Methyl methacrylate, used as a grout during hip arthroplasty, can inadvertently become lodged between acetabular and femoral components during surgery. After resumption of ambulation, crescentic fragments may extrude into the pseudocapsule. If mobile methyl methacrylate fragments lodge within the joint, late surgical failure may result because of methyl methacrylate's abrasive character. Two cases of total hip replacement and one case of femoral arthroplasty are reported in which intraarticular methyl methacrylate was identified retrospectively; all three patients remain asymptomatic at the time of the report.
甲基丙烯酸甲酯在髋关节置换术中用作骨水泥，手术过程中可能会意外地滞留在髋臼和股骨部件之间。恢复行走后，新月形碎片可能会挤入假包膜。如果可移动的甲基丙烯酸甲酯碎片滞留在关节内，由于甲基丙烯酸甲酯的磨蚀性，可能会导致晚期手术失败。本文报告了2例全髋关节置换术和1例股骨关节成形术病例，回顾性发现关节内有甲基丙烯酸甲酯；在报告时，所有3例患者均无症状。
