Recent studies have shown high early failure rates with Cup Cage constructs in complex revision surgery for Paprosky 3B acetabular defects. As a result, the use of 3D printed custom-made acetabular components has become more common. In this case series, we present two cases that demonstrate the latest advancement in 3D printed implants for severe acetabular bone loss. The follow up was 3 and 7 years. Neither patient has undergone revision surgery of the acetabular component to date. One patient sustained a femoral peri-prosthetic fracture requiring plate fixation. This case study demonstrates that 3D printed implants have excellent intraoperative and immediate postoperative outcomes in revision surgery for severe acetabular bone defects.
近期研究表明，在针对Paprosky 3B型髋臼缺损的复杂翻修手术中，使用髋臼杯笼式假体的早期失败率较高。因此，3D打印定制髋臼组件的应用变得更为普遍。在本病例系列中，我们展示了两例病例，其体现了用于严重髋臼骨丢失的3D打印植入物的最新进展。随访时间分别为3年和7年。截至目前，两名患者均未对髋臼组件进行翻修手术。其中一名患者发生股骨假体周围骨折，需要钢板固定。本病例研究表明，在严重髋臼骨缺损的翻修手术中，3D打印植入物具有出色的术中及术后即刻效果。
