经皮撬拔复位外固定治疗跟骨骨折疗效观察

Treating Calcaneal Fracture with Percutaneous Reduction by Leverage and External Fixation

目的探讨跟骨骨折手术经皮撬拔复位及外同定的疗效。方法本组56例68足跟骨骨折，受伤至手术时间1～12天，平均7天。骨折按Sanders分类：Ⅱ型38足，Ⅲ型18足，Ⅳ型12足。采用经皮撬拔复位外同定治疗跟骨骨折，手术标准是x线透视下撬拔骨折整复满意与Bohler角和Gissane角满意。结果本组56例68足均得到随访，随访时间平均18个月。按疗效标准评定，优30足，良35足，可3足，无差病例，优良率95．6％。结论经皮撬拔复位外同定治疗跟骨骨折，尤其适用于SanderII型及SanderIII型跟骨骨折，并能恢复Bohler角和Gissane角，疗效满意值得推广。

Objective To discuss the effect of treating calcaneal fracture with percutaneous reduction by leverage and external fixation. Method All 68 calcaneal fractures were included in this group of fifty-six cases, lasting 1 - 12 days （ with an average of 7 days ） before the operations. The fractures were divided according to Sanders classification： 38 type II, 18 typeII and 12 type IV. All patients were treated by percutaneous reduction by leverage and external fixation. The standard of operation was to in spectroscopy confirm the satisfaction of percutaneous reduction by leverage, Bohler angle and the critical angle of Gissane. Results All 68 calcaneal fractures in 56 cases were followed up for 18 months per patient. The results are as follows excellent in30 cases, fair in35 cases, good in 3 cases according to the criterion of therapeutic effect. The rate of being excellent and good was 95.6%. Conclusion Treating calcaneal fracture with percutaneous reduction by leverage and external fixation are propitious to Sanders type II and type III and can recover Bohler angle and the critical angle of Gissane. The reduction and fixation of elasticity are consonant with bone biomechanical philosophy and the results are so satisfying that need effectively recommending.
