Operative treatment of palsy of the posterior interosseous nerve of the forearm.

Abstract

The cases of forty patients who were operated on consecutively for palsy of the posterior interosseous nerve were analyzed. The injury was iatrogenic in sixteen patients, traumatic in fifteen, and nontraumatic in nine. Persistent paralysis (partial or complete) was the only indication for operation. Operative neurolysis was done in twenty-three patients; interfascicular nerve-grafting, in twelve; internal neurolysis, in one; and tendon transfer, in four. An excellent or good functional result was documented for all but three patients, of whom two had had neurolysis and one, nerve-grafting.
