Summary
Conservative therapy for carpal tunnel syndrome offers initial relief for most patients. However, symptom recurrence is common, with only 20% remaining asymptomatic at one year.
Area of Science:
- Orthopedics
- Neurology
- Rehabilitation Medicine
Background:
- Carpal tunnel syndrome (CTS) is a common condition causing hand numbness and tingling.
- Conservative treatments like splinting and corticosteroid injections are frequently used.
- Predicting treatment success in CTS remains a clinical challenge.
Purpose of the Study:
- To identify predictors of successful conservative treatment for carpal tunnel syndrome.
- To evaluate the long-term efficacy of splinting and corticosteroid injections for CTS.
Main Methods:
- Prospective study of 50 hands (34 patients) with carpal CTS.
- Patients aged 25-80 years, with a mean follow-up of 18 months.
- Assessed outcomes of splinting and local corticosteroid injections.
Main Results:
- Initial 8-week conservative therapy success rate was 82%.
- Symptom recurrence led to only 20% remaining asymptomatic at 1 year.
- Predictors of failure included long symptom duration, older age, permanent paresthesia, impaired 2-point discrimination, rapid positive Phalen test, and prolonged distal latencies.
Conclusions:
- Conservative therapy provides temporary relief for many CTS patients.
- Long-term efficacy is limited, with high recurrence rates.
- Several clinical and electrodiagnostic factors predict poor outcomes for conservative management.
