摘要目的 探讨锁定加压钢板(Locking compression plate,LCP)内固定治疗桡骨远端关节内不稳定骨折的方法及其效果.方法 掌侧LCP治疗30例桡骨远端关节内不稳定性骨折(按AO/ASIF桡骨远端骨折分类):B2型6例,B3型7例,C1型7例,C2型8例,C3型2例.结果 随访6～14个月(平均12个月),根据腕关节功能及X线片测量指标进行综合评定,优15例、良10例、可3例、差2例,优良率达83.3％.结论 对桡骨远端关节内不稳定性骨折,掌侧LCP是一种安全有效的治疗方法,根据术中骨折具体情况选择锁定螺钉的植入角度、减少结构性植骨、可有效防止复位丢失、避免肌腱激惹等并发症.

abstractsObjective To explore the method and evaluate the effect of locking compression plate (LCP)fixation of intraarticular unstable distal radial fractures.Methods Thirty patients with intraarficular unstable distal radial fractures were treated with LCP.According to AO/ASIF classification,there were 6 cases of type B2 fractures,7 cases of type B3,7 cases of type C1,8 cases of type C2,2 cases of type C3.Results After 6 to 24 months(average 12 months)following up,there were 15 cases graded as excellent,10 eases as good,3 cases as fair,and 2 cases as poor,according to X ray and wrist function assessment.The overall satisfaction rate was 83.3％.Conclusion Volar LCP fixation is a safe and effective treatment for intraarticular unstable distal radial fractures.It could effectively prevent loss of reduction,avoid tendon irritation and other complications if selecting implant angle for locking screw according to the specific intraoperative circumstances.
