Acetabular bone loss is not uncommon when performing revision total hip arthroplasty. This can create a challenge, especially on the acetabular side. In the present report, our patient presented with aseptic loosening of the acetabular component. The patient had a Paprosky IIIA acetabular defect that was reconstructed with stacked acetabular augments in addition to a highly porous acetabular cup. The remaining bone defects were addressed through the use of a calcium sulfate/hydroxyapatite bone graft substitute. We set out to describe how to reconstruct severe acetabular bone loss with a combination of acetabular augments in addition to an injectable bone graft substitute as a novel method to address a complex clinical scenario.
在进行髋关节翻修置换手术时，髋臼骨缺损并不罕见。这可能会带来挑战，尤其是在髋臼侧。在本报告中，我们的患者出现了髋臼假体无菌性松动。该患者存在Paprosky IIIA 型髋臼缺损，除了使用高度多孔的髋臼杯外，还采用了堆叠式髋臼增强装置进行重建。其余骨缺损则通过使用硫酸钙/羟基磷灰石骨移植替代物来处理。我们旨在描述如何通过联合使用髋臼增强装置和可注射骨移植替代物来重建严重的髋臼骨缺损，这是一种应对复杂临床情况的新方法。
