In this paper we have reviewed the feasibility of using a shock wave lithotripter to loosen the interface between the bone and acrylic bone cement for revision arthroplasty. We have reviewed the physics of shock wave and its applications in medicine, especially its interaction with tissues. The calculations show that the energy is greatly reduced at the interface both in the soft tissue-bone interface and cement-bone interface. On the other hand, a tensile and compressive pressure can be operated at the cement-bone interface that can cause the interface to break if the pressure exceeds the tensile strength of the cement-bone interface. Subsequent papers will deal with in vitro and in vivo application of the shock wave in the treatment of the cement from the intramedullary canal.
在本文中，我们回顾了使用冲击波碎石机来松解骨与丙烯酸骨水泥之间的界面以进行关节置换翻修手术的可行性。我们回顾了冲击波的物理学原理及其在医学中的应用，特别是其与组织的相互作用。计算表明，在软组织 - 骨界面和骨水泥 - 骨界面处，能量在界面处均大幅降低。另一方面，在骨水泥 - 骨界面处可产生拉伸和压缩压力，如果压力超过骨水泥 - 骨界面的拉伸强度，就会导致该界面破裂。后续论文将探讨冲击波在从髓腔内清除骨水泥的治疗中的体外和体内应用。
