Total hip arthroplasty (THA) remains the standard treatment for advanced osteoarthritis, including for complex deformities. Innovations such as spherical screw-in acetabular components aim to enhance fixation and long-term outcomes. This study evaluated the long-term clinical and radiographic outcomes of cementless THA using such implants. A retrospective analysis was conducted on 277 patients (293 hips) who underwent THA with a screw-in acetabular cup (Aesculap/BBraun SC, Tuttlingen, Germany) and Antega femoral stem between 2005 and 2024. Patients were evaluated using the modified Merle d'Aubigné and Postel (MAP) score, Visual Analog Scale (VAS), and radiographic classifications, with implant survival assessed via Kaplan-Meier analysis. The mean follow-up was 13.8 years. At the final follow-up, 58.7% of hips achieved excellent MAP scores, and mean VAS pain scores improved from 7.1 to 1.8 ( < 0.05). Implant positioning was within the Lewinnek safe zone in 77.1% of cases. Revision was required in 6.1% of hips, mostly due to aseptic loosening. The five- and ten-year survival rates were 98.3% and 94.0%, respectively. Spherical screw-in acetabular cups provide durable fixation and satisfactory long-term outcomes in THA, particularly for dysplastic hips, supporting their continued use with careful surgical techniques.
全髋关节置换术（THA）仍然是晚期骨关节炎（包括复杂畸形）的标准治疗方法。球形拧入式髋臼组件等创新旨在增强固定效果和长期疗效。本研究评估了使用此类植入物的非骨水泥型THA的长期临床和影像学结果。对2005年至2024年间接受THA手术、使用拧入式髋臼杯（德国图特林根的蛇牌/贝朗SC）和安特加股骨柄的277例患者（293髋）进行了回顾性分析。使用改良的Merle d'Aubigné和Postel（MAP）评分、视觉模拟量表（VAS）以及影像学分类对患者进行评估，并通过Kaplan-Meier分析评估植入物的生存率。平均随访时间为13.8年。在最后一次随访时，58.7%的髋关节获得了优异的MAP评分，VAS疼痛评分均值从7.1改善至1.8（<0.05）。77.1%的病例中植入物位置处于Lewinnek安全区内。6.1%的髋关节需要翻修，主要原因是无菌性松动。五年和十年生存率分别为98.3%和94.0%。球形拧入式髋臼杯在THA中提供了持久的固定效果和令人满意的长期疗效，特别是对于发育不良的髋关节，支持在采用谨慎手术技术的情况下继续使用。
