Strangulation of Radial Nerve Within Nondisplaced Fracture Component of Humeral Shaft Fracture.

Rates of radial nerve injury, which is commonly associated with humeral shaft fractures, range from 8% to 12%. This neurapraxia typically recovers with nonoperative management. In some conservatively treated cases, the radial nerve is lacerated or entrapped. Patients with a lacerated or entrapped nerve may have better outcomes with early operative management. We report on a rare case of the radial nerve entrapped within a nondisplaced segment of a closed humeral shaft fracture and describe the clinical outcome of early operative management.
