S-ROM股骨柄假体的设计特征与初次全髋置换

Design characteristics of sivash-range of motion femoral stem prosthesis and primary total hip arthroplasty

背景:目前尚缺少S-ROM股骨柄假体应用于初次全髋置换后疗效的报道。目的:探讨S-ROM股骨柄假体在初次全髋置换中的应用。方法:纳入2009-04/2011-05于苏州大学附属第一医院骨科采用S-ROM股骨柄假体行初次全髋置换的71例(75髋)患者,置换后评估髋关节功能及假体的生物学固定效果。结果与结论:纳入的71例患者全髋置换后X射线片显示股骨柄假体的初始固定均符合优良标准。无感染、骨折、脱位、深静脉血栓及神经损伤等并发症。置换后半年,Harris评分恢复至(93.8±3.5)分,X射线片未见假体松动征。说明S-ROM股骨柄假体具有设计合理,可调控性强,符合患者解剖等优点,可有效改善患者髋关节功能。

BACKGROUND：At present,the reports on the application effect of sivash-range of motion（S-ROM） femoral stem prosthesis after total hip arthroplasty（THA） are rare.OBJECTIVE：To discuss the application of S-ROM femoral stem prosthesis in primary THA.METHODS：From April 2009 to May 2011,71 patients（75 hips） were performed primary THA with S-ROM femoral stem prosthesis in the Department of Orthopedic Surgery,the First Affiliated Hospital of Soochow University.The hip functions and the biological fixation effect of the prosthesis were evaluated after the operation.RESULTS AND CONCLUSION：X-ray films of the 71 patients showed the initial fixed stems were in line with good standard.No infection,fracture,dislocation,deep venous thrombosis or neurovascular injury occurred.The mean postoperative Harris hip score was recovered to（93.8±3.5） points at 6 months after surgery.There was no prosthesis loosening.The S-ROM femoral stem prosthesis has the advantages of reasonable design,strong adjustability and in line with patient anatomy,and it can improve the function effectively.
