Taper junctions between modular hip arthroplasty femoral heads and stems fail by wear or corrosion which can be caused by relative motion at their interface. Increasing the assembly force can reduce relative motion and corrosion but may also damage surrounding tissues. The purpose of this study was to determine the effects of increasing the impaction energy and the stiffness of the impactor tool on the stability of the taper junction and on the forces transmitted through the patient's surrounding tissues.

通过无组织损伤的冲击最大限度地提高模块化组件的固定强度。

模块化髋关节置换术股骨头和股骨柄之间的锥形连接会因磨损或腐蚀而失效，这可能是由于其界面处的相对运动引起的。增加装配力可以减少相对运动和腐蚀，但也可能损坏周围组织。本研究的目的是确定增加冲击能量和冲击器工具的刚度对锥形接头稳定性和通过患者周围组织传递的力的影响。
