Closed reduction and Kirschner wire and cannulated screws fixation for grade Ⅳ supination-external rotation ankle fractures

目的探讨旋后外旋型Ⅳ度踝关节骨折的微创治疗方法及疗效。方法对22例旋后外旋型Ⅳ度踝关节骨折患者采用闭合复位克氏针及空心钉内固定治疗。结果 18例患者获得随访,时间4~10个月。伤口均一期愈合,无感染。骨折均愈合,无明显疼痛不适。采用AOFAS踝关节-后足评分标准：优12例,良7例,一般3例。结论闭合复位经皮克氏针及空心钉固定治疗旋后外旋型Ⅳ度踝关节骨折,切口小,感染率低,疗效良好。

Objective To investigate the less damage surgical methods and efficacy in treating grade Ⅳ supination-extenal rotation ankle fractures.Methods 22 patients of grade Ⅳ supination-external rotation ankle fractures were treated by closed reduction and Kirschner wire and cannulated screws fixation.Results 18 cases were followed up ranged from 4 to 10 months.The wound got primary healing without infection.All fracture were healed without obvious aching.According to the ankle-hindfoot scale of AOFAS：the results were excellent in 12 cases,good in 7,and fair in 3.Conclusions This method is effective for grade Ⅳ supination-external rotation ankle fractures with small incision,less infection rate and good result.
