Bone cement (polymethylmethacrylate, PMMA) removal during revision hip arthroplasty can be a tedious, time-consuming process. The usual methods of removing cement include high-speed drills, chisels, saws, and reamers, which are often associated with fracture or perforation of the femoral shaft. An alternative very promising method is cement removal with ultrasound. We present an ultrasonic device for rapid cement removal with minimum risk of trauma to the fragile femoral bone. The technique of cement removal with ultrasound is described and problems and risks are addressed.
髋关节翻修术中骨水泥(聚甲基丙烯酸甲酯,PMMA)的清除可能是一个繁琐、耗时的过程。清除骨水泥的常用方法包括高速钻头、凿子、锯子和铰刀,这些方法常常会导致股骨干骨折或穿孔。一种非常有前景的替代方法是使用超声清除骨水泥。我们展示了一种超声设备,可快速清除骨水泥,同时将对脆弱股骨造成创伤的风险降至最低。本文描述了使用超声清除骨水泥的技术,并探讨了相关问题和风险。
