title: Malunion of the distal radius.
abstract: Fractures of the distal radius are common injuries. Acceptable results typically can be obtained with appropriate surgical or nonsurgical management. However, a small percentage of these fractures can progress to symptomatic malunion, which traditionally has been treated with osteotomy of the distal radius. Proper understanding of anatomy, biomechanics, indications, and contraindications can help guide patient selection for surgery. In formulating a treatment plan, the surgeon also must consider such technical variables as the type of osteotomy, the use of bone graft or bone-graft substitute, and the means of fixation to stabilize the osteotomy. Simultaneous implementation of an ulnar-side procedure, an intra-articular osteotomy, and soft-tissue releases also may be necessary. Some cases may be more appropriate for wrist fusion or other salvage procedures.
