Carpal Tunnel Syndrome: a Randomised Controlled Trail of Endoscopic versus Open Release

Aim: The purpose of this study was to compare the results of endoscopic release of carpal tunnel syndrome with the results of the open surgical release technique. Background: The main drawbacks of the open technique of release of carpal tunnel are mainly the hypertrophic and sensitive scar, and the slow post-operative recovery. The endoscopic release of carpal tunnel syndrome reduces pain and scarring, with shortened recovery period. This randomised controlled study was done to evaluate the results of endoscopic 2-portal release technique against the traditional open carpal tunnel release. Methods: A retrospective randomised controlled trial including 122 patients; 62 in the endoscopic group and 60 in the open technique. The mean age was 45.2 years. All procedures were done under regional or general anaesthesia. The operating time was recorded. Patients were evaluated at baseline, 1, 2, 6 weeks and 3 months after surgery. The main outcome was recorded as regards; symptomatic relief, incidence of serious complications (nerve or vascular injury), and pain relief. Duration of complete recovery, scar sensitivity and grip strength were also assessed. Conclusion: With limited benefits of endoscopic release over the open technique as well as lower safety and higher rates of revision, we believe the endoscopic technique offers the patient a less reliable operation.
