Quantitative information regarding the interface strength and degree of cement penetration associated with cement viscosity during total hip arthroplasty is limited. The aim of the present study was to determine the effect of the viscosity of bone cement at the time of implantation on the mechanical integrity of total hip arthroplasty. Cement that was injected at an early less viscous stage produced greater failure strength in a push-out test than its more viscous counterpart.
关于全髋关节置换术中骨水泥粘度与界面强度及骨水泥渗透程度的定量信息有限。本研究的目的是确定植入时骨水泥粘度对全髋关节置换术机械完整性的影响。在早期粘度较低阶段注入的骨水泥在推出试验中产生的破坏强度高于粘度较高的骨水泥。
