Bony entrapment of ulnar nerve after closed forearm fracture: a case report.
We report a case of ulnar nerve palsy following forearm fracture in a 13-year-old girl. Significant anterior angulation and displacement of the ulna were noted. Operation was performed 3 months after the injury, when no recovery of numbness and claw hand deformity were demonstrated. Intra-operatively the ulnar nerve was found to be embedded between fragments of the fractured ulna, which showed lack of callus formation on the preoperative radiograph. The patient achieved complete recovery of sensory and motor functions 4 months after the surgery.
