The use of antibiotic-impregnated acrylic cement as a bone spacer between the intervals of revision hip arthroplasty for infection has been widely practiced. Vascular injuries caused by the migration of a cement spacer with subsequent erosion of the vessel wall have never been reported. A 67-year-old woman presented with tense swelling over her left lower extremity and hemarthroses of the left hip after implantation of a cement spacer for infected hip arthroplasty. Complete external compression of the external iliac vein and laceration of the iliac artery by the spacer were found. The symptoms were resolved after surgical debridement, removal of the spacer and femoral stem, and repair of the vessel. Cautious placement of a cement spacer in the acetabular fossa accompanied with poor bone stock must be emphasized.
抗生素浸渍丙烯酸骨水泥作为感染性髋关节翻修术间隔期骨间隔物的应用已被广泛实践。骨水泥间隔物移位导致血管壁侵蚀引起的血管损伤从未有过报道。一名67岁女性在植入感染性髋关节置换术的骨水泥间隔物后，出现左下肢紧张性肿胀和左髋关节积血。发现骨水泥间隔物对外髂静脉完全外部压迫及髂动脉撕裂。经手术清创、取出间隔物和股骨干并修复血管后，症状得以缓解。必须强调，在髋臼窝骨量不佳的情况下谨慎放置骨水泥间隔物。
