In the antero-posterior X- ray film ,the position of the lag screw should be parallel to the long axis of the neck of femur, slightly above the level of the femoral calcar.

认为加压螺钉的位置应是在正位平行于股骨颈的长轴，位于股骨距稍上的水平，侧位位于股骨颈的中轴线上。

Collared device for reducing stress shielding of calcar should be recommended for osteoporosis patients.

因此，骨质正常者应该选用非骨水泥假体，以减少大转子与股骨矩区域的应力遮挡；而骨质疏松者最好选用有肩托的假体，以减少股骨矩处的应力遮挡作用。

The rationale for an inferior screw close to the calcar is that the inferior cortex can act as a buttress for an adjacent screw if good screw purchase in the femoral head is obtained.

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。

Femoral neck fracture calcar femoral fracture fixation , internal CEPS

股骨颈骨折，股骨距，骨折固定术，内

The lower von Mises stress in the calcar region was found at the stovepipe models with a low flare stem (8.78MPa for thick and 8.23MPa for thin cement technique).

在同组模型之股骨calcar 之von Mises 应平均较低（厚骨水8.78MPa 和薄骨水8.23MPa 。

Results: The BMD decreased fastest in the first year after operation, as the postoperative time prolonged, the BMD decreased markedly at the medial part of the stem especially at the calcar and under calcar part, and at the medial part of the stem and the large trochanter, the BMD at the lateral lower part of the stem decreased at a lower extent, the femur shaft part under the tip of the stem lost the lest bone.

结果：术后第一年骨丢失多，随术后时间延长，假体柄内侧尤其是股骨矩及矩下R7、R6区、假体尖内侧R5和大粗隆区R1区骨丢失最明显，假体柄外侧中、下R2、3区端次之，假体柄尖远端股骨干处R4区骨丢失相对较少。
