Reconstruction of finger and elbow function after complete avulsion of the brachial plexus.

Simultaneous reconstruction of elbow and finger function with free muscle and nerve transfers after complete avulsion of the brachial plexus (nerve roots C5 to T1) and its long-term results are presented. The basic procedure combined free or vascular pedicle latissimus dorsi muscle transfer with reinnervation by the spinal accessory nerve to obtain elbow and finger flexion, intercostal nerve transfer of the radial nerve to activate elbow and wrist extensors, and suture of the supraclavicular nerve or intercostal sensory rami to the median nerve to restore hand sensibility. Six patients had some or all of these procedures. Postoperative follow-up ranged from 2 to 5 years. Elbow function was restored completely, and some finger flexion was achieved in all cases, although a dynamic splint was necessary to straighten the digits. Patients have continued to improve in grasp power and finger control. This procedure appears to be promising for the restoration of basic hand function in severely handicapped patients.
