Objective To investigate the surgical technique and efficiency of femoral supracondylar dome osteotomy in treatment of knee valgus deformity.Methods Eight patients with knee valgus deformity underwent femoral supracondylar dome osteotomy.There were 3 males and 5 females with an age of range (14 ～ 35) years.4 cases (left knee) and 4 cases (right knee) with genu valgus,and6 cases with congenital dysplasia and 2 cases with damage were found before surgery.According to Ahlback osteoarthritis staging system,there were 6 knees on stage I and 2 knees on stage Ⅱ,respectively.The femoral supracondylar dome osteotomy combined with internal fixation were applied in patients with valgus knee deformity.All patients were followed up for 2-4 years.Results The valgus knees deformity had been corrected effectively in all cases.Compared with the preoperative X ray film,Complete bone healing was obtained in all patients.The joint function was markedly improved,and the motion of knee joint was good.The subjective satisfaction of patients was good for postoperative status.Conclusion The femoral supracondylar dome osteotomy is a safe,reliable,effective method and strategy for treatment of valgus knee deformity and is worth popularizing,which provide practice reference data for the use of this surgical procedure in clinical.%目的 探讨股骨髁上弧形截骨治疗膝关节外翻畸形的技术和临床效果.方法 选择在文山市人民医院骨二科治疗的8例单侧膝关节外翻患者为实施股骨髁上弧形截骨手术对象.女5例,男3例,年龄14～ 35岁,左侧膝外翻畸形4例,右侧膝外翻畸形4例;先天发育2例,后天形成6例.Ahlback分级:Ⅰ度6例,Ⅱ度2例.采用股骨髁上弧形截骨,克氏针或解剖钢板内固定.所有患者均获随访2～4a.结果 7例优,良1例.与术前相比,所有患者X线片显示截骨端均获得良好骨性愈合,膝关节外翻畸形得到有效矫正,膝关节功能明显改善,膝关节活动良好,主观满意术后状况、感觉良好.结论 股骨髁上弧形截骨术是是一种安全、有效、可靠的治疗膝关节外翻畸形的新策略和方法,值得临床推广应用.
