Abstract

BACKGROUND Although periprosthetic fractures of the femur are a recognized complication of total hip arthroplasty, periprosthetic fractures of the acetabulum are rare. Simultaneous periprosthetic fractures of both the acetabulum and the femur have not been reported, to our knowledge. CASE REPORT We report a simultaneous fracture of the acetabulum and the femur in a 68-year-old female patient who had previously sustained a subcapital fracture of the femur, treated with a bipolar uncemented prosthesis. We discuss the possible mechanism of this combination of fractures. CONCLUSIONS Simultaneous periprosthetic fractures of the femur and the acetabulum can occur if, in the presence of osteoporotic bone, the metallic femoral head has migrated medially in the acetabulum while the femoral stem is not loose.

摘要

背景

尽管股骨假体周围骨折是全髋关节置换术公认的并发症，但髋臼假体周围骨折却很罕见。据我们所知，髋臼和股骨同时发生假体周围骨折尚未见报道。病例报告：我们报告了一名68岁女性患者髋臼和股骨同时骨折的病例，该患者此前曾发生股骨颈下骨折，采用双极非骨水泥假体治疗。我们讨论了这种骨折组合的可能机制。结论：在骨质疏松的情况下，如果金属股骨头在髋臼内向内侧移位而股骨干未松动，则可能发生股骨和髋臼同时假体周围骨折。
