title: Evaluation of patients with carpal tunnel syndrome treated by endoscopic technique.
abstract: 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.
  
  
  CONCLUSIONS
  The technique proved to be safe and effective in improving pain, function, and return sensitivity and strength. Level of Evidence II, Prospective study.
