radiographic Features: break in the Scotty dog collar around the neck on oblique lumbar views.
Radiography has low sensitivity compared to SPECT. SPECT is associated with ionizing radiation, and MRI is currently a preferred method of imaging diagnosis.
MRI can help to show reactive marrow edema next to pars defect or w/o defect so-called pending or potential to develop spondylolysis.
Types of Spondylolisthesis
Type 1 – Dysplastic, rare and found in congenital dysplastic malformation of the sacrum allowing anterior displacement of L5 on S1. Often no pars defect.
Type 2 – Isthmic, most common, often the result of a stress fracture.
Type 3 – Degenerative from the remodeling of articular processes.
Type 4 – Traumatic in an acute posterior arch fracture.
Type 5 – Pathologic due to bone disease locally or generalized.
Grading of spondylolisthesis is based on the Myereding Classification. This classification refers to the overhanging part of the superior body in relation to anterior-posterior part of the inferior body.
Grade 1 – 0-25% anterior slip
Grade 2 – 26-50%
Grade 3 – 51%-75%
Grade 4 – 76-100%
Grade 5 – >100% spondyloptosis
Note degenerative spondylolisthesis at L4 and retrolisthesis at L2, L3.
This abnormality develops due to degeneration of facets and disc with decreased local stability.
Rarely progresses beyond Grade 2.
Must be recognized in the imaging report.
Contributes to vertebral canal stenosis.
Canal stenosis is better delineated by cross-sectional imaging.
The inverted Napoleon hat sign -�seen on the frontal lumbar/pelvic radiographs at L5-S1.
Represents bilateral spondylolysis with marked anterolisthesis of L5 on S1 often with spondyloptosis and marked exaggeration of the normal lordosis.
Spondylolysis resulting in this degree of spondylolisthesis is more often congenital and/or traumatic in origin and less often degenerative.
The “brim” of the hat is formed by the downward rotation of the transverse processes, and the “dome” of the hat is formed by the body of L5.

Additional Topics: Acute Back Pain
Back pain�is one of the most prevalent causes of disability and missed days at work worldwide. Back pain attributes to the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience back pain at least once throughout their life. The spine is a complex structure made up of bones, joints, ligaments, and muscles, among other soft tissues. Because of this, injuries and/or aggravated conditions, such as�herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
Most people don�t even think about visiting a chiropractor until they�ve sustained an injury or need a quick adjustment to help ease the pain. They typically see it as a treatment for injuries or conditions that they�ve already endured, not as a preventative health care option. And while chiropractic care is an exceptional way to treat existing conditions and injuries, that is only half of the picture. It is also a viable health care approach that is effective in improving overall wellness. There are some very compelling reasons to incorporate chiropractic into your everyday life. Chiropractic can:
Help lower your risk of injury
When the spine is out of alignment, it can put stress on other parts of the body including ligaments and joints. Regular chiropractic care helps keep the spine aligned thus reducing your risk of injury.
Elevate your mood
Chiropractic treatment can help to balance your hormones. It increases the feel-good hormone dopamine while decreasing the stress hormone cortisol. It makes it an excellent drug-free option for patients who suffer from anxiety, depression, or mood swings. As part of your treatment, your chiropractor may also recommend dietary and lifestyle changes that can help even more.
Makes you feel more energetic
When your spine is out of alignment, your entire body suffers. You can feel stiff, sore, and fatigues. Most patients report feeling invigorated after their treatment. They can move more naturally and have much more energy. Part of this is due to the effect the treatment has on the body as well as the hormones that are released that provide a boost in your mood.
Help you sleep better
More than 60 percent of people in the United States, both children, and adults report having problems with sleep. Studies show that chiropractic can help with insomnia allowing you to get better, more restful, and more beneficial sleep.
The combination of pain alleviation, increased flexibility, and overall wellness, as well as stress relieving properties, allow your body and mind to relax so that you can fall asleep easier and stay asleep. Incorporating chiropractic care into your everyday routine can help you get a better night�s sleep.
Strengthen your immune system
Studies show that patients who receive regular chiropractic care have a significantly stronger immune system than patients who don�t see a chiropractor. One of the most significant studies to date that explored the connection between regular chiropractic care and a healthy immune system conducted by Dr. Ronald Pero, Ph. D. of New York�s Preventive Medicine Institute where he was the chief of cancer research. He was also a professor of medicine at New York University. The study, which spanned several years, found that patients who received chiropractic care on a regular basis had a 200 percent greater immune competence than non-chiropractic patients.
Manage your pain
Chronic pain, as well as pain from injuries or certain conditions, respond very well to regular chiropractic care. Any discomfort can negatively impact your quality of life, but pain medications can have unpleasant side effects that can be debilitating. It doesn�t help that many pain medications are highly addictive.
Treatments offer a natural remedy for pain that is medication free. What�s more, regularly scheduled therapies work to fix the cause of the problem so that the issue gets permanently resolved.
Make you feel better without medication
Chiropractic treatments are non-invasive and drug-free. It uses the body�s healing properties to address issues naturally and achieve results. It is low risk and very useful, treating the cause of problems, not just the symptoms the way pain medication does.
When you look at all of the benefits of regular chiropractic care and realize that those results can be achieved naturally, it�s easy to see why more people are incorporating it into their health care routines.
While computed tomography scanning, or CT scans, of the cervical spine are frequently utilized to help diagnose neck injuries, simple radiographs are still commonly performed for patients who have experienced minor cervical spine injuries with moderate neck pain, such as those who have suffered a slip-and-fall accident. Imaging diagnostic assessments may reveal underlying injuries and/or aggravated conditions to be more severe than the nature of the trauma. The purpose of the article is to demonstrate the significance of cervical spine radiographs in the trauma patient.�
Abstract
Significant cervical spine injury is very unlikely in a case of trauma if the patient has normal mental status (including no drug or alcohol use) and no neck pain, no tenderness on neck palpation, no neurologic signs or symptoms referable to the neck (such as numbness or weakness in the extremities), no other distracting injury and no history of loss of consciousness. Views required to radiographically exclude a cervical spine fracture include a posteroanterior view, a lateral view and an odontoid view. The lateral view must include all seven cervical vertebrae as well as the C7-T1 interspace, allowing visualization of the alignment of C7 and T1. The most common reason for a missed cervical spine injury is a cervical spine radiographic series that is technically inadequate. The �SCIWORA� syndrome (spinal cord injury without radiographic abnormality) is common in children. Once an injury to the spinal cord is diagnosed, methylprednisolone should be administered as soon as possible in an attempt to limit neurologic injury.
Radiographs continue to be used as a first-line imaging diagnostic assessment modality in the evaluation of patients with suspected cervical spine injuries. The aim of cervical spine radiographs is to confirm the presence of a health issue in the complex structures of the neck and define its extent, particularly with respect to instability. Multiple views may generally be necessary to provide optimal visualization.

Introduction
Although cervical spine radiographs are almost routine in many emergency departments, not all trauma patients with a significant injury must have radiographs, even if they arrive at the emergency department on a backboard and wearing a cervical collar. This article reviews the proper use of cervical spine radiographs in the trauma patient.
Low-risk criteria have been defined that can be used to exclude cervical spine fractures, based on the patient’s history and physical examination.1�6 Patients who meet these criteria (Table 1) do not require radiographs to rule out cervical fractures. However, the criteria apply only to adults and to patients without mental status changes, including drug or alcohol intoxication. Although studies suggest that these criteria may also be used in the management of verbal children,7�9 caution is in order, since the study series are small, and the ability of children to complain about pain or sensory changes is variable. An 18-year-old patient can give a more reliable history than a five-year-old child.
Some concern has been expressed about case reports suggesting that �occult� cervical spine fractures will be missed if asymptomatic trauma patients do not undergo radiography of the cervical spine.10 On review, however, most of the reported cases did not meet the low-risk criteria in Table 1. Attention to these criteria can substantially reduce the use of cervical spine radiographs.
Cervical Spine Series and Computed Tomography
Once the decision is made to proceed with a radiographic evaluation, the proper views must be obtained. The single portable cross-table lateral radiograph, which is sometimes obtained in the trauma room, should be abandoned. This view is insufficient to exclude a cervical spine fracture and frequently must be repeated in the radiographic department.11,12 The patient’s neck should remain immobilized until a full cervical spine series can be obtained in the radiographic department. Initial films may be taken through the cervical collar, which is generally radiolucent. An adequate cervical spine series includes three views: a true lateral view, which must include all seven cervical vertebrae as well as the C7-T1 junction, an anteroposterior view and an open-mouth odontoid view.13
If no arm injury is present, traction on the arms may facilitate visualization of all seven cervical vertebrae on the lateral film. If all seven vertebrae and the C7-T1 junction are not visible, a swimmer’s view, taken with one arm extended over the head, may allow adequate visualization of the cervical spine. Any film series that does not include these three views and that does not visualize all seven cervical vertebrae and the junction of C7-T1 is inadequate. The patient should be maintained in cervical immobilization, and plain films should be repeated or computed tomographic (CT) scans obtained until all vertebrae are clearly visible. The importance of obtaining all of these views and visualizing all of the vertebrae cannot be overemphasized. While some missed cervical fractures, subluxations and dislocations are the result of film misinterpretation, the most frequent cause of overlooked injury is an inadequate film series.14,15
In addition to the views listed above, some authors suggest adding two lateral oblique views.16,17 Others would obtain these views only if there is a question of a fracture on the other three films or if the films are inadequate because the cervicothoracic junction is not visualized.18 The decision to take oblique views is best made by the clinician and the radiologist who will be reviewing the films.
Besides identifying fractures, plain radiographs can also be useful in identifying ligamentous injuries. These injuries frequently present as a malalignment of the cervical vertebrae on lateral views. Unfortunately, not all ligamentous injuries are obvious. If there is a question of ligamentous injury (focal neck pain and minimal malalignment of the lateral cervical x-ray [meeting the criteria in Table 2]) and the cervical films show no evidence of instability or fracture, flexion-extension views should be obtained.17,19 These radiographs should only be obtained in conscious patients who are able to cooperate. Only active motion should be allowed, with the patient limiting the motion of the neck based on the occurrence of pain. Under no circumstance should cervical spine flexion and extension be forced, since force may result in cord injury.
Although they may be considered adequate to rule out a fracture, cervical spine radiographs have limitations. Up to 20 percent11,20,21 of fractures are missed on plain radiographs. If there is any question of an abnormality on the plain radiograph or if the patient has neck pain that seems to be disproportionate to the findings on plain films, a CT scan of the area in question should be obtained. The CT is excellent for identifying fractures, but its ability to show ligamentous injuries is limited.22 Occasionally, plain film tomography may be in order if there is a concern about a type II dens fracture (Figure 1).
While some studies have used magnetic resonance imaging (MRI) as an adjunct to plain films and CT scanning,23,24 the lack of wide availability and the relatively prolonged time required for MRI scanning limits its usefulness in the acute setting. Another constraint is that resuscitation equipment with metal parts may not be able to function properly within the magnetic field generated by the MRI.
Cervical Spine Radiography
Figure 2 summarizes the approach to reading cervical spine radiographs.
Lateral View
Alignment of the vertebrae on the lateral film is the first aspect to note (Figure 3). The anterior margin of the vertebral bodies, the posterior margin of the vertebral bodies, the spinolaminar line and the tips of the spinous processes (C2-C7) should all be aligned. Any malalignment (Figures 4 and 5) should be considered evidence of ligamentous injury or occult fracture, and cervical spine immobilization should be maintained until a definitive diagnosis is made.
Confusion can sometimes result from pseudosubluxation, a physiologic misalignment that is due to ligamentous laxity, which can occur at the C2-C3 level and, less commonly, at the C3-C4 level. While pseudosubluxation usually occurs in children, it also may occur in adults. If the degree of subluxation is within the normal limits listed in Table 2 and the neck is not tender at that level, flexion-extension views may clarify the situation. Pseudosubluxation should disappear with an extension view. However, flexion-extension views should not be obtained until the entire cervical spine is otherwise cleared radiographically.
After ensuring that the alignment is correct, the spinous processes are examined to be sure that there is no widening of the space between them. If widening is present, a ligamentous injury or fracture should be considered. In addition, if angulation is more than 11 degrees at any level of the cervical spine, a ligamentous injury or fracture should be assumed. The spinal canal (Figure 2) should be more than 13 mm wide on the lateral view. Anything less than this suggests that spinal cord compromise may be impending.
Next, the predental space�the space between the odontoid process and the anterior portion of the ring of C1 (Figure 2)�is examined. This space should be less than 3 mm in adults and less than 4 mm in children (Table 2). An increase in this space is presumptive evidence of a fracture of C1 or of the odontoid process, although it may also represent ligamentous injury at this level. If a fracture is not found on plain radiographs, a CT scan should be obtained for further investigation. The bony structures of the neck should be examined, with particular attention to the vertebral bodies and spinous processes.
The retropharyngeal space (Figure 2) is now examined. The classic advice is that an enlarged retropharyngeal space (Table 2) indicates a spinous fracture. However, the normal and abnormal ranges overlap significantly.25 Retropharyngeal soft tissue swelling (more than 6 mm at C2, more than 22 mm at C6) is highly specific for a fracture but is not very sensitive.26 Soft tissue swelling in symptomatic patients should be considered an indication for further radiographic evaluation. Finally, the craniocervical relationship is checked.
Odontoid View
The dens is next examined for fractures. Artifacts may give the appearance of a fracture (either longitudinal or horizontal) through the dens. These artifacts are often radiographic lines caused by the teeth overlying the dens. However, fractures of the dens are unlikely to be longitudinally oriented. If there is any question of a fracture, the view should be repeated to try to get the teeth out of the field. If it is not possible to exclude a fracture of the dens, thin-section CT scans or plain film tomography is indicated.
Next, the lateral aspects of C1 are examined. These aspects should be symmetric, with an equal amount of space on each side of the dens. Any asymmetry is suggestive of a fracture. Finally, the lateral aspects of C1 should line up with the lateral aspects of C2. If they do not line up, there may be a fracture of C1. Figure 6 demonstrates asymmetry in the space between the dens and C1, as well as displacement of the lateral aspects of C1 laterally.
Anteroposterior View
The height of the cervical spines should be approximately equal on the anteroposterior view. The spinous processes should be in midline and in good alignment. If one of the spinous processes is off to one side, a facet dislocation may be present.
Common Cervical Abnormalities
The most common types of cervical abnormalities and their radiographic findings are listed in Table 3. Except for the clay shoveler’s fracture, they should be assumed to be unstable and warrant continued immobilization until definitive therapy can be arranged. Any patient found to have one spinal fracture should have an entire spine series, including views of the cervical spine, the thoracic spine and the lumbosacral spine. The incidence of noncontiguous spine fractures ranges up to 17 percent.27,28 Figures 7 through 9 demonstrate aspects of common cervical spine fractures.
Initial Treatment of Cervical Spine and Cord
If a cervical fracture or dislocation is found, orthopedic or neurosurgical consultation should be obtained immediately. Any patient with a spinal cord injury should begin therapy with methylprednisolone within the first eight hours after the injury, with continued administration for up to 24 hours. Patients should receive methylprednisolone in a dosage of 30 mg per kg given intravenously over one hour. Over the next 23 hours, intravenous methylprednisolone in a dosage of 5.4 mg per kg per hour should be administered. This therapy has been shown to improve outcomes and minimize cord injury,29 although it is not without its problems. The incidence of pneumonia is increased in patients treated with high dosages of methylprednisolone.30
�Sciwora� Syndrome: Unique in Children
A special situation involving children deserves mention. In children, it is not uncommon for a spinal cord injury to show no radiographic abnormalities. This situation has been named �SCIWORA� (spinal cord injury without radiographic abnormality) syndrome. SCIWORA syndrome occurs when the elastic ligaments of a child’s neck stretch during trauma. As a result, the spinal cord also undergoes stretching, leading to neuronal injury or, in some cases, complete severing of the cord.31 This situation may account for up to 70 percent of spinal cord injuries in children and is most common in children younger than eight years. Paralysis may be present on the patient’s arrival in the emergency department. However, up to 30 percent of patients have a delayed onset of neurologic abnormalities, which may not occur until up to four or five days after the injury. In patients with delayed symptoms, many have neurologic symptoms at the time of the injury, such as paresthesias or weakness, that have subsequently resolved.32
It is important to inform the parents of young patients with neck trauma about this possibility so that they will be alert for any developing symptoms or signs. Fortunately, most children with SCIWORA syndrome have a complete recovery, especially if the onset is delayed.33 It is possible to evaluate these injuries with MRI, which will show the abnormality and help determine the prognosis: a patient with complete cord transection is unlikely to recover.3
The treatment of SCIWORA syndrome has not been well studied. However, the general consensus is that steroid therapy should be used.34 In addition, any child who has sustained a significant degree of trauma but has recovered completely should be restricted from physical activities for several weeks.34
Cervical spine radiographs include three standard views, such as the coned odontoid peg view, the anteroposterior view of the entire cervical spine, and the lateral view of the entire cervical spine. Most qualified and experienced healthcare professionals, including chiropractors, offer additional views to visualize the cervicothoracic junction as well as to evaluate the proper alignment of the spine in all patients.�
