Delayed Radial Nerve Palsy After Nonoperative Treatment of Humeral Shaft Fractures: A Report of 2 Cases

CASE Two patients who developed radial nerve palsy at least 6 weeks after injury during nonoperative treatment of humeral shaft fractures. This complication was associated with external bracing, progressive varus angulation during treatment, and excess callus formation. CONCLUSION Delayed radial nerve palsy may develop during nonoperative treatment of humeral shaft fractures when functional bracing fails to maintain alignment and stability at the fracture site.
