[Clinical and electroneurographic results following surgery of carpal tunnel syndrome].

The surgical treatment of carpal tunnel syndrome is successful in most cases. Sometimes, however, it is not possible to reach a satisfying result. In order to find out the reasons for failure, we examined 80 surgically treated patients. Clinical and electroneurographical parameters were observed. We could show, that the time of intervention and the age of the patient are responsible for the results. The skin incision has to be planned carefully in order to avoid transection of the palmar cutaneous nerve. In cases of systemic diseases the patient has to be informed preoperatively about the possibility of incomplete recovery.
