The anatomy of the carpal tunnel was studied by postmortem dissection of both wrists in ten adults with normal wrists Preoperative clinical and EMG examinations were performed on 28 wrists in 23 patients suffering from carpal tunnel syndrome. Anatomical and histological studies were made in connection with operation, and postoperatively the condition was followed clinically and by EMG. Numbness, tingling, and pain of the hands were markedly relieved during 2 months of follow-up, whereas clumsiness and weakness showed no significant change Preoperatively, EMG showed sensory abnormalities in 96 % of cases and motoric abnormalities in 82 % The diagnostic accuracy of EMG was good, in particular as regards the sensory aspect The return to normal of EMG was slow Pathoanatomical examination showed a normal tendon sheath and transverse carpal ligament in 52 %, while rheuma was found in the specimens of 12 %, fibrosis of the tendon sheath in 36 %, and fibrosis of the transverse carpal ligament in 32 % No correlation was observed between the shape of the osseous carpal tunnel and the degree of clinical symptoms.

Erwachsenen ( 20 Gelenke) mit normalen Handgelenken wurde die Anatomie des Karpaltunnels untersucht Bei 23 Patienten ( 28 Gelenke) mit Karpaltunnelsyndrom wurde praoperativ neben der klinischen Untersuchung ein EMG abgeleitet Anatomische und histologische Studien wurden im Zusammenhang mit der Operation durchgefiihrt, postoperativ erfolgte die Kontrolle des EMG-Befundes Im Ergebnis der Operation waren nach 2 monatiger post-
