Surgical Technique: Spinal Accessory to Infraspinatus Nerve Transfer in Brachial Plexus Birth Injury.

Nerve transfers, nerve grafts, and tendon transfers have been used to restore shoulder active external rotation in patients with brachial plexus birth injuries. Traditionally used nerve surgery techniques are nerve transfer from the spinal accessory nerve to a suprascapular nerve (SSN) or nerve grafting from C5 to the SSN. However, results are often suboptimal. A more distal and more targeted transfer from the spinal accessory nerve directly to the infraspinatus branch of the SSN has previously been described and mid-term outcomes are encouraging. Herein, we describe a modification of this technique with accompanying step-by-step intraoperative photographs.
