[Brachial plexus palsy in adults with radicular lesions, general concepts, diagnostic approach and results ].
In post-traumatic brachial plexus lesions in adults, early repair will necessitate a variety of nerve grafting and nerve transfer procedures. In complete palsies, a graft is performed from a radicular stump, using intercostal nerve transfers, partial cross C7 transfer, and the distal spinal accessory nerve. This will provide elbow flexion and extension in 75% of cases, and shoulder abduction or rotation in 50% of cases. In the upper type palsies, ulnar-biceps transfer is the standard procedure. Grafting from a ruptured cervical root, when available, is performed to reanimate the shoulder. In C5 C6 and C7 palsies, extension of the wrist and fingers is provided by tendon transfers. In chronic palsies, elbow flexion and extension loss is treated by means of free muscle transfers, (latissimus dorsi or gracilis) combined with nerve transfers (intercostals or spinal accessory). Secondary procedures are routinely necessary following recovery of elbow flexion. For the shoulder-humeral shaft osteotomy or fusion, for the hand-cosmetic fusion of the wrist and distal radio-ulnar joint in the prone position, or palliative treatment in case of partial recovery. For such weak "plexic hands", we have developed a specific hierarchical functional scale, useful for surgical decisions.
