Distal radius fractures with diaphyseal involvement: fixation with fixed angle volar plate

摘要

class="Heading">Background class="Para">The purpose of this study was to evaluate the outcome of fractures of the distal radius with metaphyseal and diaphyseal involvement treated with fixed angle volar plates. class="Heading">Materials and methods class="Para">Twenty-one patients with fracture of the radius involving the diaphyseal, metaphyseal and epiphyseal parts were treated with fixed angle plate fixation through an extended volar Henry’s approach. Circle wire loops, screws and intrafocal wire fixations were associated in 12 cases. Coexisting ulnar fractures were fixed with plates or K-wires in 8 cases. All patients were prospectively followed using radiographs, physical examination, and DASH (Disabilities of the Arm, Shoulder and Hand) scores. class="Heading">Results class="Para">All fractures except one, which needed a secondary bone graft to achieve consolidation, united by an average of 90?days. One case developed a radioulnar synostosis. Radiographs showed optimal reduction in 17 of 21 cases, with restoration of radial length in all cases and a neutral average ulnar variance. Nonanatomical reduction was associated with the worst results (P?=?0.0006). Flexion and extension averaged 62.8° and 73.8°, and pronation and supination 85.2° and 80.2°, respectively. The average DASH scores were 30 points at 3?months, 14 points at 6?months, and 6.7 points at the time of final follow-up (at an average of 11?months). According to the Mayo wrist rating system, 14 patients showed excellent results, 5 showed good results, and 2 showed fair results. class="Heading">Conclusion class="Para">Fixed angle volar plates were demonstrated to be a safe and efficient treatment in these challenging fractures.
