Functional outcomes after open versus endoscopic-assisted De Quervain's release

This study compares outcomes of open vs. single-portal endoscopic release in De Quervain's disease, focusing on functional results and complications.

Forty-four patients diagnosed with De Quervain's syndrome and symptoms persisting longer than 6 months were included. All underwent surgical treatment and were followed for a mean of 41 months (range, 6-120). Patients were divided into two groups based on the surgical method: open (n = 15) and endoscopic (n = 29). Demographic data, preoperative evaluations and hand dominance were recorded. Postoperative functional outcomes were assessed using a visual analogue pain scale, Disabilities of the Arm, Shoulder and Hand score, Mayo wrist score, and grip and pinch strength.

There were no significant differences between the groups in terms of age, sex, dominant hand, affected side, preoperative Finkelstein test results, or previous conservative treatments. Both groups showed significant postoperative improvement in visual analogue pain scale, Disabilities of the Arm, Shoulder and Hand score, and Mayo wrist score. Functional outcomes were similar between the groups. Complication rates were comparable. Median postoperative grip strength was 94% of the healthy side for the endoscopic group compared with 76% for the open surgery group, but the difference was not statistically significant (p = 0.072).

Both open and endoscopic release De Quervain's syndrome produce good results in terms of pain control and functional capacity. Although classical open release is commonly used, the endoscopic-assisted method, which requires experience and learning, can be performed through a smaller incision.
