Carpal tunnel syndrome is the most common nerve compression syndrome, occurring when the median nerve passing through the carpal tunnel at the wrist comes under pressure. Prevalence in the population is approximately 3-5%. It is more common in keyboard users, manual workers, pregnant women, and patients with diabetes and thyroid disease. Treated early, surgery is unnecessary; in advanced stages, modern surgical techniques yield very successful results.
Symptoms
Typical complaints are progressive and include:
- Numbness, tingling in thumb, index, middle, and radial half of ring finger
- Symptoms that wake from sleep ("relieved by shaking the hand")
- Numbness while driving, holding phone, reading
- In advanced stages, hand weakness, inability to open jars
- In advanced cases, wasting of thumb muscles (thenar atrophy)
- In some patients, pain radiating to arm and shoulder
Diagnostic Methods
Clinical history is the most important diagnostic step. Two classic tests are positive on examination: Tinel test (electric-like sensation toward fingers with tapping over carpal tunnel) and Phalen test (60-second wrist flexion provoking symptoms). For definitive diagnosis and severity assessment, EMG (electromyography) is performed.
Treatment Approach
Non-Surgical Treatments
Conservative treatment can succeed in early and middle stage cases: night splint (keeps wrist in neutral position, provides marked relief in 50-60% of cases), activity modification, ergonomic adjustments, NSAIDs, vitamin B6 supplement. For more resistant cases, cortisone injection into the carpal tunnel can be tried; provides temporary relief in 70% of cases but not a permanent solution.
Surgical Treatment
Surgery is needed for moderate-severe EMG compression, unresponsive to conservative treatment, or with starting muscle wasting. Carpal tunnel release involves cutting the transverse carpal ligament compressing the nerve. Two techniques: open (3-4 cm palmar incision) and endoscopic (1 cm incision with camera). Endoscopic method provides faster recovery.
Surgical Process
Performed under local anesthesia or light sedation. Procedure lasts 15-30 minutes. The patient walks out of the hospital shortly after anesthesia wears off.
Hospital Stay
No hospital stay needed, same-day discharge.
Recovery Process
- First 48 hours: Finger movements free, wrist semi-immobilized
- Week 1: Suture removal, light activities
- Weeks 2-4: Active hand use, physical therapy (if needed)
- Weeks 4-8: Return to full function, grip strength normalizes
- 3-6 months: Palmar tenderness ("pillar pain") fully resolves
Return to Work
Desk work in 3-7 days, light hand-use jobs in 2-3 weeks, heavy hand work in 4-6 weeks.
Potential Complications
Carpal tunnel surgery is one of the safest hand surgeries. Complication rate is below 1%. Rare problems: scar tenderness (usually resolves in 3-6 months), incomplete release, nerve injury (very rare).
Frequently asked questions
Can it heal without surgery?
In early stage cases yes — 50-60% of patients are relieved with night splints, ergonomic adjustments, and injection. However, if EMG shows moderate-severe nerve damage or muscle wasting has begun, surgery is required.
Will my numbness resolve immediately after surgery?
Symptoms that wake from sleep typically disappear even the first night after surgery. Constant numbness improves more slowly proportional to how long the nerve was compressed — sometimes 6-12 months.
Can both hands be done simultaneously?
Usually one hand is operated first; the other is addressed 4-6 weeks later. Because protecting the operated hand requires active use of the other.
