摘要目的 探讨股前外侧皮瓣在Gustilo ⅢB型小腿开放性骨折软组织缺损修复中的应用价值.方法 对GustiloⅢB胫骨骨折合并软组织缺损42例,分别行股前外侧皮瓣急诊修复创面10例,早期修复创面16例和晚期修复创面16例,术后随访,对各组疗效进行分析.结果 移植皮瓣全部成活,无截肢病例,术后随访11～47个月,骨愈合时间6～13个月.和急诊、早期修复组相比,晚期修复组骨折愈合时间延长,骨感染、骨不连发生率明显升高,76%的病例需要行二期骨移植修复骨缺损和骨不连,下肢功能评分低于前两组.结论 对Gustilo Ⅲ B型骨折尽早行创面修复手术,可以缩短治疗周期,改善治疗效果,对严重开放性骨折创伤的治疗有较大临床指导意义.

abstractsObjective To investigate the clinical results of the anterolateral thigh free flaps for the soft tissue coverage of Gustilo grade-Ⅲ B open bone fractures in lower extremities.Methods The anterolateral thigh free flaps were applied to treat 42 Gustilo grade-11Ⅲ B open fractures.Ten flaps were performed through an emergency procedure.Sixteen were performed at early stage and the other 16 were performed at later stage .The results of the therapy were analyzed after long time follow up. Results All limbs were salvaged and all the flaps survived without protracted course to obtain soft tissue coverage.The follow up ranged 11 to 47 months.The healing time of the bones were significant prolonged in the later stage therapy group compared with the emergency therapy group and the early stage therapy group.In the later stage therapy group,the incidences of the bone infection and nonunion were also higher than the other two groups,and the second stage bone transplantation to repair bone defect and nonunion were needed in 76% patients in this group.The lower limb functions of the later stage treated group were worse than those of the other two groups.Compared to the early stage treated group,better lower limb functions could be obtained in the emergency treated group. Conclusion Delayed soft tissue coverage resulted in higher incidence of complications.The immediate soft tissue coverage of severely injured limbs complicated by Gustilo grade-Ⅲ B open fractures and massive soft tissue defects had the advantages over traditional methods.Hard work though it was,one-stage soft tissue coverage using anterolateral thigh free flaps could obtain better lower limb function.
