摘要
目的 :观察环抱器治疗带髓腔内置物股骨骨折的疗效。方法 对 9例带髓腔内置物股骨骨折患者采用切开复位 ,形状记忆锯齿臂环抱内固定器 (简称环抱器 )治疗 ,其中 5例股骨上段带人工股骨假体 ,4例股骨下端带逆行髓内钉。骨折位置分别位于股骨假体柄及尖端周围和髓内钉的尾端。 1例股骨柄松动 ,予全髋翻修结合环抱器固定 ,其余内置物均稳定 ,术后随访 1年。结果 :术后 4月 ,X线片显示大部分骨折获骨性连接 (6/9) ,术后 1年 ,除 1例行全髋翻修加环抱器固定 ,存在髋屈曲受限 (45°)外 ,其余均得到良好的髋膝关节功能恢复 ,无感染、骨不连、再骨折等并发症。结论 :带内置物股骨骨折治疗困难。环抱器内固定提供了一种可靠、经济、实用的治疗选择。
Objective: To observe the clinical outcomes of the embracing fixator for treatment of femoral fracture in the presence of other intramedullary implants.Methods: Shape memory sawteeth-arm embracing internal fixator (simplified as Embracing fixator)was used to treat femoral fractures in the presence of peoximal femoral implants(5 cases)and retrograde supracondylar nail(4 cases).The fracture were around the femoral implants stem or extend just below it and at the proximal end of an retrograde supracondylar nail respectively.All intramedullary implants were well fixed,only one patient had femoral implant loosening,a cementless toatl hip revision was performed for this patient.The follow-up period was one year.Results: Most of the patients(6/9) acheived bony union,as evident radiologically at four months.One year after operation,one patient who has been treated with cementless THR revision combined with embracing fixator had a limited hip flexion(45degrees),the others made a excellent functional recovery of hip and knee joint.No complications were found such as infection,bone nonunion,refracture and so on.Conclusion: The management of femoral fracture in the presence of other intramedullary implants is difficult.The Embracing Fixator provided a reliable,economical,and practical alternative method for treatment of this kind of fracture.
