掌侧钢板固定治疗不稳定的背侧移位桡骨远端骨折

Volar LCP fixation for dorsally displaced and unstable distal radial fractures

[目的]初步探讨掌侧钢板（locking compression plate，LCP）固定治疗不稳定、背侧移位桡骨远端骨折的方法及其效果。[方法]回顾性分析掌侧LCP结合克氏针撬拨、植骨等技术治疗不稳定、背侧移位桡骨远端骨折35例，比较研究手术前后掌倾角、尺偏角、桡骨短缩及关节活动范围等，初步评价其临床疗效。[结果]经随访9-24个月（平均17个月），掌倾角、尺偏角、桡骨短缩均获明显改善，腕关节功能按Sarmiento标准评定，优20例、良12例、可2例、差1例。[结论]对不稳定、背侧移位桡骨远端骨折，掌侧LCP是一种安全有效的治疗方法，可有效防止复位丢失、减少结构性植骨、避免肌腱激惹等并发症。

[ Objective] To preliminarily explore the method and evaluate the effect of volar LCP fixation for dorsally displaced and unstable distal radial fractures. [ Method] Thirty-five patients with the fractures were treated with volar LCP combined with the techniques of K-wires and bone grafting, whose effects were evaluated preliminarily through comparing and analyzing the volar tilt, radial inclination, radial shortening and wrist function. [ Result ] Followed up from 9 to 24 months （average 17months）, 20 patients achieved excellent, 12 good and 2 fair with 1 poor, according to Sarmiento scale. [ Conclusion] Volar LCP fixation is a safe and effective treatment for unstable and dorsally displaced distal radial fractures, which could prevent reduction lost, reduce need for bone grafting and avoid tendon irritation.
