When injury is limited to the 5th and 6th cervical roots, and elbow extension and hand function are retained, an "Oberlin" transfer is an excellent option, which avoids the morbidity of having to perform intercostal nerve transfers (see article on this page). The surgery involves transfering 1-2 fascicles from the functioning ulnar nerve to the motor branch to the biceps muscle. The goal is elbow flexion that is strong enough to overcome gravity and perform light lifting. This procedure involves a direct nerve repair very close to the muscle, thus recovery may occur within 4-6 months of surgery.
Successful outcome frees the patient from having to be in a sling for support.When I evaluate your brachial plexus injury in the office, I may need to order additional studies, which, in combination with your physical exam, will allow me to share the potential treatment options with you.
