Abstract:
PURPOSE: To evaluate the clinical features, results, and prognosis of posterior interosseous nerve injury related to fracture or dislocation of the proximal radius. MATERIALS AND METHODS: From patients with posterior interosseous nerve injury between January, 1985 to December 2002, fourteen patients were selected. There were 2 cases with fracture of the proximal radius alone, 6 cases with fracture of both bones of the forearm, 5 cases with Monteggia fracture, and 1 case of radius head fracture. Eight cases showed nerve injury at the time of trauma, 3 cases after open reduction, and 3 cases after hardware removal. The involved nerve was explored in patients without spontaneous recovery for further treatment. Final range of motion, motor function, and satisfaction were used to assess the results. RESULTS: Seven cases, all with closed fracture, showed spontaneous recovery. The average time of recovery was 6.2 weeks. The remaining 7 cases were treated by neurorraphy (1 case), neurolysis (1 case), sural nerve graft (2 cases), and tendon transfer (3 cases). All cases showed satisfactory results. CONCLUSION: Traumatic posterior interosseous nerve injury rarely happens. Injury after closed fracture usually shows spontaneous recovery. Injury can also take place during open reduction or hardware removal. In cases without spontaneous recovery, The prognosis is generally good after proper treatment.
