    Abstract:
    Anterior and posterior marginal fractures of the distal end of the radius associated with dislocation of the carpus are rare injuries. The results of 20 patients with 12 anterior and eight posterior marginal fracture-dislocations of the distal radius were reviewed. Eleven patients had closed reduction and plaster cast immobilization, including three with external fixation, while nine patients required surgery and internal fixation. At a mean of 3.2 years, 40% were rated as excellent, 45% as good, 5% as fair, and 10% as poor. There was roentgenographic evidence of posttraumatic arthritis in 13 patients (65%). Major factors affecting the clinical results were accurate articular realignment and the presence of ipsilateral carpal injuries. There were no significant differences in results between anterior and posterior marginal fractures or between closed or operative methods of treatment when the radiocarpal articular surface was restored to less than 1 mm residual displacement. Restoration of articular congruency is the primary goal of management of these fractures.
