摘要

Background: The aim of this study was to compare the functional outcomes and complications of volar and dorsal plating for the management of intra-articular distal radius fractures, with special regard to indications for dorsal plating. Furthermore, we examine the rationale for choosing dorsal plating and its frequency of use. Methods: Clinical assessments included range of motion measurements at the wrist; grip strength; the Quick Disabilities of the Arm, Shoulder, and Hand score; and the Gartland and Werley score. Clinical results were compared with those achieved using a volarly placed locking plate system. According to Lutsky’s plate theory, the rationale for choosing dorsal plating was based on 4 types of pathologic fractures. Results: Of 112 patients, 38 patients were treated with open reduction internal fixation via a dorsal approach and 68 patients were treated using a volar approach. Except for wrist flexion, there were no other statistical differences in the clinical results between groups for both subjective and objective parameters. There were no statistically significant differences in the complication rates between the volar and dorsal plated groups. One serious complication occurred after volar plating. The most common reason for choosing dorsal plating was irreducible dorsal die-punch fractures. Conclusions: The treatment of displaced intra-articular distal radius fractures with a dorsally versus a volarly placed interlocking plate system demonstrated similar clinical results. Postoperative complications were not readily observed in the patients treated with a dorsal locking plate. Certain fracture patterns are more appropriately stabilized using a dorsal plate fixation.
