Fractures of the Distal Radius and Ulna: Metaphyseal and Physeal Injuries

Fractures of the distal radius account for 80 percent of pediatric forearm fractures. The rapid growth of the distal radial physis and the on-going transformation of the metaphysic explain the propensity for fractures in this location and the potential for fracture remodeling. Fractures of the distal ulna are less common and usually occur in conjunction with fractures of the distal radius. In general both injuries can be managed by closed treatment and casting. Indications for skeletal fixation and/or open reduction are discussed. Complications are infrequent but not insignificant and usually treatable with early recognition and appropriate intervention.
