To evaluate the functional and radiological outcome of primary total hip replacement (THR) using modular total hip system at 2-10 years follow-up.
The cohort comprised 100 operated cases for total hip replacement using modular hip system, with an average follow-up of 6.02 years ranging from 2-10 years. In 61 cases cemented THR, in 36 cases hybrid and in three cases uncemented THR was done. Harris hip score was used for clinical evaluation. Osteolysis was recorded in three acetabular zones described by DeLee and Charnley and the seven femoral zones described by Gruen et al.
The average age at operation was 52.46±9.58 years. Mean follow-up duration was 6.02 years ranging from 2-10 years. Four patients died due to causes unrelated to surgery. At the last follow-up mean Harris Hip score was 83.5. Radiolucent lines were present in 39(39%) acetabular and 32 (32%) femoral components. Osteolysis was most common in Zone 7 of the femoral and Zone II and III of the acetabular component. Eight hips have been revised, five for aseptic loosening as proved by negative culture at revision and three hips for posttraumatic periprosthetic femoral fracture. One girdle stone resection was done for deep infection. Out of 96 hips available at latest follow-up, 87 primary arthroplasties were intact and functioning well.
The results of our study support the continued use of the modular hip system. The acetabular loosening was more common than femoral in our study.
评估采用模块化全髋关节系统进行初次全髋关节置换（THR）在2至10年随访期的功能和影像学结果。
该队列包括100例使用模块化髋关节系统进行全髋关节置换的手术病例，平均随访时间为6.02年，范围在2至10年之间。其中61例为骨水泥型THR，36例为混合型，3例为非骨水泥型THR。采用Harris髋关节评分进行临床评估。按照DeLee和Charnley描述的三个髋臼区域以及Gruen等人描述的七个股骨区域记录骨溶解情况。
手术时的平均年龄为52.46±9.58岁。平均随访时长为6.02年，范围在2至10年之间。4例患者因与手术无关的原因死亡。在最后一次随访时，平均Harris髋关节评分为83.5分。39个（39%）髋臼组件和32个（32%）股骨组件出现透光线。骨溶解在股骨的7区以及髋臼组件的II区和III区最为常见。8例髋关节进行了翻修，5例因翻修时培养结果为阴性证明是无菌性松动，3例因创伤后假体周围股骨骨折。1例因深部感染进行了带蒂骨瓣切除术。在最新随访时可评估的96例髋关节中，87例初次关节置换完好且功能良好。
我们的研究结果支持继续使用模块化髋关节系统。在我们的研究中，髋臼松动比股骨松动更常见。
