Summary
Local corticosteroid injections offer short-term symptom relief for carpal tunnel syndrome (CTS) compared to placebo. However, the duration of benefit beyond one month and comparisons to other treatments remain unclear.
Area of Science:
- Neurology
- Orthopedics
- Rheumatology
Background:
- Carpal tunnel syndrome (CTS) involves median nerve irritation at the wrist.
- Current treatment options include surgical and non-surgical approaches.
- Previous studies on corticosteroid injections for CTS lack robust evidence regarding effectiveness and duration.
Purpose of the Study:
- To assess the efficacy of local steroid injections for carpal tunnel syndrome.
- To compare steroid injections against placebo or other non-surgical treatments.
- To determine the duration of symptom relief following injection.
Main Methods:
- Systematic review of randomized and quasi-randomized controlled trials.
- Searched major databases including Cochrane, MEDLINE, EMBASE, and CINAHL.
- Included studies focused on carpal tunnel syndrome treated with local corticosteroid injection, with clinical improvement as the primary outcome.
Main Results:
- Two randomized controlled trials met the inclusion criteria.
- Local corticosteroid injection demonstrated significant clinical improvement at one month compared to placebo.
- Pooled relative risk favoring treatment was 3.62 (95% CI 1.94 to 6.73).
Conclusions:
- Local corticosteroid injection provides superior clinical improvement for carpal tunnel syndrome symptoms at one month post-injection versus placebo.
- Evidence for symptom relief extending beyond one month is lacking.
- Randomized controlled trials comparing corticosteroid injections to other interventions for CTS are needed.
