    AbstractExtension of the elbow is required to oppose gravity; however, activation of the triceps brachii is frequently underestimated during the surgical planning for brachial plexus injuries. This report aims to describe a novel technique of distal nerve transfer designed for elbow extension reconstruction in patients sustaining a C5-C7 nerve root injury. We report a patient sustaining a brachial plexus injury with triceps palsy and preserved finger extension motion; after careful intraneural dissection of the radial nerve, a fascicle innervating the extensor digitorum communis muscle was sectioned, derouted and connected to a motor branch to the lateral head of the triceps. Eleven months after surgery, elbow extension strength scored MRC M4. No deficits on finger extension were observed.Copyright © 2011 Wiley-Liss, Inc.
