What You Should Be Able to Explain After Reading
- Distinguish median nerve compression at the wrist from cervical and proximal nerve problems.
- Use symptom pattern, functional measures and diagnostic uncertainty to plan care.
- Select conservative strategies without promising permanent nerve decompression.
Anatomy and presentation
- The median nerve travels beneath the transverse carpal ligament with nine flexor tendons. Increased pressure within the carpal tunnel can impair nerve function; not every hand tingling complaint is CTS.
- Ask about intermittent thumb, index, middle and radial ring-finger symptoms, nocturnal waking, shaking the hand for relief, repetitive gripping, pregnancy, diabetes and work demands.
History and clinical reasoning
- Map numbness precisely and ask about neck pain, proximal radiation, bilateral symptoms, weakness, fine-motor difficulty and sleep interference.
- Use symptom distribution plus examination rather than relying on one positive provocative test. Consider electrodiagnostic testing when diagnosis is uncertain or severity/surgical decisions require it.
Examination and outcomes
- Examine thumb abduction/opposition strength, thenar bulk, light touch, hand dexterity and wrist/neck movement; document provocative test findings without treating them as definitive.
- Track Boston Carpal Tunnel Questionnaire or QuickDASH, night waking, grip-related function and patient-specific tasks. Repeat measures at planned review.
Differentials and red flags
- C6/C7 radiculopathy, proximal median neuropathy, generalized peripheral neuropathy, ulnar neuropathy and inflammatory arthritis may mimic CTS.
- Persistent sensory loss, progressive thenar weakness/atrophy, major trauma, rapidly progressive neurological symptoms or systemic illness merit timely medical assessment; acute severe pain and swelling require urgent evaluation.
Conservative management
- For mild or intermittent symptoms, discuss neutral-position night splinting and avoiding sustained wrist flexion/extension during sleep or provocative work; fit and tolerance matter.
- Modify gripping, vibration exposure and repetitive loading temporarily while preserving useful hand activity. Explain that injection or surgery decisions belong in shared medical decision-making when appropriate.
- Manual therapy and nerve glides can be considered as symptom-limited adjuncts, but evidence does not justify promising structural release or long-term superiority.
Dose and progression
- A pragmatic trial may use a comfortable neutral night splint for several weeks, with review of adherence, night waking and functional change; the exact duration should follow local guidance and individual response.
- Use short symptom-limited movement breaks and graded return to grip tasks; stop a glide if it provokes lasting paresthesia rather than chasing a strong stretch.
Precautions and common mistakes
- Do not treat worsening weakness with exercises alone or continue a failed conservative plan indefinitely.
- Do not equate a positive Phalen or Tinel test with a confirmed diagnosis; do not claim massage or splinting repairs an injured nerve.
Clinical pearl and summary
- The practical question is not 'Which test is positive?' but 'How confident is the diagnosis, how severe is nerve dysfunction, and is function improving?'. Document a review date and escalation threshold.
