Abstract
OBJECTIVE
The purpose of this study was to evaluate the efficacy and functional outcomes of limited mini-open carpal tunnel release and to describe the technique.
METHODS
Twenty-nine patients(33 hands) underwent limited mini-open carpal tunnel release with a 1.5~2cm incision. The postoperative evaluations consisted of determination of symptom relief and assessment of the subjective complaints of scar hypersensitivity and tenderness.The patients had functional evaluations using grip and key pinch strength and the Michigan Hand Outcome Questionnaire(MHQ). The evaluations were performed before the operation as well as 3 weeks and 6months after surgery.
RESULTS
Most patients(31/33) had complete resolution of their symptoms during the immediate postoperative period. Twenty-four patients(83%) reported mild to moderate incision tenderness 3weeks after the operation. No patient reported scar tenderness 6 months after the procedure during follow-up. No statistically significant difference in either grip strength or key pinch was observed between the preoperative period and 6 months postoperatively. There were significant postoperative improvements in hand function as evaluated by the MHQ, compared with the preoperative findings.
CONCLUSION
The limited mini-open carpal tunnel release via a small palmar incision is a technically simple and effective procedure that preserves most structures necessary for a rapid postoperative recovery. This approach allows significant symptom relief, minimal scar tenderness, and significant improvement in overall hand function.
