Abstract

Loss of pronation affects most activities of daily living. We report 2 cases of traumatic loss of pronator teres function and successful reconstruction by transfer of a redundant motor branch to the flexor digitorum superficialis to the pronator teres branch(es). Follow-up period was 2 years and pronation strength was restored to +4/5 and 5/5 in the 2 patients. The anatomy of the median nerve in the proximal forearm was examined by dissecting 31 cadaver specimens. A branching scheme was formulated. The histomorphometric properties of the individual muscular branches were studied in 15 fresh specimens to evaluate their suitability and size match for nerve transfer.
