The primary aim of this study is to analyse the long-term results of the third generation of the "Zweymüller" total hip arthroplasty (THA) comprising the SL-Plus Stem and the Bicon-Plus cup.
We evaluated 208 patients with a SL/Bicon-Plus primary THA (218 hips). Survival analysis was performed with a follow-up of 13 to 15 years. Complementary clinical and radiological analysis was performed using the "Hip Injury and Osteoarthritis Outcome Score" (HOOS) and x-rays of the hips.
The probability of survival of the stem and cup with revision for any reason was respectively 0.96/0.97 at 10 years and 0.92/0.94 at 15 years. The probability of survival of the stem and cup with revision for aseptic loosening was respectively 0.99/0.97 at 10 years and 0.95/0.94 at 15 years. Clinical assessment of the patients, reported by the HOOS, were scored with a median for the subdivisions: symptoms 90%, pain 93%, function in daily activity 87%, function in leisure or sport 75%, and quality of life with 75%. Periprosthetic radiolucent lines were observed in half of all hips in Gruen zones 1 and 7. Mean linear wear of the polyethylene was 1.8 mm which corresponds to 0.12 mm/year. 2/3 of the hips show heterotopic ossifications, mostly Brooker type 1 and 2.
The "third generation" Zweymüller total hip arthroplasty consisting of the SL stem and the Bicon cup has good long term results in terms of survival, clinical and radiological outcome.
本研究的主要目的是分析第三代“Zweymüller”全髋关节置换术（THA）的长期效果，该置换术包括SL-Plus股骨柄和Bicon-Plus髋臼杯。
我们评估了208例行SL/Bicon-Plus初次全髋关节置换术的患者（218髋）。进行了生存分析，随访时间为13至15年。使用“髋关节损伤和骨关节炎结果评分”（HOOS）和髋关节X线进行补充临床和放射学分析。
股骨柄和髋臼杯因任何原因进行翻修的10年生存率分别为0.96/0.97，15年生存率分别为0.92/0.94。股骨柄和髋臼杯因无菌性松动进行翻修的10年生存率分别为0.99/0.97，15年生存率分别为0.95/0.94。根据HOOS报告的患者临床评估，各亚组的中位数评分如下：症状90%，疼痛93%，日常活动功能87%，休闲或运动功能75%，生活质量75%。在Gruen 1区和7区的所有髋关节中，有一半观察到假体周围透亮线。聚乙烯的平均线性磨损为1.8毫米，相当于每年0.12毫米。2/3的髋关节出现异位骨化，大多为Brooker 1型和2型。
由SL股骨柄和Bicon髋臼杯组成的“第三代”Zweymüller全髋关节置换术在生存率、临床和放射学结果方面具有良好的长期效果。
