探讨跟骨骨折术后内翻畸形的原因及对策

Causes analysis and cCountermeasures of varus deformity after calcaneal fracture

目的探讨跟骨骨折术后内翻畸形的原因及对策。方法根据2016-2017年收治的24例跟骨骨折手术患者术后的跟骨侧位、轴位X线片,评估跟骨内翻角,并统计分析。结果该组SandersⅡ型13例,SandersⅢ型9例,SandersⅣ型2例,术后跟骨内翻角(8.29°±5.61°)(1°~22°),其中内翻角度大于8°的有10例,内翻角度为(13.90°±3.84°)(9°~22°)。SandersⅢ型骨折内翻畸形率明显大于SandersⅡ型骨折(P<0.05)。结论术中复位不良及内侧壁支撑不足为跟骨骨折术后内翻畸形的主要原因,术中应注意恢复内侧壁支撑。

Objective To analyze the reason of varus deformity following calcaneal fracture surgery and find out the counter measure.Methods Between 2016 and 2017,24 calcaneal fracture surgery patients were followed up.X-ray of lateral and axial view were taken during the follow-up period.The varus angle was measured via the axial view.Results 13 cases were Sanders II,9 cases were Sanders III and 2 cases were Sanders IV.The varus angle was 8.29°±5.51(arrange from 1°to 22°).The varus angle of 10 cases was bigger than 8°which was 13.90°±3.84(arrange from 9°to 22°).The rate of varus deformity in Sanders III was significant higher than it in Sanders II(P<0.05).Conclusion Poor reductions and inadequate support in the medial wall leaded to calcaneal varus malunion.More attention should be paid to the anatomic reduction and more support for the medial wall.
