摘要

Purpose To investigate the length gained from subcutaneous and submuscular transposition of the ulnar nerve at the elbow. Specifically, the study aimed to define an expected nerve gap able to be overcome, and to determine if a difference between transposition techniques exists. Methods Eleven cadaveric specimens from the scapula to fingertip were procured. In situ decompression and mobilization of the ulnar nerve at the elbow followed by simulated laceration of the nerve was performed. Nerves were marked 5 mm from the laceration site to facilitate overlap measurement and to simulate nerve end preparation to viable fascicles before primary coaptation. Nerve ends were attached to spring gauges set at 100 g of tension (strain < 10%). Measurements of nerve overlap were obtained in varying degrees of wrist (0°,30°,60°) and elbow (0°,150,300,450,600,90°) flexion. Measurements were performed after in situ decompression and mobilization, and then repeated after both subcutaneous and submuscular transposition.
