[Carpal tunnel syndrome: correlation between median nerve relative constriction in the carpal tunnel and distal motor latency].

Purpose: This study analyses the correlation between the constriction in the substance of the median nerve in the carpal tunnel and distal motor latency, gender and age of patients with a carpal tunnel syndrome.

Patients And Methods: In 82 patients (59 women and 23 men with an average age of 66.6 (41-89) years) with an electrophysiologically verified carpal tunnel syndrome undergoing open carpal tunnel release, the diameter of the median nerve was measured at the narrowest point of the nerve at the level of the constriction and the widest point of the nerve proximal to the constriction.
