目的 研究经腓骨后外侧入路显露外、后踝骨折,使用抗滑钢板内固定在治疗Lauge-Hansen分型旋后外旋型踝关节骨折中应用效果.方法 2009年1月至2012年12月,对36例Lauge-Hansen分型旋后外旋型Ⅳ型踝关节骨折的患者,经腓骨后外侧入路,显露骨折并用抗滑钢板固定外、后踝.采用Olerud-Molander踝关节功能评分系统评价踝关节术后疗效.结果 所有患者术后随访7 ～ 27个月,平均19个月,无切口感染及皮肤坏死等并发症发生,仅1例发生腓骨肌腱炎,取出钢板后症状缓解.骨折于16周内均愈合.36例中疗效优22例,良9例,可4例,差1例,优良率为86.1％(31/36).结论 经腓骨后外侧入路,应用抗滑钢板治疗外、后踝骨折,可单切口充分显露并固定外、后踝,减少缝合时的张力,提高切口愈合率与骨折稳定性,为踝关节骨折的治疗提供了一个新方法.“,”Objective To study the application effect of antiskid steel plate internal fixation via exposing lateral and posterior ankle fracture through fibula posterolateral approach in the treatment of Lauge-Hansen supination-eversion ankle fracture.Methods From January 2009 to December 2012,exposed the lateral and posterior ankle fracture through fibula posterolateral approach of 36 patients suffering from the Lauge-Hansen supination-eversion ankle fracture,and fixed the lateral and posterior ankle by the antiskid steel plate.Adopt Olerud-Molander ankle function scoring system to evaluate the postoperative effect of the ankle.Results All the patients were followed up for 7-27 months,with an average follow-up of 19 months.There was no complications such as incision infection and cutaneous necrosis.Only 1 patient occurred with peroneus myotenositis,and the symptom was relieved after taking out the steel plate.The fracture was healed within 16 weeks.Among the 36 cases,22 cases were excellent,9 cases were good,4 cases were medium and 1 case was poor.The fine rate was 86.1％(31/36).Conclusion Using the antiskid steel plate to treat the lateral and posterior ankle fracture through fibula posterolateral approach,can fully expose a single incision,fix the lateral and posterior ankle and reduce the tension in suture,improve the incision healing rate and fracture stability,provide a new method for treating ankle fracture.
