Nerve Compression Syndrome

Nerve compression syndrome—also known as entrapment neuropathy or compression neuropathy—is a condition in which chronic pressure on a peripheral nerve leads to pain, numbness, tingling, and muscle weakness in the area supplied by that nerve. Over time, untreated compression can cause permanent nerve damage, making early recognition and a comprehensive treatment plan essential en.wikipedia.org.

Nerve compression syndrome occurs when surrounding tissues—such as bones, muscles, tendons, or ligaments—apply excessive pressure on a nerve. This pressure disrupts the normal function of the nerve, leading to a spectrum of symptoms that can range from mild tingling to severe pain and muscle weakness. Often referred to by more specific names—like carpal tunnel syndrome or cubital tunnel syndrome—nerve compression syndromes share common underlying mechanisms: reduced blood flow to the nerve, impaired nerve fiber transmission, and local inflammation. Over time, if left untreated, chronic compression can cause permanent nerve damage and lasting disability. Understanding nerve compression syndromes demands a clear grasp of their anatomy, pathophysiology, and clinical presentation to guide timely diagnosis and effective management.

The most common examples include carpal tunnel syndrome (median nerve at the wrist), cubital tunnel syndrome (ulnar nerve at the elbow), tarsal tunnel syndrome (posterior tibial nerve at the ankle), and radial tunnel syndrome (radial nerve in the forearm). However, any nerve running close to a rigid structure—bone, ligament, muscle, or fibrous tissue—can be affected en.wikipedia.org.

This article provides a 360° view of nerve compression syndrome, from anatomy and pathophysiology through a vast array of treatments—conservative to surgical—to prevention and lifestyle strategies, equipping you with the knowledge to manage or prevent this debilitating condition.

Pathophysiology

When external forces compress a nerve, blood flow within the nerve’s microvasculature is reduced. This ischemia impairs Schwann cell function and axonal transport, leading to demyelination and, eventually, axonal degeneration if unrelieved. The result is the classic triad of pain, paresthesia (pins-and-needles), and weakness in the nerve’s distribution. Chronic compression triggers inflammation and fibrosis around the nerve, perpetuating a cycle of injury and repair that can culminate in permanent damage without timely intervention en.wikipedia.org.

Types of Nerve Compression Syndromes

1. Carpal Tunnel Syndrome
   Compression of the median nerve as it passes through the carpal tunnel in the wrist. Common in people who perform repetitive hand motions.

2. Cubital Tunnel Syndrome
   Pressure on the ulnar nerve at the elbow, often from leaning on the elbow or prolonged flexion.

3. Thoracic Outlet Syndrome
   Involves compression of nerves (and sometimes blood vessels) between the collarbone and first rib, leading to shoulder and arm symptoms.

4. Radial Tunnel Syndrome
   Occurs when the radial nerve is compressed near the elbow, leading to forearm pain and sometimes wrist drop.

5. Tarsal Tunnel Syndrome
   Compression of the posterior tibial nerve as it travels through the tarsal tunnel in the ankle, causing foot pain and numbness.

6. Guyon’s Canal Syndrome
   Ulnar nerve compression at the wrist in Guyon’s canal, leading to hand pain and finger weakness.

7. Meralgia Paresthetica
   Compression of the lateral femoral cutaneous nerve in the thigh, causing burning sensations and numbness.

8. Piriformis Syndrome
   The sciatic nerve is compressed by the piriformis muscle in the buttock, causing sciatica-like pain.

Causes of Nerve Compression Syndrome

1. Repetitive Motion
   Performing the same movement repeatedly—such as typing or assembly-line work—can inflame surrounding tissues and pinch a nerve over time.

2. Direct Trauma
   A sudden blow or injury near a nerve can cause swelling and scarring, leading to compression.

3. Poor Posture
   Slouching or keeping joints in awkward positions for long periods increases pressure on nerves, especially in the neck and back.

4. Obesity
   Excess body weight can cause additional soft tissue around nerves, reducing available space and increasing compression risk.

5. Pregnancy
   Fluid retention and hormonal changes during pregnancy can enlarge tissues and compress nerves, most often in the wrist.

6. Arthritis
   Degenerative joint changes, bone spurs, or inflamed synovium can encroach on nerve pathways, causing compression.

7. Diabetes
   High blood sugar levels can damage nerves (diabetic neuropathy), making them more susceptible to pressure-related injury.

8. Thyroid Disorders
   Hypothyroidism can cause mucopolysaccharide deposition in tissues, narrowing nerve tunnels such as the carpal tunnel.

9. Tumors
   Both benign and malignant growths near nerves can physically compress them, disrupting normal function.

10. Cysts and Ganglions
    Fluid-filled sacs that develop along tendons or joints may press on nearby nerves.

11. Edema
    Generalized swelling—due to heart failure, kidney disease, or injury—can reduce the space around nerves.

12. Bone Fractures or Dislocations
    Misaligned bones or joint dislocations can pinch nerves either immediately or as they heal.

13. Tight Clothing or Accessories
    Wearing rigid braces, tight straps, or certain types of footwear can constrict nerves in limbs.

14. Tumefactive Multiple Sclerosis
    Plaques or lesions in MS can create focal swelling and pressure on nerves within the central or peripheral nervous system.

15. Infection
    Local infections—such as cellulitis or abscesses—can produce inflammation, swelling, and nerve compression.

16. Radiation Therapy
    Fibrosis and tissue scarring following radiation can constrict nerve pathways months to years later.

17. Amyloidosis
    Deposition of amyloid proteins in tissues can narrow nerve tunnels and compress nerves.

18. Vitamin Deficiencies
    Lack of vitamins B6 or B12 can lead to nerve swelling and increased vulnerability to compression.

19. Genetic Predisposition
    Some individuals have anatomically narrower nerve tunnels or connective tissue variations that predispose them to compression.

20. Occupational Hazards
    Jobs requiring heavy lifting, continuous vibration exposure (e.g., jackhammer use), or prolonged static postures raise risk of nerve compression.
