Brachial plexus injury.

A 28-year-old man shot himself in the left posterior triangle of the neck with a shotgun. At the initial operation secondary repair of the resultant brachial plexus injury was decided upon in view of the difficulty in assessing lesions in continuity at this point after injury. The patient had total brachial plexus palsy. Nine weeks after the injury sensory and motor function were returning and the only element of the brachial plexus not showing evidence of nerve fibre continuity was the musculocutaneous nerve. Sural nerve autografts were sutured between the trimmed proximal and distal stumps of this nerve. By 4 months after the injury there was further improvement in both sensory and motor function, and by 18 months there was sensation in the autonomous zones of both median and ulnar nerves and good return of muscle power.
