To reduce the risk of injury to the palmar cutaneous branches during open carpal tunnel release, we analyzed the incidence and location of the palmar cutaneous branches along the incision line of classic open carpal tunnel release. Classic skin incision was made on 31 hands of 16 patients. The number and the location of palmar cutaneous branches encountered, were observed under 4x loupe magnification during open carpal tunnel release. No cutaneous nerve branch was found in two hands (6.5%), one branch in 16 hands (51.6%), and two branches in 13 hands (41.9%). In cases of only one branch, it was located averagely 15.6 (range; 7-30) mm from the distal wrist crease. In cases of two branches, the proximal branch was located average 13.2 (range; 7-22) mm from the distal wrist crease, and the distal branch 29.5 (range; 18-43) mm. Palmar cutaneous branches can be encountered with high probability during classic incision of open carpal tunnel release. These results could help to minimize the injury of the palmar cutaneous branches. |
