[Endoscopic carpal ligament release using the Chow technique: early clinical results].

Abstract

We evaluated the clinical results of endoscopic carpal ligament release in patients with carpal tunnel syndrome. Twenty-six hands of 20 patients (16 females, 4 males; mean age 50 years; range 30 to 65 years) underwent endoscopic carpal ligament release according to the technique described by Chow. Clinical and electromyographic findings were compatible with carpal tunnel syndrome. The mean follow-up period was 13.2 months (range 3 to 28 months). Clinical and electromyographic improvement was obtained in all patients. Complications included superficial wound infection in one patient and neuropraxia of the digital nerve in three patients. The mean time to return to work was 22.5 days. No incision-site pain or localized scar sensitivity were noted. Excellent or good results were achieved in 24 hands (92%). With a good knowledge of endoscopic anatomy and adequate experience, endoscopic carpal ligament release is an appropriate alternative in the treatment of carpal tunnel syndrome, resulting in lower complication rates, early return to daily activities and work, and a lower morbidity.
