摘要
髋关节假体服役过程中会产生高于天然关节的摩擦热,引起假体与滑液温度上升进而改变髋关节假体的松动失效机制.研究摩擦热作用下假体摩擦特性、滑液润滑特性及相关细胞生物学特性,对提高假体体内使用寿命具有重要意义.本文中重点阐述摩擦热对髋关节假体服役寿命影响机制的研究进展,并对其发展趋势进行展望.
Higher frictional heat will be produced during the service process of artificial hip joint prosthesis in vivo than natural joint. The loosening failure mechanism of prosthesis will be changed by the elevated temperature of prosthesis and synovial fluid. In order to improve the service life of prosthesis,it is important to study the frictional characteristics of the prosthesis,the lubrication characteristics of the synovial fluid and the biological characteristics of the related cells under the action of frictional heat. In this review,the latest research progress on the effect of frictional heat on the service life of hip joint prosthesis was summarized. Finally,the development trends were prospected.
