Radial nerve laceration and retraction associated with a supracondylar fracture of the humerus.

Supracondylar fracture of the humerus can be associated with varying degrees of radial nerve injury. Complete laceration of the nerve is rare. We report a case of radial nerve laceration after a supracondylar fracture in which the proximal segment of the nerve retracted into the axilla. Successful treatment resulted from long segmental sural nerve grafting.
