Evaluation of patients with carpal tunnel syndrome treated by endoscopic technique

OBJECTIVE: To evaluate the postoperative results of patients with carpal tunnel syndrome by the endoscopic release technique with single portal. METHODS: 78 patients (80 wrists) were evaluated preoperatively and postoperatively at 1, 3 and 6 months by the Boston questionnaire, the visual analogue scale (VAS) for pain, monofilament test sensitivity, grip strength, lateral pinch, pulp to pulp pinch and tripod pinch. RESULTS: Statistical analysis was significant (p <0.05) in the progressive decline of pain and improved function (Boston) during follow-up. The sensitivity significantly improved comparing the data pre and postoperatively. The grip strength, lateral pinch, pulp to pulp pinch and tripod pinch decreased in the first month after surgery, returning to preoperative values around the third month postoperatively. CONCLUSION: The technique proved to be safe and effective in improving pain, function, and return sensitivity and strength. Level of Evidence II, Prospective study
