We present a technique of femoral impaction grafting used for the treatment of periprosthetic femur fractures with severe bone loss after total hip arthroplasty. Seven patients with femoral fractures with compromise of the femoral isthmus were treated with femoral component revision using the impaction grafting bone technique. The average age was 64 years (range, 44-72 years), and 2 patients required mesh augmentation at the time of surgery. The average follow-up for this group of patients was 56 months (range, 39-92 months). Radiographic evaluation revealed healed fractures in all patients and no evidence of implant loosening at a mean of 56 months (range, 39-92 months). There were no cases of infections or dislocations in this series. Impaction grafting technique can be useful in the treatment of periprosthetic femur fractures when bone loss and canal geometry preclude the use of fully coated femoral components.
我们介绍了一种股骨打压植骨技术,用于治疗全髋关节置换术后股骨假体周围严重骨丢失导致的股骨骨折。7 例股骨干骺端骨折伴股骨峡部骨质缺损的患者采用打压植骨骨技术行股骨假体翻修。患者平均年龄 64 岁(44-72 岁),2 例患者术中需要网片增强。该组患者的平均随访时间为 56 个月(39-92 个月)。所有患者的影像学评估均显示骨折愈合,平均 56 个月(39-92 个月)时无假体松动证据。本系列中无感染或脱位病例。当骨质丢失和髓腔几何形状妨碍使用全涂层股骨假体时,打压植骨技术可用于治疗股骨假体周围骨折。
