Background
- Also known as "Median Mononeuropathy"
- Most common focal mononeuropathy
- Results from compression of median nerve at wrist where it traverses the carpal tunnel
- Median nerve provides sensation to the palmar aspect digits 1-3 and radial side of 4th
- Etiology: repetitive wrist flexion/extension, trauma, edema
Risk factors
Clinical Features
History
- Pain, paresthesia, and numbness in distribution of median nerve
- Palmar aspect of thumb, index, middle, and radial aspect of ring finger
- Awakening at night with burning pain and tingling in hand
Physical
- Tinel sign
- Tapping on palmar aspect of wrist reuslts in electric shock sensation shooting into hand
- SN 0.50 and SP 0.77[1]
- Phalen maneuver
- Holding wrists in flexion for 60 seconds evokes or worsens symptoms
- SN 0.68 and SP 0.73[2]
- Durkan sign
- Manual compression of carpal tunnel reproduces symptoms after 30 seconds
- SN 0.64 and SP 0.83
- More sensitive and specific than Tinel and Phalen in earlier studies[3]
Differential Diagnosis
By Type of Lestion
Proximal Lesion
- Spinal cord lesion
- Cervical redicular pain

- Multiple Sclerosis (MS)
Distal Lesion
- Ulna neuropathy
Systemic condition
- Raynaud syndrome
- Pregnancy (Main)
- B12 deficiency
- Diabetic neuropathy
- Hypothyroidism
- Hypocalcemia
Upper extremity peripheral nerve syndromes
Median Nerve Syndromes
Ulnar Nerve Syndromes
Radial Nerve Syndromes
- Radial neuropathy at the spiral groove (ie. "Saturday night palsy")
- Posterior interosseous neuropathy
Proximal Neuropathies
- Suprascapular neuropathy

Other
Evaluation
Management
- See this American Academy of Orthopedic Surgeons clinical decision tool for treatment options and disposition - CTS guidelines
- Behavioral modification
- Wrist splint with wrist in neutral position
- NSAIDs (although not clearly effective)
- Diuretics (if edema is significant contributor to patient's symptoms)
Disposition
Out-patient
