Goubier JN, et al. - For cases where the transfer of the spinal accessory nerve to the suprascapular nerve cannot be performed for the restoration of shoulder external rotation in partial brachial plexus palsies, researchers previously proposed the transfer of the rhomboid nerve to the suprascapular nerve through a posterior approach. In this study, they assessed this technique through a short series. Among eight male patients with a partial plexus palsy, five patients had C5, C6 root injuries, two patients had C5, C6, C7 root injuries, and one patient had C5 to C8 root injuries. C5 or C6 root avulsions were not evident in any of these cases. One patient had the spinal accessory nerve injury and seven patients did not have the proximal suprascapular nerve available. A transfer from the rhomboid nerve to the suprascapular nerve was performed in all patients. Transfers from the branch of the long head of the triceps or ulnar nerve fascicle were transferred to the axillary nerve concerning shoulder elevation. For elbow flexion, they used fascicles from the ulnar nerve, median nerve, or both. For elbow extension, they performed the transfer of three intercostal nerves in one patient and one fascicle from the ulnar nerve in two patients to the branch of the long head of the triceps. Palliative surgery was proposed for wrist and finger extension. Outcomes support the effectiveness of the transfer of the rhomboid nerve to the suprascapular nerve for shoulder external rotation in partial brachial plexus palsies without C5 root avulsion. However, poorer results were obtained in terms of range-of-motion compared with the spinal accessory nerve. Hence, this technique is appropriate in cases with injured spinal accessory nerve or with no available suprascapular nerve in the cervical area. They recommend associating this technique with another transfer to the axillary nerve for shoulder elevation.
