A comparison between clinical results and electromyographic analysis after median or ulnar nerve injuries in children's wrists.

Abstract

The purpose of this study was to analyze the results of median or ulnar nerve transections to the wrist in 14 children between 1994 and 1999. On sustaining their injury, all patients underwent treatment at the University Hospital of Nancy. They were all seen afterward for clinical and electromyographic evaluations. The clinical examination was mainly to judge the quality of sensory recovery, using the Weber and Dellon tests, as well as motor recovery. Electromyographic examination of the motor and sensory tissues was carried out systematically on each patient. The analysis of these results highlights discordance between the quality of the clinical results and nerve regrowth identified via electromyography. Good nerve regrowth does not necessarily mean a good sensory recovery.
