The development of ultrasonically driven tools for revision joint arthroplasty is presented. The data represent seven-years' experience and include information from laboratory investigation and clinical experience from 20 surgical cases. Whole bone torsional strength studies reveal no decrease in strength parameters after the removal of cement ultrasonically. Comparison studies demonstrate that ultrasonic tools allow more rapid completion of cement and prosthesis removal than traditional manual tools. Histologic studies using an in vivo canine model demonstrate no deleterious effects to endosteal bone where cement had been removed by ultrasound. Clinical studies indicate that the use of ultrasound facilitates the surgery and causes no cortical perforations; the creation of cortical windows was not necessary in all cases. Ultrasound is safe and efficacious in cement and prosthesis removal during revision surgery.
本文介绍了用于翻修关节置换术的超声驱动工具的研发情况。数据代表了七年的经验，包括来自实验室研究和20例手术病例临床经验的信息。全骨扭转强度研究表明，超声去除骨水泥后，强度参数没有下降。对比研究表明，与传统手动工具相比，超声工具能更快地完成骨水泥和假体的去除。使用体内犬模型的组织学研究表明，超声去除骨水泥对骨内膜没有有害影响。临床研究表明，使用超声有助于手术，且不会导致皮质穿孔；并非所有病例都需要开皮质窗。在翻修手术中，超声在去除骨水泥和假体方面是安全有效的。
