Carpal tunnel syndrome: postsurgical course of symptoms

The authors analyse the results obtained by the surgical treatment of 113 carpal tunnel syndromes. Performed under locoregional anesthesia, the operation has always been the same: transsection of the volar carpal ligament and epineurolysis on the volar aspect of the median nerve. The results obtained were excellent concerning paresthesia and hypoesthesia. The eventual pejorative influence of three factors, duration of symptoms of more than one year, motor nerve latency over 6 msec., and cyanotic appearance of the nerve, could not be established.
