Periprosthetic acetabular fracture is a rare complication after total hip arthroplasty (THA). However, we have treated 2 patients with acute postoperative acetabular discontinuity that occurred 2 and 3 weeks after primary THA. Both fractures were in elderly osteoporotic female patients with minimal trauma and may have developed from unrecognized intraoperative fractures. Pelvic stability was restored with acetabular revision using medial morselized bone grafting and a cemented reconstruction cage. This report demonstrates that early postoperative periprosthetic acetabular discontinuity after THA is a risk in elderly patients with severe osteoporosis and that salvage of acetabular fixation can be achieved with cemented cage reconstruction and medial morselized bone grafting.
人工髋关节置换术后髋关节周围骨折是一种罕见的并发症。然而，我们治疗了 2 例初次 THA 术后 2 周和 3 周后发生的急性术后髋臼连续性中断的患者。这 2 例骨折均发生在轻微创伤的老年骨质疏松女性患者，可能是由于术中未识别的骨折引起的。通过髋臼翻修，使用内侧颗粒状骨移植和骨水泥重建笼恢复了骨盆稳定性。本报告表明，严重骨质疏松的老年患者在 THA 后早期发生术后髋关节周围髋臼连续性中断是一种风险，通过骨水泥重建笼和内侧颗粒状骨移植可以实现髋臼固定的挽救。
