摘要

摘要髋关节植入物有各种形状和尺寸。本研究旨在选择更好的髋关节植入物柄设计和植入物的最佳材料。在所有材料组合中，每个连接点之间的径向间隙分别为 0、0.1、0.2 和 0.3。使用赫兹接触应力公式进行分析计算，找出 2300N 负荷下的接触压力，这与有限元法（FEM）是相辅相成的。结果表明，钴铬合金柄、股骨头和髋臼杯材料与超高分子量聚乙烯衬垫的最佳组合可实现最有效的性能。这项研究对各种髋关节植入物方案进行了全面评估，并对其有效性提出了重要见解。研究结果将有助于选择最合适的髋关节植入物设计和材料，从而改善患者的治疗效果，推动医疗技术的进步，造福人类。

Computational investigation of various stem designs with different radial clearances in total hip arthroplasty

Abstract Hip implants are available in various shapes and sizes. This study aims to select the better hip implant stem design and the optimal material that can be used for the implant. For all the material combinations, radial clearance of 0, 0.1, 0.2, and 0.3 had been given between each of the junctions. Analytical calculation using Hertz contact stress formulation to find the contact pressure has been employed for a load of 2300N, which goes hand in hand with the Finite element method (FEM). The results showed that the optimal combination consists of a CoCr alloy stem, femoral head, and cup material, paired with a UHMWPE liner, for the most effective performance. This study thoroughly evaluates various hip implant options and offers important insights into their effectiveness. The results of this research will assist in choosing the most appropriate hip implant design and material, leading to better patient outcomes and advancements in medical technology for the betterment of mankind.
