The authors present a prospective study comparing two surgical techniques for carpal tunnel release. A minimal - incision open decompression(3) is compared with an endoscopic release(2), that utilizes only a single proximal portal. There were operated on, 28 wrists in 28 patients, with clinical signs and EMG changes consistent on idiopathic carpal tunnel syndrome, that failed under previous conservative treatment. They were randomized into two groups , undertaken surgical treatment, either by endoscopic release or by open decompression. Grip strength (measured by dynamometric), sensitivity (measured by Semmes-Weinstein monofilaments), presence of pain and paresthesia, date of return to activities of daily living and complications were evaluated pre-operative and at 1, 2, 4, 6, 12 weeks after surgery. After 12 months average follow up, the results indicated that this proximal portal endoscopic technique can be safely performed, showing advantages over open conventional method, in terms of sooner return of grip strength, date of return to activities of daily living, and less incidence of pillar pain. No differences in paresthesia resolution, sensibility improvement or complications incidence were found.
