Summary
Sonographically-guided intrasheath release for trigger digit (TD) is safe and effective, showing better functional recovery than open surgery. This pilot study confirms the feasibility of a future clinical trial for this minimally invasive technique.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Disorders
- Medical Imaging
Background:
- Classic open surgery and blind percutaneous release for trigger digit (TD) present risks of complications and incomplete results.
- Intrasheath sonographically-guided first annular pulley release offers a potentially safer and more effective alternative.
Purpose of the Study:
- To compare intrasheath sonographically-guided release with classic open surgery for trigger digit.
- To assess the feasibility of conducting a future clinical trial on this technique.
Main Methods:
- A pilot study randomized 30 patients with Grade III trigger digit to either sonographically-guided release (1 mm incision) or classic open surgery (1 cm incision).
- Outcomes included safety, efficacy, recruitment rates, compliance, and QuickDASH scores, with blinded outcome assessment.
Main Results:
- Both techniques achieved symptom resolution without complications.
- The sonographically-guided group demonstrated significantly better QuickDASH scores up to six weeks post-operation.
- Feasibility objectives were met, indicating a future clinical trial with 84 patients is viable.
Conclusions:
- Intrasheath sonographically-guided release is a safe and effective treatment for trigger digit, with a trend towards clinical superiority over open surgery.
- A randomized clinical trial is feasible and recommended to confirm these findings.
