This prospective randomized controlled trial evaluated the efficacy of three US-guided hydrodissection techniques for treating carpal tunnel syndrome (CTS) in adults with refractory symptoms. The study found that hydrodissection with normal saline alone led to sustained clinical improvement, with 85.7% of wrists achieving minimal clinically important difference in symptom severity at 24 weeks, comparable to the combination with corticosteroids.
Key findings
- 85.7% of wrists in the hydrodissection group achieved minimal clinically important difference in BCTQ at 24 weeks.
- Percentage reduction in median nerve CSA was 43% for hydrodissection alone and 46% with corticosteroid at 12 weeks.
- Group receiving corticosteroids showed early improvement but no significant difference from baseline at 24 weeks.
- No major complications were observed in any treatment group.
Why it matters
The findings suggest that US-guided hydrodissection with normal saline is an effective treatment for CTS, providing sustained symptom relief without the need for corticosteroids, which may help guide treatment decisions in clinical practice.
