Transfer of the intercostal nerves to the nerve of the long head of the triceps to recover elbow extension in brachial plexus palsy.
Restoration of elbow flexion is the first goal in brachial plexus injuries. The current procedures using nerve grafts and nerve transfers authorize more extensive repairs, with different possible targets: shoulder, elbow extension, and hand. Elbow extension is important to stabilize the elbow without the contralateral hand and allows achieving a useful grasp. The transfer of the intercostal nerves to the nerve of the long head of the triceps may restore this function in brachial plexus palsies. Furthermore, in case of C5 to C7 palsy, this transfer spares the radial nerve and gives a chance to spontaneous triceps recovery by the reinnervation from C8 root. Moreover, in case of absence or insufficient (M0 to M2 according to Medical Research Council scoring) recovery of elbow flexion strength by nerve surgery, the reinnervated triceps can be transferred. We present the technique of intercostal nerve transfer to the long head of the triceps branch to restore elbow extension in brachial plexus palsy. Results concerning 10 patients are presented.
