The aims of this were to examine the effect of acetabular liner exchange and intra-operative bone grafting surgery on peri-prosthetic osteolysis. Seven patients with well-fixed Harris-Galante-1 acetabular components received cemented exchange liners for worn liners associated with pre-operatively CT-quantified osteolysis. During surgery, accessible osteolytic lesions were debrided and bone-grafted. Except for one patient with recurrent dislocation and acetabular component revision, the other patients had CT scans at a median of 4 months and at approximately 4 years after surgery. None of the pre-operative lesions increased in volume during the post-operative reporting period and no new lesions were detected. These results show that cemented liner exchange surgery can halt the progression of osteolysis and that bone grafting has the potential to restore bone.
本研究旨在探讨髋臼内衬更换和术中植骨手术对假体周围骨溶解的影响。7 例 Harris-Galante-1 髋臼组件固定良好的患者因磨损的内衬而接受骨水泥固定的髋臼内衬更换，这些患者术前 CT 定量检查发现有骨溶解。手术中，对可触及的骨溶解病灶进行清创和植骨。除 1 例患者因复发性脱位和髋臼组件翻修外，其余患者术后中位时间 4 个月和大约 4 年后进行 CT 扫描。术后报告期内，无术前病灶体积增加，也未发现新病灶。这些结果表明，骨水泥固定内衬更换手术可以阻止骨溶解的进展，植骨具有恢复骨量的潜力。
