Article abstract: Introduction & Objective: The anatomical study of the compression site of median nerve in patients with carpal tunnel syndrome can result in to better understanding of carpal tunnel anatomy and the narrowest location of carpal tunnel. This study was performed to have a better understanding of the carpal tunnel anatomy.
Materials & Methods: Forty patients with severe idiopathic carpal tunnel syndrome, who had undergone carpal tunnel release, were entered in this study. The length of compression area in median nerve, the distance between the middle of compression area and distal wrist crease were determined.
Results: From these 40 patients 38 were women and 2 were men. The mean age of these patients was 54± 6.5(37-76) years. The mean length of compression area was 6±1 (3-10) millimeter and the mean distance between the middle of compression area and distal wrist crease was 23±3.5 (18-26) millimeter. This area was adjacent to the hook of the hamate.
Conclusions: According to the results of present study on the anatomy of median nerve in carpal tunnel, the location of the narrowest area and the site with most compression correspond to the location of the hook of the hamate bone.
