摘　　要：目的探讨使用Zweymuller螺旋臼假体治疗类风湿关节炎(RA)髋臼骨缺损中股骨头中心性脱位的临床疗效。方法 自2004年6月至2009年10月,26例(27髋)RA髋臼中心性脱位患者,其中男3例(4髋),女23例(23髋),平均年龄52岁(37～62岁),使用螺旋臼治疗,术中有4例行髋臼底部植骨。结果 平均随访6个月～6年3个月,术前Harris评分30.5分,术后平均84分,术后均未发现假体松动,1例出现假体早期感染,予以抗生素治疗6周后好转。结论 RA股骨头中心性脱位使用Zweymuller螺旋臼治疗,可以或不需在臼底植骨,中期稳定性良好。Objective Rheumatoid arthritis （RA） is often associated with intrapelvic protrusion of the femoral head （protrusion acetabuli）. During the operation, the bone grafting and/or cement acetabular prosthesis is usually used to reconstruct acetabular. This paper aimed to discuss using the cementless Zweymuller prosthesis in treatment of protrusion acetabuli. Methods From June 2006 to October 2009, 26 patients （27 hips） were admitted for primary total hip arthroplasty surgeries due to intrapelvic protrusion of the femoral head with RA, including three cases （ four hips ） of male, and 23 cases （ 23 hips ） of female, and the average age was 52 （37 -62 ）. Total hip arthroplasty was performed in all patients using Zweymuller cementless prosthesis, and bone grafting were used in four hips. Results The patients were followed up for 6 mouthes to 6. 4 years. The average Harris hip score was 30. 5 pre-operation and 84 postoperation. There were no loosening in all cases. One case bad infection in early stage, but this patient was doing well after treatment with antibiotics lasting for six weeks. Conclusions Treatment with Zweymuller actebular prosthesis in intrapelvic acetabuli with RA will achieve good result optionally using bone grafting, and satisfactory stability can be achieved in medium-term results.
