The combined anteversion technique has been proposed recently and proved to be an applicable technique in general THA. The corresponding author routinely applied this approach to DDH patients in clinical practice. The current study aimed to provide clinical evidence for this approach. We studied 35 DDH patients (47 hips). Every patient underwent pelvic CT scans before and after surgery and the HHs was recorded. The data indicate a high accuracy of controlling components orientation and satisfactory clinical outcomes. Using this approach, we reduced dislocation risk and got better impingement free range of motion. Therefore, we conclude that combined anteversion is effective for DDH patients who receive a THA. This approach could guarantee stable and functioning joints for DDH patients receiving THA.
联合前倾技术最近已被提出，并被证明是全髋关节置换术（THA）中一种可行的技术。通讯作者在临床实践中常规地将这种方法应用于发育性髋关节发育不良（DDH）患者。本研究旨在为这种方法提供临床证据。我们研究了35例DDH患者（47髋）。每位患者在手术前后均接受了骨盆CT扫描，并记录了髋关节中心边缘角（HHs）。数据表明，该方法在控制假体组件方向方面具有很高的准确性，并取得了令人满意的临床效果。使用这种方法，我们降低了脱位风险，并获得了更好的无撞击活动范围。因此，我们得出结论，联合前倾对于接受THA的DDH患者是有效的。这种方法可以为接受THA的DDH患者保证关节的稳定和功能。
