Oberlin transfer for C5-6 palsy after posterior cervical spine surgery.

Postoperative C5-6 palsies can occur in 5%-10% of cases after cervical spine surgery. In this video, the authors demonstrate operative techniques for nerve transfer to restore function for postoperative C5-6 palsy. The patient underwent C3-6 laminectomy and posterior fusion for cervical spondylotic myelopathy and developed weakness postoperatively in the C5-6 distribution bilaterally. He experienced spontaneous recovery to near full strength in the most affected muscle groups by 12 months except the left biceps (2/5), with at least antigravity shoulder abduction. He underwent left ulnar to musculocutaneous nerve fascicular transfer to improve elbow flexion and supination in the setting of good hand function.
