Management of comminuted fractures of the distal radius in the adult. Conservative or surgical?

Displaced fractures of the distal radius are difficult to treat successfully by traditional nonoperative methods. The goal in the management of these fractures is to achieve extraarticular alignment and an articular step off of less than 2 mm. Cast immobilization has been supplemented with pins and plaster technique and external fixators. Percutaneous are limited open reduction techniques, combined with wrist arthroscopy, have been shown to be useful in the management of intraarticular distal radius fractures. Despite these advances, there are still a significant number of fractures in which the articular surface cannot be reconstructed without open reduction and internal fixation. The main objective is to restore articular integrity as perfectly as possible. Attention to meticulous surgical technique will facilitate good results. When articular restoration cannot be accomplished, early arthrodesis or arthroplasty should be indicated. In the absence of osteoarthritis, intraarticular osteotomy can be used for intraarticular malunions with a step off greater than 2 mm. Radius malalignment usually requires a dorsal opening wedge osteotomy, insertion of a corticocancellous graft, and a dorsal buttress plate. Early recognition and treatment of distal radioulnar joint injuries associated with fractures of the distal radius are paramount to reduce the incidence of painful sequelae and functional deficits.
