Carpal Tunnel Syndrome

Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy, characterized by the compression of the median nerve as it passes through the carpal tunnel at the wrist. It leads to sensory and motor deficits in the median nerve distribution.

CTS is multifactorial, resulting from elevated pressure within the carpal tunnel.

• Anatomical Factors: Small wrist anatomy, fractures, or dislocations.


• Systemic Conditions: Diabetes mellitus, hypothyroidism, rheumatoid arthritis, obesity, and amyloidosis.


• Physiological States: Pregnancy and menopause (due to fluid retention).


• Occupational/Lifestyle Factors: Repetitive hand movements, prolonged wrist flexion, or exposure to hand-arm vibrations.

The carpal tunnel is a narrow fibro-osseous space bounded by the carpal bones and the transverse carpal ligament. Increased hydrostatic pressure within the tunnel leads to mechanical compression of the median nerve. This compromises microvascular perfusion, causing ischemia, localized demyelination, axonal damage, and perineural fibrosis.

• Prevalence: Affects approximately 1% to 5% of the general population.
• Demographics: Most common in individuals aged 40 to

1. Females are affected 3 times more frequently than males.

• Female sex
• Obesity (BMI > 30)
• Repetitive wrist and hand strain
• Pregnancy
• Rheumatoid arthritis
• Diabetes mellitus
• Hypothyroidism

• Inspection: Atrophy of the thenar eminence in advanced cases.
• Palpation: Normal joint mobility, but possible tenderness over the volar wrist.

• A. Clinical Assessment: Detailed history and provocative testing (Phalen's and Durkan's).
• B. Laboratory Testing: Indicated only to screen for underlying systemic causes (e.g., HbA1c, TSH).
• C. Imaging Studies: High-resolution neuromuscular ultrasound.
• D. Functional Tests: Nerve Conduction Studies (NCS) and Electromyography (EMG) (gold standard for confirming demyelination or axonal loss).
• E. Biopsy Findings: Not clinically indicated.
• F. Genetic Testing: Not applicable.
• G. Differential Diagnosis: Cervical radiculopathy, pronator teres syndrome.

Hemoglobin A1c (HbA1c)

• Type: Blood Test


• Purpose: Screen for undiagnosed diabetes mellitus as an underlying cause of neuropathy.


• Expected Findings: Normal range (<5.7%).


• Interpretation: Elevated levels (>6.5%) suggest diabetic neuropathy co-contributing to CTS. Thyroid Stimulating Hormone (TSH)


• Type: Blood Test


• Purpose: Rule out hypothyroidism-induced myxedematous fluid deposition.


• Expected Findings: Normal range (0.4–4.0 mIU/L).


• Interpretation: Elevated TSH suggests hypothyroidism as a secondary etiology.

Neuromusculoskeletal Ultrasound: Purpose: Visualize median nerve anatomy and rule out space-occupying lesions. Typical Findings: Cross-sectional area of the median nerve at the tunnel inlet >10 mm². Clinical Importance: Confirms physical compression non-invasively.

• Cervical Radiculopathy (C6 Nerve Root): Differentiated by neck pain radiating down the arm, aggravated by neck movement, and sensory loss involving the dorsum of the thumb.
• Pronator Teres Syndrome: Compression of the median nerve in the forearm; characterized by sensory loss over the proximal thenar eminence (palmar cutaneous branch, which bypasses the carpal tunnel).

• Permanent loss of sensation in the median distribution.
• Irreversible thenar muscle weakness and atrophy.
• Complex Regional Pain Syndrome (CRPS) post-surgery.

Conservative therapy resolves mild symptoms in up to 80% of cases. Surgical release provides excellent long-term relief in over 90% of patients, though recovery of severe muscle atrophy may be incomplete.

• Use of nocturnal wrist splints in neutral position.
• Optimizing ergonomic wrist posture at work.
• Management of systemic conditions (diabetes, thyroid disease).
