背景和目的-在过去的十年中，定制的3D打印钛植入物用于重建大型髋臼缺损已被陆续引入。在一项观察性队列研究中，我们评价了术前计划和实际实现的髋臼杯-融合器位置之间的一致性以及髋臼杯-融合器组件的1年随访移位。患者和方法- 10名患有Paprosky III缺陷的患者使用定制的3D打印杯笼进行翻修手术。将术后CT扫描的植入物位置与术前计划进行比较，并将术后CT扫描与1年随访CT扫描进行比较。结果-术后体位与计划的中位偏差为倾斜3.6°（IQR 1.0-5.4），前倾-2.8°（IQR -7.5至1.2），旋转-1.2°（IQR -3.3至0.0）。旋转中心（COR）位置的中位偏差在前后（AP）平面为-0.5 mm（IQR 2.9至0.7），在内外（ML）平面为-0.6 mm（IQR -1.8至-0.1），在上下（SI）平面为1.1 mm（IQR -1.6至2.8）。术后和1年随访之间的移位导致倾斜平均变化0.04°（IQR -0.06至0.09），前倾平均变化-0.13°（IQR -0.23至0.06），旋转平均变化0.05°（IQR -0.46至1.4）。COR在AP平面的移位为-0.08 mm（IQR -0.18至-0.04），在ML平面为0.14 mm（IQR -0.08至0.22），在SI平面为0.06 mm（IQR -0.02至0.35）。没有再次翻修。解释-早期结果显示，在1年随访时，计划和实现的髋臼杯-融合器位置之间具有良好的一致性，并且髋臼杯-融合器组件的测量移位值较小。
Background and purpose — The use of custom-made 3D-printed titanium implants for the reconstruction of large acetabular defects has been successively introduced in the last decade. In an observational cohort study we evaluated the agreement between preoperatively planned and actually achieved cup-cage position as well as 1-year follow-up migration of the cup-cage component. Patients and methods — 10 patients with Paprosky III defects underwent revision surgery using a custom-made 3D-printed cup-cage. The position of the implant on postoperative CT scan was compared with the preoperative plan and the postoperative CT scan was compared with the 1-year follow-up CT scan. Results — There was a median deviation in postoperative position versus planned in inclination of 3.6° (IQR 1.0–5.4), in anteversion of –2.8° (IQR –7.5 to 1.2), and in rotation of –1.2° (IQR –3.3 to 0.0). The median deviation in position of the center of rotation (COR) was –0.5 mm (IQR 2.9 to 0.7) in the anteroposterior (AP) plane, –0.6 mm (IQR –1.8 to –0.1) in the mediolateral (ML) plane, and 1.1 mm (IQR –1.6 to 2.8) in the superoinferior (SI) plane. The migration between postoperative and 1-year follow-up caused a mean change in inclination of 0.04° (IQR –0.06 to 0.09), in anteversion of –0.13° (IQR –0.23 to –0.06), and in rotation of 0.05° (IQR –0.46 to 1.4). The migration of COR was –0.08 mm (IQR –0.18 to –0.04) in the AP plane, 0.14 mm (IQR –0.08 to 0.22) in the ML plane, and 0.06 mm (IQR –0.02 to 0.35) in the SI plane. There was no re-revision. Interpretation — The early results show good agreement between planned and achieved cup-cage position and small measured migration values of the cup-cage component at the 1-year follow-up.
