［Objective］To evaluate the biomechanical features of NiTi shape memory alloy stemless femoral prosthesis.

［目的］评价新型记忆合金无柄股骨假体的生物力学特性。

BACKGROUND: Establishment of individual femoral model can describe the stereochemical structure of femoral accurately, which is conductive to measuring femoral anatomic forms. This model possesses unified standard, and removing the potential confounding factors, thus, it is more suitable for biomechanical test.

摘要背景：个体化股骨模型的建立，能够准确、完整地描述出股骨的立体结构，有助于测量股骨的解剖形态，这样的模型有统一的密度和机械性能，去除了个体之间性别、年龄、种族、骨质疏松程度、是否有骨病等混杂因素，用于生物力学测试更有意义。
