  • Colles fx: m/c d/t FOOSH+pronation. m/c inOSP/elder women. Rare in men and if occurs need DEXA to avoid hip Fx etc. Young pts: high-energy trauma. Typically extra-articular.50%-cases show Ulna styloid (US) Fx.
  • Complications: dinner fork deform, CRPS, DJD, nerve entrapment.
  • Imaging: x-rad is sufficient, CT in complex Fx, MRI helps with ligament tears and TFC.
  • Rx: if extra-articular and <5-mm distal radius shortening and <5-degree dorsal angulation closed reduction+casting is sufficient. ORIF in complex cases.
  • �Image Dx: distal rad impaction/shortening,dorsal angulation of distal fragment, carefully examine if intra-articular extension, 50% US Fx

  • Smith Fx: Goyrand in French literature. Considered as reversed Colles, otherwise almost identical, I.e., 85% extra-articular, 50%US Fx, OSP/elderly women, young pts-high-energy trauma. Differences: mechanismFOOSHwith flexed wrist thus m. Less frequent.
  • Imaging steps: (see Colles Fx) C
  • Complications: similar to Colles Fx
  • Rad Dx: 85% extra-articular with volar(anterior) angulation of the distal fragment,radial shortening. Carefully examine cortical breach suspecting intra-articular extension that can be named as Smith type 2 or Reversed Barton Fx (next)
  • Rx: similar approach as in Colles.

  • Barton fx: FOOSH, impaction of distal radius similar to Colles but the Fx line extends from the dorsal radial aspect into radiocarpal joint resulting with dorsal slip/dislocation of the carpus.
  • Imaging: 1st sept x-radiography often with CTto examine intra-articular Fx extension and operative planning
  • Rad Dx: distal radius Fx extending from dorsal into the radiocarpal joint with a variable degree of displacement, the proximal slip of the carpus
  • If Fx line extends from the volar aspect into the wrist joint named Reversed Barton aka Smith type 2 (above bottom image)
  • Complications: similar to all distal radius Fx
  • Rx: operative with ORIF

  • Chauffeur’s/backfire Fx aka Hutchinson Fx: intra-articular Fx of Radial styloid. The name derives from the time when the car had to be started with a hand crank that could backfire inducing wrist dorsiflexion and radial deviation.
  • Imaging: x-radiography is sufficient. CT may be helpful if Fx not readily shown by x-rays.
  • Complications: non-union, malunion, DJD,scapholunate dissociation,lunate/perilunate dislocation
  • Rx: operative with percutaneous lagscrewin all cases d/t intra-articularnature

  • Die-Punch Fx: impaction Fx by the Lunate bone into distal articularLunate fossa of the Radius. IntraarticularFx. Derives its name from a technique to shape (impress) a hole in industrial machining “die-punch.”FOOSH injury.
  • Imaging: 1st step x-rays, may be equivocal d/t subtle depression of the Lunate fossa then CT scanning is most informative.
  • Rad Dx: impacted lunate fossa region with intra-articular Fx extension. This can present as a comminuted Fxarticular Fx of the Distal Radius.
  • Rx: operative d/t intra-articular Fx

  • Scaphoid bone Fx: m/c Fx carpal bone. D/tFOOSH wrist extended radially deviated. Location of Fx is most important to prognosis: Waist-m/c location (70%). May have 70-100%chance of AVN. Proximal pole Fx: 20-30% with a high risk of non-union. Distal pole-10%shows better prognosis. Distal pole Fx is m/c in children. Key clinical sign; pain in the snuffbox.
  • Imaging: 1st step-x-radiography but 15-20%missed d/t occult Fx. Special views required. Thus MRI is the most sensitive and specific for early occult Fx. Bone scintigraphy has98/100% specificity & sensitivity esp. 2-3 days after the onset. Key rad. Dx: Fx line if evident, displacement and obscuration of scaphoid(navicular) fat pad, examine for scapholunate dissociation. If proximal bone appears sclerotic-AVN occurred. MRI: low on T1 & high on T2/STIR/FSPD d/t bone edema, a�low signalFx line can be noted.
  • Rx: Spica cast should be applied if clinically suspected even w/o x-ray findings. For waistFx-cast for 3-mo for prox pole 5-mo immobilization. ORIF or percutaneous pinning with a Herbert screw.

Scapholunate Ligaments Dissociation

  • SNAC wrist: scaphoid non-union advanced collapse. Often d/t non-union and dissociation of scapholunate ligaments (SLL)with progressive radiocarpal and intercarpalDJD. The Proximal scaphoid fragment is attached to Lunate with distal dissociating and rotating�signet ring� sign on x-rays.
  • SNAC wrist may often result in DISI
  • Rx: progressive DJD may lead to four-corner arthrodesis
wrist hand diagnostic imaging el paso tx.
  • Scapholunate advanced collapse (SLAC wrist): SLLdissociation with progressive intercarpal and radiocarpal DJD and volar or dorsal carpal displacement (DISI & VISI). Causes: trauma, CPPD, DJD, Kienboch disease (AVN of Lunate), Preiserdisease (AVN of Scaphoid).
  • SLL dissociation will lead to Dorsal or VolarIntercarlate aka Intercarpal Segmental Instability (DISIor VISI).
  • Rad Dx: Dx underlying cause. X-rays demonstrate dorsal or volar angulation of the Lunate with increased or decreased scapholunate angle on the lateral view. On frontal view: Terry Thomas sign or widening of scapholunate distance 3-4-mm as the upper limit of normal.
  • �MRI may help with ligament evaluation and pre-surgical planning
  • Rx: often operative with late DJD. Four-corner arthrodesis

  • Hook of the Hamate Fx: m/c occurs in batting sports (cricket, baseball, hockey, impact by a golf club, etc.) 2% of carpusFx.
  • Imaging: x-radiography may fail to detect an Fx unless “carpal tunnel view” is used. CT may help if x-rays unrewarding.
  • Clinically: pain, positive pull test, weak, painful grip. Deep ulnar n. Branch may be affected within the�Guyon canal.
  • Rx: usually non-operative, but chronic non-union may require excision.
  • DDx: bipartite hamate
wrist hand diagnostic imaging el paso tx.
  • �Lunate vs. Perilunate dislocation: Lunate is m/c dislocated carpal bone. Overall infrequent carpal injury. However, often missed!
  • Occurs with FOOSH and wrist extended and ulnar deviated. Imaging: 1st step x-rays. Ifunrewarding or require more complex injury evaluation CT scanning.
  • Key Rad DDx: DDx Lunate from perilunate dislocation. Lunate dislocation: lunate lost its contact with distal radius �spilled teacup� on the lateral. Perilunate dislocation: Lunate maintains its contact with distal radius despite the Capitatedorsally dislocated. Lunate dislocation is additionally helped to identify a �pie sign� d/t Lunate overlapping the Capitate
  • Rx: emergency reduction and operative repair of torn ligaments

Metacarpal & Phalangeal Injuries

wrist hand diagnostic imaging el paso tx.
  • Bennett Fx: intra-articular but noncomminuted impact-type Fx of the base of 1st MC bone of the thumb. X-radiography is sufficient.
  • Rad Dx: characteristic triangular fragment of bone on the ulnar aspect of the 1st MCbase, often with radial subluxation of the remaining radial aspect of the 1st MC
  • Complications: DJD, non-union, etc.
  • Rx: prone to instability/non-union requiring an operative care
  • Rolando Fx: aka comminuted Bennett with Y or T-configuration. More complex injury. It is unstable requiring operative care

  • Gamekeeper thumb: traditionally described as a chronic tear of the�ulnar (medial) collateral ligament at 1stMCP in English Gamekeepers’ who performed neck twisting/killing of small game. An acute injury may also be named as Skier’s thumb. This injury can be ligamentous w/o a fracture and an avulsion injury at the 1st proximal phalanx base.
  • Complication: Stener lesion or displacement of torn ligament over Adductor pollicis muscle that cannot heal w/o surgical repair. MRI Dx is required.
  • Avoid thumb stress views that can induce a Stenerlesion
  • Imaging: x-radiography followed by MRI to Dx Stenerlesion. MSK US can be used if MRI is unavailable.
  • �Stener lesion on MRI & MSUS: ulnar collateral stump is more superficial to Adductor pollicis aponeurosis and appears like a low signal mass-like stump forming so-called “yo-yo on the string sign” reported both on MRI and MSK US.
  • Rx: often operative

How Arthritis Can Affect the Knee

How Arthritis Can Affect the Knee

by | Arthritis, Arthropathies, Chiropractic, Chiropractic Examination, Chronic Pain, Conditions Treated, Health, Imaging & Diagnostics, Screening Tests, Sports Injury, Treatments, Wellness

Arthritis is characterized as the inflammation of one or multiple joints. The most common symptoms of arthritis include pain and discomfort, swelling, inflammation, and stiffness, among others. Arthritis may affect�any joint in the human body, however, it commonly develops in the knee. � Knee arthritis can make everyday�physical activities difficult. The most prevalent types of arthritis are osteoarthritis and rheumatoid arthritis, although there are well over 100 distinct forms of arthritis, affecting children and adults alike. While there is no cure for arthritis, many treatment approaches can help treat the symptoms of knee arthritis.

 

Anatomy of the Knee

� The knee is the largest and strongest joint in the human body. It is made up of the lower end of the thigh bone,�or femur, the top end of the shin bone, or tibia, and the kneecap, or patella. The ends of the three bones are covered with articular cartilage, a smooth, slippery structure which protects and cushions the bones when bending and straightening the knee.

� Two wedge-shaped parts of cartilage, known as the meniscus, function as shock absorbers between the bones of the knee to help cushion the joint and provide stability. The knee joint is also surrounded by a thin lining known as the synovial membrane. This membrane releases a fluid which lubricates the cartilage and also helps reduce friction in the knee. The significant kinds of arthritis that affect the knee�include osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.

 

Osteoarthritis

� Osteoarthritis is the most common type of arthritis which affects the knee joint. This form of arthritis is a degenerative, wear-and-tear health issue which occurs most commonly in people 50 years of age and older, however, it may also develop in younger people.

� In osteoarthritis, the cartilage in the knee joint gradually wears away. As the cartilage wears away, the distance between the bones decreases. This can result in bone rubbing and it can�create painful bone spurs. Osteoarthritis generally develops slowly but the pain may worsen over time.

 

Rheumatoid Arthritis

� Rheumatoid arthritis is a chronic health issue which affects multiple joints throughout the body, especially the knee joint. RA is also symmetrical, meaning it often affects the same joint on each side of the human body.

� In rheumatoid arthritis, the synovial membrane that covers the knee joint becomes inflamed and swollen, causing knee pain, discomfort, and stiffness. RA is an autoimmune disease, which means that the immune system attacks its own soft tissues. The immune system attacks healthy tissue,�including tendons, ligaments and cartilage, as well as softens the bone.

 

Post-traumatic Arthritis

� Posttraumatic arthritis is a form of arthritis that develops after damage or injury to the knee. By way of instance, the knee joint may be harmed by a broken bone, or fracture, and result in post-traumatic arthritis years after the initial injury. Meniscal tears and ligament injuries can cause additional wear-and-tear on the knee joint, which over time can lead to arthritis and other problems.

 

Symptoms of Knee Arthritis

� The most common symptoms of knee arthritis include pain and discomfort, inflammation, swelling, and stiffness. Although sudden onset is probable, the painful symptoms generally�develop gradually over time. Additional symptoms of knee arthritis can be recognized as follows:

 

  • The joint may become stiff and swollen, making it difficult to bend and straighten the knee.
  • Swelling and inflammation may be worse in the morning, or when sitting or resting.
  • Vigorous activity might cause the pain to flare up.
  • Loose fragments of cartilage and other soft tissue may interfere with the smooth motion of the joints, causing the knee to lock or stick through motion. It could also creak, click, snap or make a grinding sound, known as crepitus.
  • Pain can cause a sense of fatigue or buckling from the knee.
  • Many individuals with arthritis may also describe increased joint pain with rainy weather and climate changes.

 

 

Diagnosis for Knee Arthritis

� During the patient’s appointment for diagnosis of knee arthritis, the healthcare professional will talk about the symptoms and medical history, as well as conduct a physical examination. The doctor may also order imaging diagnostic tests, such as X-rays, MRI or blood tests for further diagnosis. During the physical examination, the doctor will search for:

 

  • Joint inflammation, swelling, warmth, or redness
  • Tenderness around the knee joint
  • Assortment of passive and active movement
  • Instability of the knee joint
  • Crepitus, the grating sensation inside the joint, with motion
  • Pain when weight is placed on the knee
  • Issues with gait, or manner of walking
  • Any signs of damage or injury to the muscles, tendons, and ligaments surrounding the knee joint
  • Involvement of additional joints (an indicator of rheumatoid arthritis)

 

Imaging Diagnostic Tests

 

  • X-rays. These imaging diagnostic tests produce images of compact structures, such as bones. They can help distinguish among various forms of arthritis. X-rays for knee arthritis may demonstrate a portion of the joint distance, changes in the bone as well as the formation of bone spurs, known as osteophytes.
  • Additional tests. Sometimes, magnetic resonance imaging, or MRI, scans, computed tomography, or CT,�scans, or bone scans are required to ascertain the condition of the bone and soft tissues of the knee.

 

Blood Tests

� Your doctor may also recommend blood tests to determine which type of arthritis you have. With some kinds of arthritis, such as rheumatoid arthritis, blood tests can help with the proper identification of the disease.

 

Dr Jimenez White Coat
Although the knee joint is one of the strongest and largest joints in the human body, it is often prone to suffering damage or injury, resulting in a variety of conditions. In addition, however, other health issues, such as arthritis, can affect the knee joint. In network for most insurances of El Paso, TX, chiropractic care can help ease painful symptoms associated with knee arthritis, among other health issues. Dr. Alex Jimenez D.C., C.C.S.T. Insight

Treatment for Knee Arthritis

 

Non-surgical Treatment

� Non-surgical treatment approaches are often recommended before considering surgical treatment for knee arthritis. Healthcare professionals may recommend a variety of treatment options, including chiropractic care, physical therapy, and lifestyle modifications, among others.

� Lifestyle modifications. Some lifestyle modifications can help protect the knee joint and impede the progress of arthritis. Minimizing physical activities which aggravate the condition, will put less strain on the knee. Losing weight may also help lessen stress and pressure on the knee joint, resulting in less painful symptoms and increased function.

� Chiropractic care and physical therapy.�Chiropractic care utilizes full body chiropractic adjustments to carefully restore any spinal misalignments, or subluxations, which may�be causing symptoms, including arthritis. The doctor may also recommend physical therapy to create an individualized exercise and physical activity program for each patient’s needs.�Specific exercises will help increase range of motion and endurance, as well as help strengthen the muscles in the lower extremities.

� Assistive devices. Using assistive devices, such as a cane, shock-absorbing shoes or inserts, or a brace or knee sleeve, can decrease painful symptoms. A brace helps with function and stability, and may be particularly useful if the arthritis is based on one side of the knee. There are two types of braces that are often used for knee arthritis: A “unloader” brace shifts weight from the affected section of the knee, while a “support” brace helps support the entire knee load.

� Drugs and/or medications. Several types of medications are useful in treating arthritis of the knee. Since individuals respond differently to medications, your doctor will work closely with you to determine the medications and dosages which are safe and effective for you.

 

Surgical Treatment

� The healthcare professional may recommend surgical treatment if the patient’s knee arthritis causes severe disability and only if the problem isn’t relieved with non-surgical treatment. Like all surgeries, there are a few risks and complications with surgical treatment for knee arthritis. The�doctor will discuss the possible problems with the patient.

� Arthroscopy. During arthroscopy, physicians use instruments and small incisions to diagnose and treat knee joint problems. Arthroscopic surgery isn’t frequently used in the treatment of arthritis of the knee. In cases where osteoarthritis is accompanied with a degenerative meniscal tear, arthroscopic surgery may be wise to treat the torn meniscus.

� Cartilage grafting. Normal cartilage tissue may be taken from a tissue bank or through a different part of the knee to fill out a hole in the articular cartilage. This process is typically considered only for younger patients.

� Synovectomy. The lining damaged by rheumatoid arthritis is eliminated to reduce swelling and pain.

� Osteotomy. In a knee osteotomy, either the tibia (shinbone) or femur (thighbone) is cut then reshaped to relieve stress and pressure on the knee joint. Knee�osteotomy is utilized when early-stage osteoarthritis has damaged one facet of the knee joint. By changing the weight distribution, this can relieve and enhance the function of the knee.

� Total or partial knee replacement (arthroplasty).�The�doctor will remove the damaged bone and cartilage, then place new plastic or metal surfaces to restore the function of the knee�and its surrounding structures.

� Following any type of surgery for knee�arthritis will involve a period of recovery. Recovery time and rehabilitation will depend on the type of surgery performed. It’s essential to talk with your healthcare professional to determine the best treatment option for your�knee arthritis. The scope of our information is limited to chiropractic and spinal health issues. To discuss the subject matter, please feel free to ask Dr. Jimenez or contact us at�915-850-0900�.

Additional Topic Discussion: Relieving Knee Pain without Surgery

� Knee pain is a well-known symptom which can occur due to a variety of knee injuries and/or conditions, including�sports injuries. The knee is one of the most complex joints in the human body as it is made-up of the intersection of four bones, four ligaments, various tendons, two menisci, and cartilage. According to the American Academy of Family Physicians, the most common causes of knee pain include patellar subluxation, patellar tendinitis or jumper’s knee, and Osgood-Schlatter disease. Although knee pain is most likely to occur in people over 60 years old, knee pain can also occur in children and adolescents. Knee pain can be treated at home following the RICE methods, however, severe knee injuries may require immediate medical attention, including chiropractic care.

Sagittal Fluid Sensitivity

knee arthritis chiropractic care el paso tx.
  • Sagittal Fluid Sensitive MR slice showing large synovial popliteal (Baker’s) cyst (above top image) and sizeable synovial effusion (above bottom image)
  • Note multiple patchy dark signal areas on both images, representing fibrinoid inflammatory deposits aka “rice bodies” a characteristic MRI feature of RA

Management Rheumatological Referral & DRM

  • Conservative management followed by operative care in complicated cases of tendon ruptures and joints dislocations
  • Supplemental reading:
  • Diagnosis and Management of Rheumatoid Arthritis – AAFP
  • www.aafp.org/afp/2011/1201/p1245.html

Septic Arthritis (SA)

  • Septic arthritis – d/t bacterial or fungal contamination of the joint. SA may cause rapid joint destruction and requires prompt Dx and antibiotic administration
  • Joints affected: large joints with rich blood supply (knee 50%>hips>shoulders).
  • Routs of Infection:
  • 1) Hematogenous is m/c
  • 2) Spread from an adjacent site
  • 3) Direct implantation (e.g., trauma, iatrogenically)
  • Patients at risk: children, diabetics, immunocompromised, pre-existing joint damage/inflammation, e.g., RA, etc.
  • I.V. drug users are particularly at risk and also may contaminate atypical joints “the S joints” SIJ, SCJ, Symphysis pubis, ACJ, etc.

 

  • Clinically: may vary and depends on host immune response and bacterial virulence. May present with rapid onset or exacerbation of pre-existing joint pain, swelling, limitation of ROM. General signs of malaise, fever, fatigue and elevated ESR, CRP, Leucocytosis may be present.
  • N.B. Diabetics and immunocompromised may present with fewer manifestations and lack of fever d/t declining immune response
  • Dx: clinical, radiological and laboratory. Arthrocentesis may be necessary for culture, cell count and purulent synovial examination
  • Management: I.V. antibiotics
  • Imaging Dx: begins with radiography but in the early stage most likely will be unremarkable. MRI can be sensitive and help with early identification of joint effusion, bone edema, etc. US may be helpful in the superficial joints and children. US helps with needle guidance. Bone scintigraphy may be used occaisonally if MRI is contraindicated

Routes of Joint Contamination

knee arthritis chiropractic care el paso tx.

 

  • 1. Hematogenous (M/C)
  • 2. Spread from the adjacent site
  • 3. Direct inoculation
  • M/C organism-Staph aureus
  • N.B Gonococcal infection may be a top differential in some cases
  • IV drug users: Pseudomonas, candida
  • Sickle cell: Salmonella
  • Animal (cats/dogs) bites: Pasteurella
  • Occasionally fungal contamination may occur
knee arthritis chiropractic care el paso tx.

Radiography

knee arthritis chiropractic care el paso tx.

 

  • Initially non-specific ST/joint effusion, obscuration/distortion of fat planes. Because it takes 30% of compact and 50-75% trabecular bone to be destroyed before seen on x-rays, radiography is insensitive to some of the early changes. MR imaging is the preferred modality
  • If MRI is not available or contraindicated. Bone scintigraphy with Tc-99 MDT can help
  • In children, US preferred to avoid ionizing radiation. In children, US can be more sensitive than in adults due to lack of bone maturation

Radiographic Dx

knee arthritis chiropractic care el paso tx.

 

  • Early findings are unrewarding. Early features may include joint widening d/t effusion. Soft tissue swelling and obscuration/displacement of fat planes
  • 1-2 weeks: periarticular and adjacent osseous changes are manifesting as patchy demineralization, moth-eaten, permeating bone destruction, loss, and indistinctness of the epiphyseal “white cortical line” with an increase in soft tissue swelling. MRI may be helpful with early Dx.
  • Late features: complete joint destruction and ankyloses
  • N.B. Septic arthritis may progress rapidly within days and requires early I.V. antibiotic to prevent major joint destruction

T1 & T2 Knee MRI

knee arthritis chiropractic care el paso tx.

 

  • T1 (above left) and T2 fat-sat sagittal knee MRI slices reveal loss of normal marrow signal on T1 and increase on T2 due to septic edema. Bone sequestrum d/t osteomyelitis progressing into septic arthritis is noted. Marked joint effusion with adjacent soft tissue edema is seen. Dx: OSM and septic arthritis
  • Imaging may help the Dx of the septic joint. However, the final Dx is based on Hx, physical examination, blood tests and most importantly synovial aspiration (arthrocentesis)
  • Synovial fluid should be sent for Gram staining, culture, glucose testing, leukocyte count, and differential determination
  • ESR/CRP may be elevated
  • Synovial fluid: WBC can be 50,000-60,000/ul, with 80% neutrophils with depleted glucose levels Gram stain: in 75% gram-positive cocci. Gram staining is less sensitive in gonococcal infection with only 25% of cultures +
  • In 9% of cases, blood cultures are the only source of pathogen identification and should be obtained before antibiotic treatment
  • Articles: www.aafp.org/afp/2011/0915/p653.html
  • www.aafp.org/afp/2016/1115/p810.html

Crystal-Induced Knee Arthritis

  • Crystalline arthritis: a group of arthropathies resulting from crystal deposition in and around the joint.
  • 2-m/c: Monosodium urate crystals (MSU)� and Calcium Pyrophosphate Dehydrate crystals (CPPD) arthropathy
  • Gout: MSU deposition in and around joints and soft tissues. Elevated levels of serum uric acid (UA) (>7mg/dL) caused by overproduction or under-excretion of uric acid
  • Once UA reached/exceeded 7mg/dL, it will deposit in the peripheral tissues. Primary gout: disturbed metabolism of nucleic acids and purines break down. Secondary gout: increased cell turnover: Psoriasis, leukemia, multiple myeloma, hemolysis, chemotherapy, etc.
  • Gout presents with 5-characteristic stages:
  • 1)asymptomatic hyperuricemia (years/decades)
  • acute attacks of gouty arthritis (waxes and wanes and lasts for several years)
  • Interval phase between attacks
  • Chronic tophaceous gout
  • Gouty nephropathy

Degenerative Knee Arthritis

  • Knee Arthritis
  • Knee OA (arthrosis) is the m/c symptomatic OA with 240 cases per 100,000, 12.5% of people >45 y.o.
  • Modifiable risk factors: trauma, obesity, lack of fitness, muscle weakness
  • Non-modifiable: women>men, aging, genetics, race/ethnicity
  • Pathology: da disease of the articular cartilage. Continuing mechanical stimulation follows by an initial increase in water and cartilage thickness. Gradual loss of proteoglycans and ground substance. Fissuring/splitting. Chondrocytes are damaged and release enzymes into the joint. Cystic progression and further cartilage loss. Subchondral bone is denuded and exposed to mechanical stresses. It becomes hypervascular forming osteophytes. Subchondral cysts and bone thickening/sclerosis develop.
  • Imaging plays a crucial role in Dx/grading and management
  • Clinically: pain on walking/rest, crepitus, swelling d/t synovitis, locking/catching d/t osseocartilaginous fragments and gradual functional loss. Knee OA typically presents as mono and oligoarthritis. DDx: morning pain/stiffness is >30-min DDx from inflammatory arthritis
  • Treatment: in mild to moderate cases-conservative care. Severe OA-total knee arthroplasty

OA: L.O.S.S. Radiologic Presentation

knee arthritis chiropractic care el paso tx.

 

  • Typical radiologic-pathologic presentation of� OA: L.O.S.S.
  • Loss of joint space (non-uniform/asymmetrical)
  • Osteophytes
  • Subchondral sclerosis
  • Subchondral cysts
  • Bone deformity: Genu Varum- is the m/c deformity d/t medial knee compartment affected more severely
  • In addition: a weakening of periarticular soft tissues, instability and other changes

Imaging

knee arthritis chiropractic care el paso tx.

 

  • Radiography is the modality of choice
  • Views should include b/l weight bearing
  • Evaluation of joint space is crucial. Normal joint space -3-mm
  • Grading is based on the degree of joint space narrowing (JSN), osteophytes, bone deformation, etc.
  • Grade 1: minimal JSN, suspicious osteophytes
  • Grade 2: appreciable osteophytes and JSN on AP weight-bearing view
  • Grade 3: multiple osteophytes, definite JSN, subchondral sclerosis
  • Grade 4: severe JSN, large osteophytes, marked subchondral sclerosis and definite bony deformity
  • Typical report language will state:
  • Minor, mild, moderate or severe aka advanced arthrosis

Technique

knee arthritis chiropractic care el paso tx.

 

  • Radiography: AP weight-bearing knees: note severe JSN of the medial compartment more severely with lateral knee compartment. Osteophytes and marked genu varum deformity and bone deformation
  • Typically medial femorotibial compartment is affected early and more severely
  • The patellofemoral compartment is also affected and best visualized on the lateral and Sunrise views
  • Impressions: severe tri-compartmental knee arthrosis
  • Recommendations: referral to the orthopedic surgeon

Moderate JSN

knee arthritis chiropractic care el paso tx.

 

  • B/L AP weight-bearing view (above top image): Moderate JSN primarily of the medial femorotibial compartment. Osteophytosis, subchondral sclerosis and mild bone deformation (genu varum)
  • Additional features: PF OA, intra-articular osteophytes, secondary osteocartilaginous loose bodies and subchondral cysts (above arrows)

Secondary Osteochondromatosis

knee arthritis chiropractic care el paso tx.

 

  • Intra-articular osteocartilaginous loose bodies known as secondary osteochondromatosis
  • Typical in DJD especially of the large joints
  • It may accelerate further cartilage destruction and progression of OA
  • May worsen signs of synovitis
  • Intra-articular locking, catching etc.

Management of Severe Knee OA

knee arthritis chiropractic care el paso tx.

 

  • Conservative care: NSAID, exercise, weight loss etc.
  • Operative care should be used if conservative care failed or symptoms progress despite conservative efforts in severe OA cases
  • Review article
  • www.aafp.org/afp/2018/0415/p523.html

Calcium Pyrophosphate Dehydrate Deposition Disease

knee arthritis chiropractic care el paso tx.

 

  • CPPD arthropathy common in the knee
  • May present as asymptomatic chondrocalcinosis, CPPD arthropathy resembling DJD with pan predominance of large subchondral cysts. Often found as isolated PFJ DJD
  • Pseudogout with an acute attack of knee pain resembling gouty arthritis
  • Radiography is the 1st step and often reveals the Dx
  • Arthrocentesis with polarized microscopy may be helpful to DDx between CPPD and Gouty arthritis

Rheumatoid Arthritis

  • RA: an autoimmune systemic inflammatory disease that targets soft tissues of joints synovium, tendons/ligaments, bursae and extra-articular sites (e.g., eyes, lungs, cardiovascular system)
  • RA is the m/c inflammatory arthritis, 3% of women and 1% of men. Age: 30-50 F>M 3:1, but may develop at any age. True RA is uncommon in children and should not be confused with Juvenile Idiopathic Arthritis
  • RA most often affects small joints of the hands and feet as symmetrical arthritis (2nd 3rd MCP, 3rd PIPs, wrists & MTPs, sparing DIPs of fingers and toes)
  • Radiographically: RA presents with joint effusion leading to hyperemia and marginal erosions and periarticular osteoporosis. In the knee, the lateral compartment is affected more frequently leading to valgus deformity. Uniform aka concentric/symmetrical JSN affects all compartments and remains a key Dx clue
  • An absence of subchondral sclerosis and osteophytes. Popliteal cyst�(Baker’s cyst) may represent synovial pannus and inflammatory synovitis extending into the popliteal region that may rapture and extend into posterior leg compartment
  • N.B. Following initial RA joint destruction, it is not unusual to note superimposed 2nd OA
  • Radiography is the 1st step but early joint involvement may be undetectable by x-rays and can be helped by US and/or MRI.
  • Lab tests: RF, CRP, anti-cyclic citrulline peptide antibodies (anti-CCP Ab). CBC
  • Final Dx is based on Hx, clinical exam, labs, and radiology
  • Clinical pearls: patients with RA may present with a single knee being affected
  • Most patients are likely to have bilateral symmetrical hands/feet RA.
  • Cervical spine, particularly C1-2 is affected in 75-90% of cases throughout the course of the disease
  • N.B. Sudden exacerbation of joint pain in RA should not underestimate septic arthritis because patients with pre-existing RA are at higher risk of infectious arthritis. Joint aspiration may help with Dx.

Radiographic DDx

knee arthritis chiropractic care el paso tx.

 

  • RA (above left) vs. OA (above right)
  • RA: concentric (uniform) joint space loss, lack of osteophytes and juxta-articular osteopenia.
  • Clinical Pearls: patients with RA may present radiographically with subchondral sclerosis d/t superimposed DJD. The latter feature should not be interpreted as OA but instead considered as secondary OA

AP Knee Radiograph

knee arthritis chiropractic care el paso tx.

 

  • Note marked uniform JSN, juxta-articular osteopenia and subchondral cystic changes
  • Clinical Pearls: subcortical cysts in RA will characteristically lack sclerotic rim noted in OA-associated subcortical cysts.

MRI Sensitivity

knee arthritis chiropractic care el paso tx.

 

  • MRI is very sensitive and may aid during early Dx of RA.
  • T2 fat-sat or STIR and T1 + C gad contrast fat-suppressed sequences may be included
  • MRI Dx of RA: synovial inflammation/effusion, synovial hyperplasia, and pannus formation decreased cartilage thickness, subchondral cysts, and bone erosions
  • MRI is very sensitive to reveal juxt-articular bone marrow edema, a precursor to erosions
  • Intra-articular fibrinoid fragments known as “Rice bodies” are characteristic MR sign of RA
  • Note: T2 fat-sat sagittal MRI revealing large inflammatory joint effusion and pannus synovial proliferation (above arrowheads). No evidence of radiographic or MRI bone erosions present. Dx: RA

STIR MR Slices

knee arthritis chiropractic care el paso tx.

 

  • Note: STIR MR slices in the axial (above bottom image) and coronal planes (above top image) demonstrate extensive synovitis/effusion (above arrowheads) and multiple erosions in the medial and lateral tibial plateau (above arrows)
  • Additionally, scattered patchy areas of bone marrow edema are noted (above asterisks) such marrow edema changes are indicative and predictive of future osseous erosions.
  • Additional features: note thinning and destruction of joint cartilage

Ischemic Osteonecrosis

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Ischemic Osteonecrosis (More accurate term) aka avascular necrosis AVN: this term describes subarticular (subchondral) bone death
  • Intramedullary bone infarct: depicts osteonecrosis within the medullary cavity of the bone (above x-ray image)
  • Causes: m/c: trauma, systemic corticosteroids, diabetes, vasculitis in SLE. The list is long. Other vital causes: Sickle cell disease, Gaucher disease, alcohol, caisson disease, SCFE, LCP, etc.
  • Pathology: ischemia and bone infarct with resultant devitalized center surrounded by ischemia and edema with normal bone on the outer periphery (MRI double line sign)
  • Sub-articular necrotic bone eventually collapses and fragments leading to progressive bone and cartilage destruction and rapidly progressing DJD
  • Early Dx often missed but crucial to prevent severe DJD

M/C Sites

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Hips, shoulders, talus, scaphoid bone. Many peripheral idiopathic AVN sites are known by their eponyms (e.g., Kienbock aka AVN of the lunate bone, Preisier aka scaphoid AVN)
  • Radiography is insensitive to early AVN and may only present as subtle osteopenia
  • Some of the early appreciable rad features are increased patchy bone sclerosis followed by sub-articular bone collapse or “crescent sign” signifying stage-3 on Ficat classification (above)
  • Earliest detection and early intervention can be achieved by MRI (most sensitive modality)
  • If MRI contraindicated or unavailable, 2nd most sensitive modality is radionuclide bone scan (scintigraphy)
  • X-ray and CT scanning are of equal value

Coronal MRI Slice

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Fluid sensitive, sensitive coronal MRI slice revealing bill ischemic osteonecrosis of the femoral head
  • MRI findings: l

Tc99-MMDP Radionuclide Bone

  • Bone scan reveals a central area of photopenia (cold spot) d/t necrotic fragment surrounded by increased osteoblastic activity as increased uptake of Tc-99 MDP in the right hip
  • The patient is a 30-year-old female with breast cancer and chemotherapy treatment who suddenly presented with right hip pain

Radiographic Progression of AVN

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Later stages present with articular collapse, subarticular cysts, increased patchy sclerosis and complete flattening of the femoral head with resultant severe DJD. Rx: THA

Management

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Early imaging Dx with MRI or bone scintigraphy is essential
  • Referral to the Orthopedic surgeon
  • Core decompression (above) can be used to revascularize the affected bone during earlier stages but produces mixed results
  • Delayed changes of AVN: THA as IN severe DJD cases

B/L THA

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • B/L THA in the patient with ischemic osteonecrosis of the right and later left hip
  • When B/L hip AVN is present, typically consider systemic causes (corticosteroids, diabetes)

Inflammatory Arthritis Affecting the Hip

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Consider common systemic inflammatory condition such as RA and AS/EnA
  • Hip RA may develop in 30% of patients with RA
  • Key features to DDx inflammatory arthritis vs. DJD is symmetrical/uniform aka concentric joint loss often leading to axial migration and Protrusion Acetabule in advanced cases
  • Key element between RA vs. AS: the presence of RA bone erosion w/o productive bone changes or enthesitis in AS d/t inflammatory subperiosteal bone proliferation, whiskering/fluffy periostitis (collar-type enthesitis circumferentially affecting head-neck junction)
  • Dx: Hx, PE, labs: CRP, RH, anti-CCP Ab (RA)
  • CRP, HLA-B27, RF- (AS)

Septic Arthritis

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Gonococcal infections, iatrogenic causes, I.V. drug use, and some others
  • Routes:�hematogenous, adjacent spread, direct inoculation (e.g., iatrogenic)
  • Clinically: pain and reduced ROM presented as monoarthritis, generalized signs/symptoms. CBC, ESR, CRP changes. ARthrocentesis and culture are crucial
  • M/C pathogen Staph. Aureus & Neisseria Gonorrhea
  • 1st step: radiography, often unrewarding in the early stage. Later (4-10 days) indistinctness of the white cortical line at the femoral articular epiphysis, loss of joint space, effusion as a widening of the medial joint area (Waldenstrom sign)
  • MRI – best at early DX: T1, T2, STIR, T1+C may help with early. Early I.V. antibiotics crucial to prevent rapid joint destruction

Slipped Capital Femoral Epiphysis (SCFE)

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Important to diagnose but easily missed potentially leading to Ischemic Osteonecrosis of the femoral head aka AVN
  • Presents typically in overweight children (more often boys), age over eight years. Greater incidence in African-American boys
  • 1st step: radiography, especially look for a widened physeal growth plate (so-called pre-slip). Later, slip and disturbed Klein’s line (above image). MRI – best modality for early Dx and early intervention
  • The frog lateral view often demonstrates the medial slip better than the AP view

Clinically Limping Child or Adolescent

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • M>F (10-18 years). African-Americans are at greater risk. 20% of cases of SCFE are B/L. Complications: AVN >>DJD
  • Radiography:�AP pelvis, spot, and frog leg may reveal slippage as Klein line failed to cross through the lateral aspect of the femoral head
  • Additional features: physis may appear widened
  • MRI w/o gad, is required for the earliest Dx and prevention of complications (AVN)

Normal and Abnormal Klein Line

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Consistent with SCFE. The physis is also widened. Dx: SCFE
  • Urgent referral to the Pediatric Orthopedic surgeon

Subtle Changes in Left Hip

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • Note suspected subtle changes in the left hip that may require MR examination to confirm the Dx
  • Delay in care may result in major complications

Perthes’ Disease

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • aka Legg-Calves-Perthes Disease (LCP)
  • Refers to Osteochondritis of the femoral head with osteonecrosis likely d/t disturbed vascularization of the femoral head
  • Presents typically in children (more often boys) aged under eight years as atraumatic “limping child.” 15% may have B/L Perthe’s
  • Imaging steps: 1st step x-radiography, followed by MRI especially in stage 1 (early) w/o x-ray abnormalities
  • Unspecific signs: joint effusion with Waldenstrome sign+ (>2-mm increase in medial joint space compared to the opposite side). Past approach: Fluoroscopic Arthrography (replaced by MRI)
  • Pathologic-Radiologic Correlation: in well-established cases, the femoral head characteristically becomes sclerotic, flattened and fragmented due to avascular necrosis (AVN). Later on, an occasional Coxa Magna changes may develop (>10% femoral head enlargement)
  • Management: symptoms control, bracing. Boys at younger ate show better prognosis d/t more immaturity and better chances of bone/cartilage repair mechanisms. In advanced cases, operative care: osteotomy, hip arthroplasty in adulthood if advanced DJD develops

Common Neoplasms & Other Conditions Affecting Hip/Pelvis

diagnosis hip arthritis and neoplasms el paso, tx.

 

  • M/C hip & pelvis neoplasms in adults: bone metastasis ( above far left), 2nd m/c Multiple Myeloma (M/C primary bone malignancy in adults). Tips: remember Red Marrow distribution. Less frequent: Chondrosarcoma

AP Hip Radiograph Demonstrates DJD

diagnosis hip arthritis and neoplasms el paso tx.
  • With a non-uniform loss of joint space (superior migration), large subcortical cysts and subchondral sclerosis
  • Radiographic features:
  • Like with any DJD changes: radiography will reveal L.O.S.S.
  • L: loss of joint space (non-uniform or asymmetrical)
  • O: osteophytes aka bony proliferation/spurs
  • S: Subchondral sclerosis/thickening
  • S: Subcortical aka subchondral cysts “geodes.”
  • Hip migration is m/c superior resulting in a “tilt deformity.”

Radiographic Presentation of Hip OA May Vary Depending On Severity

diagnosis hip arthritis and neoplasms el paso tx.
  • Mild OA: mild reduction of joint space often w/o marked osteophytes and cystic changes
  • During further changes, collar osteophytes may affect femoral head-neck junction with more significant joint space loss and subchondral bone sclerosis (eburnation)
  • Cyst formation will often occur along the acetabular and femoral head subarticular/subchondral bone “geodes” and usually filled with joint fluid and some intra-articular gas

Ankylosing Spondylitis Sufferers Find Relief With Chiropractic. El Paso, TX.

Ankylosing Spondylitis Sufferers Find Relief With Chiropractic. El Paso, TX.

by | Arthritis, Arthropathies, Chronic Pain

Ankylosing Spondylitis is a type of arthritis that typically begins during adolescence or in a person�s early twenties and occurs more often in men than in women. However, once experiences onset, they are affected for the rest of their lives. It is estimated that between 0.2% and 0.5% of individuals in the United States suffers from ankylosing spondylitis. �It can cause significant pain, discomfort, and immobility. While there is no cure for the condition, the symptoms can be treated, bringing some degree of comfort and mobility.

What is Ankylosing Spondylitis?

Ankylosing Spondylitis, or AS, is a type of arthritis that causes inflammation in the spine. While the vertebrae are primarily involved, it can also affect other joints as well, including the hips, shoulders, heels, ribs, and the small joints of the feet and hands.

In some cases, the heart, lungs, and even eyes can be involved. If left untreated, the condition can progress, causing chronic pain that can be severe as the spinal inflammation increases. More advanced cases can cause the spine to grow new bone formations so that it is immobile, or fixed, sometimes resulting in kyphosis, which is a bowed or forward-stooped posture.

What Causes Ankylosing Spondylitis?

While genetics is believed to be a key player in the development of Ankylosing Spondylitis, the exact cause has not yet been determined. The majority of people who have AS also carry a specific gene that has been linked to the condition.

This gene produces HLA-B27, a protein or genetic marker, that more than 95% of Caucasians with ankylosing spondylitis have. However, some people don�t have this protein who develop AS and many people do carry this marker yet never develop the condition.

Researchers theorize that there may be other genes that may be involved, as well as environmental factors that trigger the gene activation, such as a bacterial infection, causing people who are susceptible to AS to activate it. Scientists have identified more than 60 genes that are believed to be associated with AS with only about 30% that are linked to HLA-B27 regarding overall risk. Other genes that have been identified as key to AS include IL-23, IL-17, IL-12, and ERAP.

It is also believed that AS can be triggered when the intestinal defenses break down, allowing certain bacteria into the bloodstream. This can, in turn, cause an immune response.

Ankylosing Spondylitis chiropractic treatment el paso tx.

How is Ankylosing Spondylitis Treated?

AS cannot be cured, but the symptoms can be treated to relieve stiffness and pain as well as delay or prevent spinal deformity and other complications. The damage that it does to the joints is irreversible, so it is best if treatment is started before that occurs. There are several ways that AS is treated:

  • Medication � Nonsteroidal anti-inflammatory drugs (NSAIDs) like indomethacin (Indocin) and naproxen (Naprosyn) are commonly used to treat the symptoms of AS. They can be useful in relieving pain, inflammation, and stiffness but may cause some side effects, including gastrointestinal bleeding. This makes long-term use impractical and even unsafe. If NSAIDs do not help, other medications may be prescribed, including:
    • Golimumab (Simponi; Simponi Aria)
    • Certolizumab pegol (Cimzia)
    • Adalimumab (Humira)
    • Etanercept (Enbrel)
    • Infliximab (Remicade)
  • Physical therapy – PT is often recommended to help with flexibility, strength, and pain relief. It can help with posture and prevent some of the more debilitating symptoms.
  • Surgery � Most people with AS do not require surgery, but it may be recommended if there is severe joint damage or pain. In some cases, it can cause significant damage to hip joints, and they will need to be replaced.
  • Chiropractic � Many patients with AS have with outstanding results with chiropractic treatment. It is non-invasive and does not have the unpleasant side effects that many medications have.

Chiropractic Treatment for Ankylosing Spondylitis

Chiropractors strongly recommend chiropractic treatment for the non-acute inflammatory stage of AS. Once the condition has progressed to acute joint disease, there is a very high risk of injury or damage to the connective tissue. Adjustments and exercise are used to relieve symptoms, but some of the traditional spinal manipulation treatments are not performed.

A chiropractor will also make recommendations to the patient regarding lifestyle changes that can help with symptoms, such as stopping smoking. Tobacco use can increase inflammation and damage connective tissue. They may also advise increasing their intake of omega three fatty acids in their diet. Regular chiropractic care can help patients manage symptoms and prevent disease progression, improving their quality of life.
