[Carpal tunnel syndrome. Can it still be a controversial topic?].

The authors studied two aspects of the carpal tunnel syndrome. As far as the diagnosis is concerned, clinical signs and provocative manoeuvres compared to the accepted standard of electrophysiological studies proved to be insufficient to settle a surgical indication in 85 carpal tunnel syndromes. When surgery is needed, post-operative course is frequently bothered by pillar pain and decreased strength postponing return to manual activities. The authors performed a prospective randomized study of 3 techniques in 251 carpal tunnel releases: classical technique, Agee endoscopic technique and anterior ligamentoplasty. Strength was only improved by the last technique. The only advantage for the endoscopic technique was greater post-operative comfort.
