Non-cemented prosthesis should be better for normal bone quality patients because they could reduce stress shielding at greater trochanter and calcar.

骨质疏松者，股骨大转子与股骨矩区域的应力遮挡较大，而在杆端区域的应力集中明显。

The results show that: the input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar; the stress distribution of the femur under external violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.

分析结果表明：股骨颈处的压力骨小梁和股骨距是重要的承载结构，临床医学治疗股骨颈骨折时，内固定物的放置应循压力骨小梁方向并尽量紧贴股骨距钻入；暴力作用时股骨上端的应力分布特点从生物力学的角度说明了老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

Bipolar hemiarthroplasty for intertrochanteric fracture is indicated for patients of more than 80 year old, thus the organic or systemic malfunctions should be corrected during perioperative period. Meanwhile, retaining of lesser trochanter and reconstruction of calcar femorale are of vital importance for improving periprosthetic biomechanics and reducing local complications.

人工股骨双动头置换术治疗股骨转子间骨折适用于80岁以上病人，因此在围手术期应尽可能纠正全身各器官及系统功能异常，同时，保留小粗隆并重建股骨距对改善假体周围生物力学及减少局部并发症具有重要意义。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

On the fracture section, three strain gauges were put above the pins of groups fixed with external fixator. The gauges were recorded when the femurs were loaded vertically. Results (1) The compressive trabeculae and femoral calcar in the femoral neck region are the main load-bearing construction. The contract of the abductor muscle can protect the hip joint. When the model femur was abducted in small degree (10-30°), the stress improved gradually with the abductor angle. But adduction of the model will gradually decrease the stress in that area. When external violence was put on it, the main stress distribution was on the upper femur, which was in the middle and lower part of the femoral neck and between greater trochanter and lesser trochanter.

同时在④⑤两组又应用电阻应变片贴于断端间的三枚斯氏针上方以测定钢针上的应力与应变结果(1)股骨颈处的压力骨小梁和股骨距是重要的承载结构；载荷的传导主要通过压力骨小梁和股骨距由股骨颈区传至股骨干的中下1/3处；外展肌力的收缩对髋关节有一定的保护作用；在小角度外展实验中（10-30°）股骨颈区的应力递增，超过30°时股骨颈区的应力又逐渐减小，但在内收实验中随角度增大股骨颈处应力呈递减趋势；当外界暴力作用时，应力主要集中在股骨上段，即股骨颈中下段和大小转子处及其之间。
