Predicting Healthy C5 Spinal Nerve Stumps Eligible for Grafting with MRI, Tinel Test, and Rhomboid Electromyography: A Retrospective Study of 295 Consecutive Brachial Plexus Surgeries.

MRI had excellent diagnostic accuracy in predicting anatomically healthy C5 spinal nerve stumps in adults with acute brachial plexus injuries preparing for nerve graft microreconstruction.
