在进行关节成形术之前，必须切割活骨。例如，股骨的远端部分和胫骨的近端部分必须被切割以执行全膝关节置换术。当这种手术中的切割温度超过50摄氏度时，骨细胞开始坏死。在这项研究中，骨内的温度分布的理论计算使用一个线性热源在一个半无限大的平面上移动。此外，使用热成像技术测量了切削刃表面层的温度分布。分析和实验结果表明，切削温度可以估计皮质骨和切削温度突然增加附近的骨表面。因此，如果切割环境不冷却，则表面层0.15 mm内的骨组织的切割温度可能高于35 ℃，因此，骨表面被加热到55 ℃以上。(C)2008年妇女平等问题国际研究所。由爱思唯尔有限公司出版。保留所有权利。
Living bone must be cut before performing arthroplasty. For example, the distal part of the femur and the proximal part of the tibia must be cut to perform total knee arthroplasty. Osteocytes begin to necrose when the cutting temperature during such procedures exceeds 50 degrees C. In this study, the temperature distribution inside bone was calculated theoretically using a linear heat source moving on a semi-infinite plane. Moreover, the temperature distribution on the surface layer of the cutting edge was measured using thermography. Analytical and experimental results showed that the cutting temperature could be estimated for the cortical bone and that the cutting temperature increased suddenly near the surface of bone. Consequently, the cutting temperature of bone tissue within 0.15 mm of the surface layer may be above 35 degrees C if the Cutting environment is not cooled, and consequently, the bone surface is heated to more than 55 degrees C.
