Nerve Injury

Back Clinic Nerve Injury Team. Nerves are fragile and can be damaged by pressure, stretching, or cutting. Injury to a nerve can stop signals to and from the brain, causing muscles not to work properly and losing feeling in the injured area. The nervous system manages a great majority of the body’s functions, from regulating an individual’s breathing to controlling their muscles as well as sensing heat and cold. But, when trauma from an injury or an underlying condition causes nerve injury, an individual’s quality of life may be greatly affected. Dr. Alex Jimenez explains various concepts through his collection of archives revolving around the types of injuries and condition which can cause nerve complications as well as discuss the different form of treatments and solutions to ease nerve pain and restore the individual’s quality of life.

Exploring the Axillary Nerve: Structure and Innervation

Exploring the Axillary Nerve: Structure and Innervation

An axillary nerve injury can cause pain, weakness, and shoulder mobility loss. Can physical therapy help restore and maintain shoulder joint flexibility?

Exploring the Axillary Nerve: Structure and Innervation

Axillary Nerve

The axillary nerve, or the circumflex nerve, is a peripheral nerve that runs through the shoulder and supports movement and sensation in the upper limbs. It originates in the neck at the brachial plexus, a network of nerves that extends from the neck and upper torso to the shoulders and arms. Its primary purpose is to supply nerve function to the shoulder joint and three muscles in the arm and also innervates some skin in the region.

Anatomy

Except for the cranial nerves, all the body’s nerves branch off from the spinal cord, emerge from between vertebrae and continue to branch off as they travel to various muscles and other structures. The axillary nerve is named after the axilla, the medical name for the armpit. Individuals have two, one on each side. After leaving the spinal column, the axillary nerve runs behind the axillary artery and continues to the shoulder blade’s lower edge of the subscapularis muscle. It winds back and travels down the arm along the posterior humeral circumflex artery, which then passes through the quadrangular space (a small area of the shoulder blade just above the armpit where there is a gap in the muscles that allows nerves and blood vessels to pass through to the arm before it divides into terminal branches, which are:

Anterior Division

  • Supplies motor innervation to the deltoid’s anterior and middle heads, allowing the arm to abduct or move away from the body.
  • It winds around the neck of the humerus/funny bone, goes beneath the deltoid muscle, and then connects to the forward edge of the deltoid.
  • A few small cutaneous branches serve the skin in that area.

Posterior Division

  • Innervates the teres minor muscles and the lower part of the deltoid.
  • It enters the deep fascia and becomes the superior lateral cutaneous nerve.
  • It then wraps around the lower edge of the deltoid, connects to the skin over the lower two-thirds of the muscle, and covers the long head of the triceps brachii.

Articular Branch

  •  Comes from the trunk of the axillary nerve and enters the glenohumeral joint, which is in the shoulder, below the subscapularis muscle.

Anatomical Variations

In a case report, healthcare providers noted an incidence of the nerve branching directly off the upper trunk of the brachial plexus rather than the posterior cord. (Subasinghe S. K. and Goonewardene S. 2016) In this case, it innervated the subscapularis muscle, latissimus dorsi, and the deltoid and teres minor muscles and also had a communicating branch to the posterior cord. Another case documented multiple abnormalities in the course of the axillary nerve in an individual with pain and severely limited shoulder mobility. (Pizzo R. A. et al., 2019) During reverse shoulder arthroplasty, the surgeon discovered that the axillary nerve ran beside the coracoid process instead of underneath and stayed close to the subscapularis muscle instead of traveling through the quadrangular space. The case noted earlier reports of axillary nerves not running through the quadrangular space. In those cases, the nerve pierced the subscapularis muscle or split into branches before reaching the quadrangular space.

Function

The axillary nerve functions as a motor nerve that controls movement and a sensory nerve that controls sensations like touch or temperature.

Motor

As a motor nerve, the axillary nerve innervates three muscles in the arm and includes:

Deltoid

  • Allows flexing of the shoulder joint and rotating the shoulder inward.

Long Head of the Triceps

  • It runs down the back of the outer arm, allowing straightening, pulling the upper arm toward the body, or extending it backward.
  • The radial nerve can also innervate this muscle.

Teres Minor

  • One of the rotator cuff muscles starts outside the shoulder and runs diagonally along the bottom edge of the shoulder blade.
  • It works with other muscles to allow for the external rotation of the shoulder joint.

Sensory

In its sensory role, the nerve carries information to the brain from the following:

  • Glenohumeral joint or the ball-and-socket joint in the shoulder.
  • The skin on the lower two-thirds of the deltoid muscle through the superior lateral cutaneous branch.

Injuries and Conditions

Problems with the axillary nerve can be caused by injuries anywhere along the arm and shoulder and by disease. Common injuries include:

Dislocations

  • Of the shoulder joint, which can cause axillary nerve palsy.

Fracture

  • Of the surgical neck of the humerus.

Compression

  • This stems from walking with crutches, also known as crutch palsy.

Direct Trauma

  • This can be from an impact sports, work, automobile accident, collision, or laceration.

Added Pressure

  • This can be from wearing a cast or splint.

Surgical Accidental Injury

  • An injury or damage can come from shoulder surgery, especially arthroscopic surgery on the inferior glenoid and capsule.

Quadrangular Space Syndrome

  • This is where the axillary nerve is compressed where it passes through that space, which is most common in athletes who perform frequent overhead motions)

Nerve Root Damage

  • Between the fifth and sixth cervical vertebrae, where the nerve emerges from the spinal cord, which can be caused by traction, compression, spinal disc prolapse, or a bulging disc.

Systemic Neurological Disorders

  • Example – multiple sclerosis

Erb’s Palsy

  • A condition often is the result of a birth injury called shoulder dystocia, in which a baby’s shoulder/s becomes stuck during childbirth.

Axillary Nerve Palsy

  • Damage can result in a type of peripheral neuropathy that can cause weakness in the deltoid and teres minor muscles.
  • This can result in losing the ability to lift the arm away from the body and weakness in various shoulder movements.
  • If the damage is severe enough, it can cause paralysis of the deltoid and other minor muscles, resulting in flat shoulder deformity, in which individuals cannot lay their shoulders flat when lying down.
  • Axillary nerve damage also can lead to a change, reduction, or loss of sensation in a small part of the arm just below the shoulder.

Nerve Injury Statistics

  • Three times more common in men than women.
  • It may be present in as many as 65% of shoulder injuries.
  • The risk of injury due to dislocation is significantly increased after age 50.

Tests

If a healthcare provider suspects a problem with axillary nerve function, they’ll test the shoulder’s range of motion and skin sensitivity. A difference in the range of motion between the shoulders can indicate a nerve injury. Individuals may be sent for electromyography and a nerve conduction study to verify nerve palsy. In some cases, an MRI and/or X-rays may be ordered, especially if the cause of possible nerve damage is unknown.

Rehabilitation

Depending on the severity and cause of the injury, non-surgical treatments may be recommended, with surgery as a last resort. Non-surgical treatment can include some combination of immobilization, rest, ice, physical therapy, and anti-inflammatory meds. Physical treatment typically lasts about six weeks and focuses on strengthening and stimulating the muscles to prevent joint stiffness, which can impair long-term function.

Surgery

If conservative treatments don’t work, surgery may be recommended, especially if several months have passed without improvement. Surgical outcomes are generally better if surgery is performed within six months of the injury, and regardless of the time frame, the prognosis is considered positive in about 90% of cases. Surgical procedures performed for axillary nerve dysfunction or injury include:

Neurolysis

  • This procedure involves targeted damage/degeneration of nerve fibers, interrupts the nerve signals, and eliminates pain while the damaged area heals.

Neurorrhaphy

  • This procedure stitches a severed nerve back together.

Nerve Grafting

  • Grafting involves transplanting a portion of another nerve, usually the sural nerve, to reconnect severed nerves.
  • This helps, especially when the damaged portion is too large to be repaired by neurorrhaphy.
  • It allows a pathway for signals and encourages the regrowth of nerve axons.

Neurotization or Nerve Transfer

  • Similar to grafting but used when the nerve is too damaged to heal.
  • This procedure involves transplanting a healthy but less important nerve, or a portion of a nerve, to replace the damaged one and restore function.

Dealing with Arm Numbness: Causes and Remedies

Dealing with Arm Numbness: Causes and Remedies

Can determining whether arm numbness occurs suddenly or gradually and whether there are other symptoms help healthcare providers diagnose and treat the condition?

Dealing with Arm Numbness: Causes and Remedies

Arm Numbness

Arm numbness or tingling are common symptoms that various medical conditions can cause. Numbness can be caused by a sudden health emergency, nerve disorder, or nutritional deficiency. (National Institute of Neurological Disorders and Stroke, 2024) Sometimes, this symptom results from an arm falling asleep and could resolve after just a few minutes. The sensation may be temporary, caused by something like sleeping in the wrong position. However, arm numbness and tingling may also be caused by neuropathy and chronic and progressive nerve damage and can also suddenly occur due to serious conditions, such as a heart attack or a stroke.

Circulation Issues

Deficient blood circulation in the arm could cause numbness and tingling as the nerves cannot receive enough oxygen. Conditions can interfere with normal blood flow and include: (Bryan L. and Singh A. 2024)

  • Atherosclerosis – plaque buildup in the arteries that may require medication or surgery.
  • Severe frostbite can damage the blood vessels but can be resolved with proper warming and wound care.
  • Vasculitis – is inflammation of the blood vessels that can be treated with medication.

Sleeping Position

A common example of sudden numbness and tingling is the feeling that the arm has fallen asleep. This usually occurs after sleeping awkwardly or leaning on the arm for a long time. Known as paresthesia, this sensation is related to the compression or irritation of nerves. (Bryan L. and Singh A. 2024) Sleeping in certain positions has been associated with nerve compression, especially when the hands or wrists are tucked or curled under the body, as well as maintaining proper spine alignment when sleeping, is the best way to prevent arm numbness.

Nerve Injuries and Conditions

Numbness that persists may be related to an injury or underlying health problem that affects the brachial plexus, a group of nerves that runs from the lower neck to the upper shoulders and controls movement and sensation in the arms. (Mount Sinai, 2022) Possible injuries that affect these nerves include: (Smith, S. M. et al., 2021)

  • A herniated disc caused by aging or trauma causes the disc to leak out and press on the nerve root.
  • Burner or stinger injuries that affect the neck and shoulders.
  • Backpacker’s palsy is caused by pressure on the shoulders.
  • Birth injuries such as Erb-Duchenne’s palsy and Klumpke’s palsy.
  • Traumatic nerve root avulsion injury in which spinal nerves are damaged.

Diseases and disorders that can cause numbness in the arms include conditions that affect the nervous system, like multiple sclerosis, fibromyalgia, Raynaud phenomenon, and shingles. (National Heart, Lung, and Blood Institute, 2023) (Smith, S. M. et al., 2021)

Numbness and Serious Health Conditions

Stroke

  • This is a medical emergency in which a blockage prevents blood from getting to the brain.
  • One sign of a stroke is a tingling sensation on one side of the body.
  • Individuals may also be unable to move one or more limbs. (Centers for Disease Control and Prevention, 2024)
  • Seek emergency medical care.

Heart Disease

  • When the heart is damaged, blood cannot circulate and can lead to a minor or major heart attack.
  • Signs of a heart attack include numbness in one or both arms, and it is not always the left arm. (National Heart, Lung, and Blood Institute, 2022)
  • Pressure pain in the chest and shortness of breath are other signs that require immediate medical attention.

Spinal Osteoarthritis

Cancer

  • Neoplasm tumors can affect the brachial plexus nerves, causing loss of feeling in the arms.
  • Breast and lung cancers are the most likely. (Smith, S. M. et al., 2021)

Diabetes

  • Loss of feeling in the arms can be a sign of peripheral neuropathy, which can be caused by uncontrolled diabetes. (Johns Hopkins Medicine, 2024)
  • Treatment requires managing blood sugar and oral and topical medications.

Medication Numbness

The relationship between arm numbness and medication usage can be complex. (Senderovich H. and Jeyapragasan G. 2018)

  • Many medications, like gabapentin, can be used to alleviate the sensations of arm numbness.
  • Some medications can cause numbness as a side effect.
  • Some medications can cause complications, and arm numbness could be a symptom of those complications.

Inform healthcare providers about medications being taken to determine the relationship between them and any sensory changes.

Vitamin Deficiency

Peripheral neuropathy can also be caused by nutritional deficiencies and vitamin imbalances, which can damage nerves and cause sensation loss in the left or right arm. The most common sources are vitamin B12 deficiency and excess vitamin B6. (National Institute of Neurological Disorders and Stroke, 2024) Excessive alcohol consumption and other disorders that affect nutritional intake can also lead to nerve damage.

Meralgia Paresthetica: Causes, Symptoms, and Treatment Options

Meralgia Paresthetica: Causes, Symptoms, and Treatment Options

Individuals experiencing pain, numbness, tingling, or a burning sensation in the front and outer thigh could have meralgia paresthetica, a nerve entrapment. Can understanding the condition help healthcare providers develop an effective treatment plan?

Meralgia Paresthetica: Causes, Symptoms, and Treatment Options

Meralgia Paresthetica

Meralgia paresthetica, or MP, is also known as Bernhardt-Roth syndrome, lateral femoral cutaneous nerve syndrome, or lateral femoral cutaneous neuralgia. It occurs when the lateral femoral cutaneous nerve, a sensory nerve that passes over the brim of the pelvis and down the front of the thigh, becomes compressed. The nerve supplies information about sensations over the front and outside of the thigh. This can happen for several reasons, including:

  • Recent hip injuries, such as from a motor vehicle collision/accident.
  • Repetitive hip activities, like cycling.
  • Pregnancy
  • Weight gain
  • Wearing tight clothing.

The nerve entrapment condition causes tingling, numbness, and burning pain in the front and/or outer thigh.

Causes

There can be several different causes of this condition, but it is frequently seen in pregnancy, sudden weight gain, wearing tight clothing or belts, and other conditions. (Ivins G. K. 2000) Sometimes, meralgia paresthetica can be caused by medical procedures. For example, the condition can present after an individual has surgery and is in an unusual position for a long period of time, where there is direct external pressure on the nerve. Also, the nerve can become damaged during a surgical procedure. (Cheatham S. W. et al., 2013) This can occur when a bone graft is obtained from the pelvis or anterior hip replacement surgery.

Symptoms

Individuals may experience some or all of the following symptoms (Chung K. H. et al., 2010)

  • Numbness over the outside of the thigh.
  • Pain or burning on the outside of the thigh.
  • Sensitivity to lightly touching the outside of the thigh.
  • Worsening of symptoms with certain positions.
  • Increased symptoms when wearing belts, work belts, or tight-waist clothes.

The symptoms may come and go or be persistent. Some individuals are hardly noticeable and do not impact their lives or activities, while others can be very bothersome and cause significant pain. (Scholz C. et al., 2023)

Treatment

Treatment depends on how long the injury has been present and the frequency and severity of the condition.

Clothing Modifications

If the cause is due to tight clothing, belts, or work belts, then garment modification should alleviate symptoms.

Pregnancy

Pregnant women usually find complete relief of their symptoms after delivery. (Hosley, C. M., and McCullough, L. D. 2011)

Weight Loss Program

If recent weight gain is thought to contribute to the condition, then a weight loss program may be recommended.

Cortisone Injections

If simple steps do not relieve symptoms, a cortisone injection around the nerve area may be recommended. The goal is to reduce inflammation that contributes to nerve pressure (Houle S. 2012) . Cortisone injections may be a definitive treatment or a temporary treatment.

Chiropractic

Chiropractic care can be an effective, natural, and safe treatment. Adjustments can help relieve pressure on the lateral femoral cutaneous nerve (LFCN) by realigning the spine and restoring nerve function. Chiropractors may also use soft tissue therapies, such as massage, to relieve muscle tension and support the body’s healing process. Other chiropractic techniques that may be used include:

  • Pelvic mobilizations
  • Myofascial therapy
  • Transverse friction massage
  • Stretching exercises
  • Stabilization exercises for the core and pelvis
  • Therapeutic kinesiology tape

A chiropractic treatment program may include 10–15 treatments over 6–8 weeks, but the number of treatments needed will vary from person to person. If there’s no noticeable progress after 3–4 weeks, it may be time to consult a specialist or surgeon.

Surgery

Surgery is rarely necessary. However, a surgical procedure may be considered when all conservative treatments fail to provide relief. (Schwaiger K. et al., 2018) A surgeon dissects and identifies the nerve, looks for compression locations, and tries to free the nerve from any areas where it may be pinched. Alternatively, some surgeons transect/cut the nerve so it no longer causes problems. If the transection procedure is performed, there will be a permanent area of numbness over the front of the thigh.

Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop a customized treatment plan to relieve pain, treat injuries, improve flexibility, mobility, and agility, and help individuals return to optimal function. If other treatments are needed, Dr. Jimenez has teamed up with top surgeons, clinical specialists, medical researchers, and rehabilitation providers to provide the most effective treatments.

Exploring the Funny Bone: Nerve Injuries and Treatment

Exploring the Funny Bone: Nerve Injuries and Treatment

Can understanding the location of the funny bone and how pain can be managed after injury help expedite recovery and prevention for individuals who have hit their funny bone?

Exploring the Funny Bone: Nerve Injuries and Treatment

Elbow Funny Bone Nerve Injury

Behind the elbow is an area known as the “funny bone,” where the ulnar nerve has less tissue and bone protection. This is where part of the ulnar nerve passes around the back of the elbow. Because less tissue and bone protect the nerve in this area, taking a hit like bumping into something can cause an electric shock-like pain and a tingling sensation down the arm and to the outside fingers typical of an irritated nerve. Most injuries to the funny bone resolve quickly, and the pain disappears after a few seconds or minutes, but sometimes, an ulnar nerve injury can lead to more persistent symptoms.

Anatomy

The funny bone is not a bone but the ulnar nerve. The nerve runs down the arm, passing around the back of the elbow. (Dimitrova, A. et al., 2019) Because the ulnar nerve is on top of the elbow and there is very little fatty cushion, lightly bumping this spot can cause pain and tingling sensations down the forearm. Three bones comprise the junction of the elbow that include:

  • Humerus – arm bone
  • Ulna and radius – forearm bones

The humerus has a groove that protects and holds the ulnar nerve as it passes behind the joint. This is where the nerve can be injured or irritated when the nerve is hit or pinched against the end of the bone, causing the funny bone pain.

Electrical Pain Sensation

When hitting the ulnar nerve or funny bone where the ulnar nerve provides sensation, pain, and electrical/tingling sensations are experienced from the forearm to the outside fingers. This part of the arm and hand is called the ulnar nerve distribution. (American Academy of Orthopaedic Surgeons. 2024) The ulnar nerve provides sensation into most of the pinky finger and about half of the ring finger. Other nerves, including the median and radial nerve, supply sensation to the rest of the hand.

Treatment

Usually, a sharp jolt to the elbow quickly resolves. Some recommendations to help symptoms improve faster include:

  • Shaking the forearm and hand out.
  • Straightening out and bending the elbow to stretch the nerve.
  • Decreasing mobility of the elbow.
  • Applying ice to the area.
  • Taking anti-inflammatory medications.

Treating Long-Lasting Pain

In rare circumstances, injuries to the ulnar nerve can cause more persistent symptoms, a condition known as cubital tunnel syndrome. Cubital tunnel syndrome can happen after an injury or from elbow overuse. Individuals with cubital tunnel syndrome may benefit from wearing a splint at night. Standard-sized splints can be ordered online, but most are fabricated by an occupational or hand therapist. If symptoms become more long-lasting, surgery may be recommended to relieve pressure and tension on the ulnar nerve (American Academy of Orthopaedic Surgeons, 2024). The procedure decompresses the nerve by relieving any tight constrictions around it and releasing them. In severe cases, the nerve is repositioned to an area that doesn’t place as much pressure on the nerve, known as an ulnar nerve transposition.

Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop an optimal health and wellness solution that helps individuals return to normal. Our providers create personalized care plans for each patient, including Functional Medicine, Acupuncture, Electro-Acupuncture, and Sports Medicine principles through an integrated approach to treat injuries and chronic pain syndromes to improve ability through flexibility, mobility, and agility programs to relieve pain. If other treatment is needed, Dr. Jimenez has teamed up with top surgeons, clinical specialists, medical researchers, and rehabilitation providers to provide the most effective treatments.

Neuropathic Gait: An Analysis of Walking Abnormalities

Neuropathic Gait: An Analysis of Walking Abnormalities

Can physical therapies help treat a high steppage gait from injury or medical conditions and restore normal gait patterns for individuals who have or are developing one?

Neuropathic Gait: An Analysis of Walking Abnormalities

Walking or gait anthropometric analysis on a treadmill

Neuropathic Gait

Neuropathic gait, aka equine or high steppage gait, is a type of walking abnormality that causes individuals to raise their hips to lift their legs higher than normal. It occurs when individuals have a foot drop or ankle equinus due to loss of dorsiflexion. As a result, the foot hangs with the toes pointing down, causing the toes to drag while walking. The foot may appear floppy when it drops. Foot drop is caused by weakness or paralysis of the anterior tibialis muscle in front of the shin bone. The anterior tibialis muscle contracts to help flex the foot and ankle while walking, ensuring the foot clears the floor and doesn’t drag. Individuals with anterior tibialis weakness or paralysis may have a neuropathic gait and excessively bend the hip and knee while stepping forward, lifting their leg high off the floor to clear the foot to avoid tripping. A physical therapy team can help with a high steppage gait pattern after illness or injury.

Causes

Conditions that can cause anterior tibialis weakness or paralysis and a high steppage gait pattern include:

Sciatica

Peroneal Nerve Injury

Multiple Sclerosis

Stroke

A primary healthcare provider may refer a physical therapy team to help correct the neuropathic gait pattern.

Treatment

Treatment can involve various therapies that focus on the anterior tibialis muscle.

  • Targeted ankle exercises can help strengthen the muscle.
  • Calf stretches can help maintain the ankle’s range of motion.
  • Gait training exercises.
  • Balance exercises will help improve overall proprioception, or the sense of the body’s position and movement.
  • Neuromuscular electrical stimulation, or NMES, can help improve the function of the muscle. (Hollis, S., McClure, P. 2017)
  • The electrical stimulation artificially contracts the muscle to restore proper function.
  • For anterior tibialis weakness caused by sciatica, back decompression exercises may be prescribed to relieve pressure off the sciatic nerve.
  • The exercises release the nerve to restore normal signal transmission up and down the nerve in the lower back.
  • Neuromuscular electrical stimulation may also be used to help improve muscle function.

Assistive Walking Devices

A therapist may suggest using an assistive device to help the patient walk properly. This could include a wheeled walker or a quad cane. A temporary solution to anterior tibialis weakness is to elevate the foot while walking with an elastic band. Tie a band around the leg below the knee and secure it around the ball of the foot. When swinging the leg forward, the band pulls the foot up. Using it as a temporary solution may help maintain safe mobility. Sometimes, paralysis of the anterior tibialis muscle can become permanent. In this case, individuals may benefit from a special brace called an ankle-foot orthosis. The brace helps to lift the foot and toes off the ground.

For individuals concerned about losing their balance and falling, there are ways to improve walking patterns to stay safe. A healthcare provider may recommend physical therapy to correct gait, strengthen the anterior tibialis muscle, improve balance, and educate on injury prevention. Individuals should discuss symptoms and conditions with a primary physician, healthcare provider, or specialist to guide them in the right direction and determine the best treatment.

Demystifying Spinal Nerve Roots and Their Impact on Health

Demystifying Spinal Nerve Roots and Their Impact on Health

When sciatica or other radiating nerve pain presents, can learning to distinguish between nerve pain and different types of pain help individuals recognize when spinal nerve roots are irritated or compressed or more serious problems that require medical attention?

Demystifying Spinal Nerve Roots and Their Impact on Health

Spinal Nerve Roots and Dermatomes

Spinal conditions such as herniated discs and stenosis can lead to radiating pain that travels down one arm or leg. Other symptoms include weakness, numbness, and/or shooting or burning electrical sensations. The medical term for pinched nerve symptoms is radiculopathy (National Institutes of Health: National Institute of Neurological Disorders and Stroke. 2020). Dermatomes could contribute to irritation in the spinal cord, where the nerve roots cause symptoms in the back and limbs.

Anatomy

The spinal cord has 31 segments.

  • Each segment has nerve roots on the right and left that supply motor and sensory functions to the limbs.
  • The anterior and posterior communicating branches combine to form the spinal nerves that exit the vertebral canal.
  • The 31 spine segments result in 31 spinal nerves.
  • Each one transmits sensory nerve input from a specific skin region on that side and area of the body.
  • These regions are called dermatomes.
  • Except for the first cervical spinal nerve, dermatomes exist for each spinal nerve.
  • The spinal nerves and their associated dermatomes form a network all over the body.

Dermatomes Purpose

Dermatomes are the body/skin areas with sensory input assigned to individual spinal nerves. Each nerve root has an associated dermatome, and various branches supply each dermatome off that single nerve root. Dermatomes are pathways through which sensational information in the skin transmits signals to and from the central nervous system. Sensations that are physically felt, like pressure and temperature, get transmitted to the central nervous system. When a spinal nerve root becomes compressed or irritated, usually because it comes into contact with another structure, it results in radiculopathy. (National Institutes of Health: National Institute of Neurological Disorders and Stroke. 2020).

Radiculopathy

Radiculopathy describes symptoms caused by a pinched nerve along the spine. Symptoms and sensations depend on where the nerve is pinched and the extent of the compression.

Cervical

  • This is a syndrome of pain and/or sensorimotor deficiencies when nerve roots in the neck are compressed.
  • It often presents with pain that goes down one arm.
  • Individuals may also experience electrical sensations like pins and needles, shocks, and burning sensations, as well as motor symptoms like weakness and numbness.

Lumbar

  • This radiculopathy results from compression, inflammation, or injury to a spinal nerve in the lower back.
  • Sensations of pain, numbness, tingling, electrical or burning sensations, and motor symptoms like weakness traveling down one leg are common.

Diagnosis

Part of a radiculopathy physical examination is testing the dermatomes for sensation. The practitioner will use specific manual tests to determine the spinal level from which the symptoms originate. Manual exams are often accompanied by diagnostic imaging tests like MRI, which can show abnormalities in the spinal nerve root. A complete physical examination will determine if the spinal nerve root is the source of the symptoms.

Treating Underlying Causes

Many back disorders can be treated with conservative therapies to provide effective pain relief. For a herniated disk, for example, individuals may be recommended to rest and take a nonsteroidal anti-inflammatory medication. Acupuncture, physical therapy, chiropractic, non-surgical traction, or decompression therapies may also be prescribed. For severe pain, individuals may be offered an epidural steroid injection that can provide pain relief by reducing inflammation. (American Academy of Orthopaedic Surgeons: OrthoInfo. 2022) For spinal stenosis, a provider may first focus on physical therapy to improve overall fitness, strengthen the abdominals and back muscles, and preserve motion in the spine. Pain-relieving medications, including NSAIDs and corticosteroid injections, can reduce inflammation and relieve pain. (American College of Rheumatology. 2023) Physical therapists provide various therapies to decrease symptoms, including manual and mechanical decompression and traction. Surgery may be recommended for cases of radiculopathy that don’t respond to conservative treatments.

Relief from Neurogenic Claudication: Treatment Options

Relief from Neurogenic Claudication: Treatment Options

Individuals experiencing shooting, aching pain in the lower extremities, and intermittent leg pain could be suffering from neurogenic claudication. Can knowing the symptoms help healthcare providers develop an effective treatment plan?

Relief from Neurogenic Claudication: Treatment Options

Neurogenic Claudication

Neurogenic claudication occurs when spinal nerves become compressed in the lumbar or lower spine, causing intermittent leg pain. Compressed nerves in the lumbar spine can cause leg pain and cramps. The pain usually worsens with specific movements or activities like sitting, standing, or bending backward.  It is also known as pseudo-claudication when the space within the lumbar spine narrows. A condition known as lumbar spinal stenosis. However, neurogenic claudication is a syndrome or group of symptoms caused by a pinched spinal nerve, while spinal stenosis describes the narrowing of the spinal passages.

Symptoms

Neurogenic claudication symptoms can include:

  • Leg cramping.
  • Numbness, tingling, or burning sensations.
  • Leg fatigue and weakness.
  • A sensation of heaviness in the leg/s.
  • Sharp, shooting, or aching pain extending into the lower extremities, often in both legs.
  • There may also be pain in the lower back or buttocks.

Neurogenic claudication is different from other types of leg pain, as the pain alternates – ceasing and beginning randomly and worsens with specific movements or activities. Standing, walking, descending stairs, or flexing backward can trigger pain, while sitting, climbing stairs, or leaning forward tends to relieve pain. However, every case is different. Over time, neurogenic claudication can affect mobility as individuals try to avoid activities that cause pain, including exercise, lifting objects, and prolonged walking. In severe cases, neurogenic claudication can make sleeping difficult.

Neurogenic claudication and sciatica are not the same. Neurogenic claudication involves nerve compression in the central canal of the lumbar spine, causing pain in both legs. Sciatica involves compression of nerve roots exiting from the sides of the lumbar spine, causing pain in one leg. (Carlo Ammendolia, 2014)

Causes

With neurogenic claudication, compressed spinal nerves are the underlying cause of the leg pain. In many cases, lumber spinal stenosis – LSS is the cause of pinched nerve. There are two types of lumbar spinal stenosis.

  • Central stenosis is the main cause of neurogenic claudication. With this type, the central canal of the lumbar spine, which houses the spinal cord, narrows, causing pain in both legs.
  • Lumbar spinal stenosis can be acquired and develop later in life due to spine deterioration.
  • Congenital means the individual is born with the condition.
  • Both can lead to neurogenic claudication in different ways.
  • Foramen stenosis is another type of lumbar spinal stenosis that causes the narrowing of spaces on either side of the lumbar spine where nerve roots branch off the spinal cord. The associated pain is different in that it is either in the right or left leg.
  • The pain corresponds to the side of the spinal cord where the nerves are being pinched.

Acquired Lumbar Spinal Stenosis

Lumbar spinal stenosis is usually acquired due to the degeneration of the lumbar spine and tends to affect older adults. The causes of the narrowing can include:

  • Spinal trauma, such as from a vehicle collision, work, or sports injury.
  • Disc herniation.
  • Spinal osteoporosis – wear-and-tear arthritis.
  • Ankylosing spondylitis – a type of inflammatory arthritis that affects the spine.
  • Osteophytes – bone spurs.
  • Spinal tumors – non-cancerous and cancerous tumors.

Congenital Lumbar Spinal Stenosis

Congenital lumbar spinal stenosis means an individual is born with abnormalities of the spine that may not be apparent at birth. Because the space within the spinal canal is already narrow, the spinal cord is vulnerable to any changes as the individual ages. Even individuals with mild arthritis can experience symptoms of neurogenic claudication early on and develop symptoms in their 30s and 40s instead of their 60s and 70s.

Diagnosis

Diagnosis of neurogenic claudication is largely based on the individual’s medical history, physical examination, and imaging. The physical examination and review identify where the pain is presenting and when. The healthcare provider may ask:

  • Is there a history of lower back pain?
  • Is the pain in one leg or both?
  • Is the pain constant?
  • Does the pain come and go?
  • Does the pain get better or worse when standing or sitting?
  • Do movements or activities cause pain symptoms and sensations?
  • Are there any usual sensations while walking?

Treatment

Treatments can consist of physical therapy, spinal steroid injections, and pain meds. Surgery is a last resort when all other therapies are unable to provide effective relief.

Physical Therapy

A treatment plan will involve physical therapy that includes:

  • Daily stretching
  • Strengthening
  • Aerobic exercises
  • This will help improve and stabilize the lower back muscles and correct posture problems.
  • Occupational therapy will recommend activity modifications that cause pain symptoms.
  • This includes proper body mechanics, energy conservation, and recognizing pain signals.
  • Back braces or belts may also be recommended.

Spinal Steroid Injections

Healthcare providers may recommend epidural steroid injections.

  • This delivers a cortisone steroid to the outermost section of the spinal column or the epidural space.
  • Injections can provide pain relief for three months to three years. (Sunil Munakomi et al., 2024)

Pain Meds

Pain medications are used to treat intermittent neurogenic claudication. These include:

  • Over-the-counter analgesics like acetaminophen.
  • Nonsteroidal anti-inflammatory drugs or NSAIDs like ibuprofen or naproxen.
  • Prescription NSAIDs may be prescribed if needed.
  • NSAIDs are used with chronic neurogenic pain and should only be used when required.
  • The long-term use of NSAIDs can increase the risk of stomach ulcers, and the overuse of acetaminophen can lead to liver toxicity and liver failure.

Surgery

If conservative treatments are unable to provide effective relief and mobility and/or quality of life are affected, surgery known as a laminectomy may be recommended to decompress the lumbar spine. The procedure may be performed:

  • Laparoscopically – with small incisions, scopes, and surgical instrumentation.
  • Open surgery – with a scalpel and sutures.
  • During the procedure, facets of the vertebra are partially or completely removed.
  • To provide stability, the bones are sometimes fused with screws, plates, or rods.
  • Success rates for both are more or less the same.
  • Between 85% and 90% of individuals undergoing the surgery achieve long-lasting and/or permanent pain relief. (Xin-Long Ma et al., 2017)
