Abstract:
Although fractures of the radial head traditionally are not associated with healing problems, delayed union and nonunion are being seen more frequently after operative and nonoperative treatment. Given the tenuous blood supply to the head of the radius, problems with healing are not surprising. As the current review of five patients with nonunion of nonoperatively treated radial head fractures treated during a 6-year period shows, healing problems rarely are symptomatic and often may go unrecognized. Even when the fracture still is apparent on radiographs obtained more than 1 year after the injury, healing still may occur. Operative treatment, although rarely necessary, achieved union in one of the current patients.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
