Tenodesis of extensor digitorum in treatment of brachial plexus injuries involving C5, 6, 7 and 8 nerve roots.

Restoration of motor function in the hand is difficult in brachial plexus injuries in which the C5, 6, 7 and 8 roots are involved, because there are insufficient motors available for transfer to restore the extensors of the fingers and wrist. We have used extensor digitorum tenodesis in 11 cases and found it effective and simple.
