有限切开、撬拨复位、QWIX空心钉内固定治疗后踝骨折

目的 探讨有限切开、撬拨复位、QWIX空心钉内固定治疗后踝骨折的临床疗效.方法 14例后踝骨折患者,男3例,女11例;年龄23～69岁,平均43.6岁.其中交通伤5例,坠落伤4例,行走扭伤3例,滑旱冰扭伤2例.按Weber和Danis踝关节骨折分型方法:A3型2例,B3型7例,C3型5例,进行有限切开撬拨复位QWIX空心钉内固定,并按术后制定的详细的早期功能锻炼和负重时间表,指导患者进行严格规则的功能锻炼,同时定期随访,对踝关节功能恢复情况进行评定.结果 所有患者均获随访,时间6～18个月,平均9.5个月.1例发生腓肠神经损伤,半年恢复正常.12例3个月后步态正常,踝关节活动度接近正常;6个月终末随访时,12例踝关节功能背屈均>20°,跖屈均>40°,与对侧正常踝关节功能大致相同;术后9个月,14例均达到了正常运动功能.临床疗效按Baird-Jackson评分标准:优12例,良1例,可1例,优良率93%.结论 有限切开撬拨复位空心钉治疗后踝骨折是一种行之有效的方法.

Treatment of posterior malleolar fractures by means of limited open reduction, poking reduction and QWIX cannulated screw internal fixation

Objective To evaluate the clinical effect of limited open reduction, poking reduction and QWIX cannulated screw internal fixation in treatment of posterior malleolar fracture. Methods A total of 14 patients with posterior malleolar fracture were treated by limited open reduction, poking reduction and QWIX cannulated screw internal fixation. Injury causes included traffic accidents in five patients, fall from height injury in four and inversion sprain in five. According to fracture type classification methods of Weber and Danis, there were two patients with type A3, seven with type B3 and five with type C3. Func-tional exercise was carried out based on postoperative exercise plan. Regular follow-up was performed to e-valuate the functional recovery of the ankle joint. Results All patients were followed up for 6-18 months (average 9.5 months). One patient with sural nerve injury returned to normal after six months. Twelve pa-tients showed excellent range of motion of the ankle joint and normal gait three months after operation. In 12 patients, dorsiflexion of the ankle joint was > 20° and plantar flexion > 40° six months after operation, which was approximately similar to contralateral normal ankle joint. The ankle joint function of all patients returned to normal six months after operation. According to Baird-Jackson ankle joint function evaluation, the result was excellent in 12 patients, good in one and fair in one, with excellence rate of 93%. Con-clusion The limited open reduction, poking reduction and internal fixation of QWIX caunulated screw are effective method for treatment of posterior malleolar fractures.
