Abstract

PURPOSE
The aims of this study were to introduce a new method of percutaneous carpal tunnel release and report its results.
MATERIALS AND METHODS
After preoperative ultrasonographic mapping, a percutaneous carpal tunnel release was performed using the wire rope through two skin needle punctures. Forty wrists of 30 patients were evaluated restrospectively in terms of the symptomatic resolution and complications. The mean age of patients was 53.7 years ranging from 44 to 79 years. The mean follow-up period was 12.8 months ranging from 6 to 18 months.
RESULTS
All cases showed complete relief or marked improvement of symptoms postoperatively. There was no neurovascular injury or other major complication. At postoperative 6 months follow-up, according to the Boston questionnaire, symptom severity score improved from 3.67+/-0.25 preoperatively to 1.55+/-0.33 postoperatively, and functional status score improved from 3.52+/-0.38 preoperatively to 2.09+/-0.42 postoperatively. All patients regained grip strength and pinch strength after surgery.
CONCLUSION
The percutaneous carpal tunnel release using the preoperative ultrasonograhic mapping and the wire rope is an effective, reliable and safe method with the benefits of less postoperative pain and early recovery.
