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。

Thirty cadaveric femurs were randomly allocated into five groups, each with 6 femurs. An osteotomy was made (Pauwels angle 70°) in the middle of the femoral neck. Then each group was fixed using one of these methods:①Dynamic Hip Screw ;②Three 4mm Steinn Pins that placed in accordance with the compressive trabeculae and clingy to the femoral calcar ;③One compressive screw;④Low angle fixation of external fixator;⑤High angle fixation of external fixator.

3取经防腐处理的人尸体股骨30具，随机分成5组，每组6具，在股骨颈中部按Pauwels角70度锯断，每组分别以以下方法固定：①动力髋螺钉固定；②三枚4mm斯氏针按本文第一、第二部分分析出的股骨的主应力方向（按压力骨小梁方向紧贴股骨距低角度倒三角形钻入）固定；③一枚加压螺纹钉固定；④自行设计的外固定支架低角度倒三角形固定；⑤外固定支架按大角度固定。

Methods 34 bimaxillary protrusion adolescents were selected and 18 soft tissue of facial profile controls were compaired before and after orthodontic treatment with paired t-test to evaluate the changes in cranio-facial area.

结果 18项软组织指标中5项角度指标的改变在男性组与女性组的改变均有统计学意义， 13项线距测量指标中的上唇厚度、下唇厚度、鼻凸度均增，而鼻底厚度在男性组与女性组改变不同。

The convexity of facial profile decreases after orthodontic treatment for bimaxillary protrusion's adolescents with four premolars extracted, but there are differents in upper lip and lower lip in male and female.

结果 18项软组织指标中5项角度指标的改变在男性组与女性组的改变均有统计学意义， 13项线距测量指标中的上唇厚度、下唇厚度、鼻凸度均增大，而鼻底厚度在男性组与女性组改变不同。

Methods: 12 fresh frozen adult leg-foot specimens were mounted in a coordinated system, a Steinmann pin was perforated across the calcaneus, cuboidcum, talus, and naviculare as markers. The displacements of the marked points in the coordinated system were recorded. Through matrix translation and Euler equation, the rotational angle of the calcaneus, cuboideum, talus, naviculare were calculated, which represented the motion of the calcaneocuboid, talonavicular and ankle joint in different condition respectively, while statistical analysis were also taken between different conditions.
