Fifty rats in the model group underwent ovariectomy, while the other 20 rats in the control group had sham operations. Three months later, 10 rats in the model group and 10 rats in the control group were selected randomly to detect their body weight, uterus weight, BMD of the left femur and lumbar vertebra, biomechanical characteristics of the left femur, levels of serum Ca2 +, Cr, ALP, SOD, MDA and GSH-Px and serumal resistance to OH(superscript -).

［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。

STDSP may be a better internal fixation with good biomechanical feature to the treatment of subtrochanteric femoral fracture.

初步认为STDSP是一种具有较好生物力学性能的治疗股骨转子下骨折的内固定器械。

Methods: Three out of eight pelvic specimens of cadavers were measured as normal group. then vertically unstable pelvic fractures were produced, and the biomechanical stiffness of internal fixation by sacroiliac screws with four hole LCDC symphyseal plates was tested and compared in the different reductions placement (low displace group and high displace group), the vertical and horizontal displacements of the sacroiliac joint and pubic symphysis were measured.
