Preoperative and intraoperative electrophysiologic assessment of brachial plexus injuries

Abstract

Preoperative and intraoperative electrophysiologic studies complement one another and complement information obtained from clinical and imaging studies in brachial plexus injury. The information provided by electrodiagnostic studies helps to better define the number, location, and severity of plexus lesions. In addition, establishing the presence or absence of nerve root continuity and early regeneration through postganglionic lesions helps to direct surgical therapy.
