BACKGROUND/AIM: The aim of this study was to analyze survivorship and functional outcome of cementless spongy metal structured total hip arthroplasty (THA) after ultra-long-term follow-up.
PATIENTS AND METHODS
A total of 100 THAs in patients under 65 years at initial surgery were performed between 1985 and 1989 at our Department. Twenty patients (23 hips) were available for final follow-up. Implant survivorship and functional results (Merle d'Aubigné, SF-12) were assessed.
RESULTS
At a mean follow-up of 30 years (range=27.7-31.7 years), the overall stem survival rate was 82.6% (19/23 stems) and the overall cup survival rate was 52.2% (12/23 cups). Revision surgeries were performed for aseptic loosening in all cases. Functional evaluation revealed good to excellent results in 16 patients (80%) Conclusion: Spongy metal structured cementless THA provides remarkable survivorship and excellent functional results even after ultra-long-term follow-up. Further research regarding modern implants, bearing surfaces etc. is required to assess survivorship and clinical outcomes of different implant designs.
背景/目的：本研究的目的是分析超长期随访后无骨水泥多孔金属结构全髋关节置换术（THA）的生存率和功能结果。
患者与方法
1985年至1989年间，我们科室对100例初次手术时年龄在65岁以下的患者进行了全髋关节置换术。20例患者（23髋）可供最终随访。评估了植入物生存率和功能结果（Merle d'Aubigné评分、SF-12评分）。
结果
平均随访30年（范围=27.7 - 31.7年），总体柄生存率为82.6%（19/23柄），总体髋臼生存率为52.2%（12/23髋臼）。所有病例均因无菌性松动进行了翻修手术。功能评估显示16例患者（80%）结果良好至优秀。结论：即使经过超长期随访，多孔金属结构无骨水泥全髋关节置换术仍具有显著的生存率和优异的功能结果。需要对现代植入物、关节面等进行进一步研究，以评估不同植入物设计的生存率和临床结果。
