C形臂X线机辅助下L形解剖锁定钢板微创治疗Rüedi-Allgower Ⅱ、Ⅲ型闭合性Pilon骨折的疗效

目的探讨C形臂X线机辅助下L形解剖锁定钢板微创治疗Rüedi-Allgower Ⅱ、Ⅲ型闭合性Pilon骨折的临床疗效。方法在2013-01至2018-12武警第二机动总队医院采用术中分次C形臂X线机透视骨折部位,有限切开组织,骨折复位满意,L形锁定钢板固定良好,微创治疗Rüedi-Allgower Ⅱ、Ⅲ型闭合性Pilon骨折24例患者。结果24例均获得随访,时间6~24个月,平均(15±3.25)个月,骨折愈合佳,无切口感染、血管损伤及踝关节僵硬等并发症;仅有1例出现创伤性关节炎,后经康复治疗1年后恢复正常。根据Mazur踝关节功能评分以及骨折的复位愈合程度评定:优16例,良5例,可3例,优良率为87.5%。结论C形臂X线机辅助下L形锁定钢板微创治疗Rüedi-Allgower Ⅱ、Ⅲ型闭合性Pilon骨折,临床观察,疗效满意。
