Femoral neck fracture calcar femoral fracture fixation , internal CEPS

股骨颈骨折，股骨距，骨折固定术，内

The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.

3动力髋螺钉虽然在固定强度上优于其它各组，但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用；自行设计的外固定支架为一种简单、有效、实用、经济的固定方法，有一定的推广价值；穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。

(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。

The fracture toughness testing technique for the central cracked circular disk specimen is given to investigate the fracture behavior of brittle material polymethyl methacrylate under pure mode Ⅰ, pure mode Ⅱ and mixed-mode loadings. The experimental results show that the load distribution angle is always greater than 8° for all different loading conditions.

给出一个中心裂纹圆盘断裂试验的较完整的试验技术，并用此试验技术在岛津材料试验机上对有机玻璃(polymethyl methacrylate， PMMA)这种典型的脆性材料成功地进行纯Ⅰ型、纯Ⅱ型和复合型加载条件下的断裂试验。

In view of practical problem during Sulige gas field development, this paper complete follow study content. Study material balance theory of two district compound gas reservoir. Carry out stress sensitivity experiment on matrix rock and labor created fracture core from Sulige gas field with America Core Company high pressure high temperature flow experimental instrument to study stress sensitivity change rule of different permeability matrix rock and created fracture core at the condition of time and again switch on and off well and different drawdown pressure. Carry out depletion experiment on matrix rock of different permeability serial combination with different kinds of allocation, using double core clamper serial connected experimental apparatus, to study gas well production performance of bi-zonal compound low permeability reservoir during low pressure production stage. At the basis of experimental study, establish single well simulation model to analyze development index infection caused by stress sensibility and production performance infection rule caused by inner formation and outer formation of bi-zonal compound gas reservoir permeability variation while considering stress sensitivity.

针对苏里格低渗气田开发中存在的实际问题，完成以下研究内容；研究了两区复合气藏物质平衡原理；利用美国岩芯公司高温高压流动实验仪，对取自苏里格气田基质岩芯和人工造缝岩芯进行应力敏感实验，研究不同渗透率基质岩芯和造缝岩芯在多次开关井和不同生产压差条件下的应力敏感变化规律；采用双岩芯夹持器串联实验装置，对不同渗透率串联组合的基质岩芯进行各种配产条件下的衰竭实验，研究两区复合的低渗储层气井在低压生产阶段的生产动态特征；在实验研究的基础上，建立单井模拟模型分析储层应力敏感性和非均质性对开发指标的影响，研究考虑应力敏感时两区复合气藏储层中内区和外区渗透率变化对开发动态的影响规律。

目的 探讨由轻创伤而引起的桡骨远端骨折病人的骨质密度与骨折发生的相互关系。

Functions of wrist joint in cases with wrist joint instability were inferior to that with simple colles fracture after fracture union.

骨折愈合后，合并腕关节不稳定的功能明显差于单纯Colles骨折患者。

Methods The radiographs of the second metacarpal in64 patients with Colles' fracture were measured for assessment of bone density atfracture,and six weeks,six months and one year after fracture.

于首次就诊及伤后6周、6个月、1年测定64名Colles骨折患者的第2掌骨骨密度，并于伤后1年进行功能评定。

Various reasons may cause the missed diagnosis of fracture in the compages of thorax.Once fracture is suspected clinically and negative plain radiography encountered,CT scanning is recommended.

摄片质量、阅片水平、机器设备等均可导致胸背部骨折的漏诊，对临床高度疑有骨折的病例应进一步行CT检查。
