Methods: We retrospectiely analyzed twenty-four hips in twenty patients who underwent a Bernese periacetabular osteotomy, which was done with a proximal femoral algus-producing osteotomy in thirteen hips, for the treatment of acetabular dysplasia associated with proximal femoral structural abnormalities.

我们回顾性分析20位患者中的24例髋关节，他们都进行过Bernese periacetabular截骨术，对于髋臼发育不良合并股骨近段的结构异常分别在13例髋关节完成了股骨近段外翻截骨成型术。

RESULTS: SEM results showed that the fiber morphology of P(50/50) 6% nanofibers membrance was better and more uniform diameter distribution. Mechanic test indicated nanofibers membrance of P(50/50) had longer breaking elongation but smaller breaking stress than nanofibers membrance of P(75/25). Hydrophilicity of P(75/25) fibers was better. MTT results proved that 6% and 8% P(50/50) nanofibers could enhance the adhesion and proliferation of endothelial cells on the surface of materials, and the cells had the best spreading and attachment on the nanofibers.

结果：通过扫描电镜观察发现由质量分数为6%聚(50/50)制备的纤维膜具有更好的纤维形态，且直径分布均匀；拉伸力学测试显示由聚(50/50)制备的纤维膜比聚(75/25)具有更高的断裂伸长率，但断裂应力较低；细胞生物相容性实验表明猪髋动脉内皮细胞在质量分数为6%和8%聚(50/50)的纳米纤维膜上更能有效的黏附与增殖。

Methods:BMD of right calcaneus was measured in the male and female with hip fracture over60years.

测定60岁以上新入院髋部骨折患者的右跟骨骨密度值。

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。

The rate of excellent and good functional recovery of hip was 94.0%. Postoperative internal-fixation-related complications occurred in 31 cases, including hip varus in 14 cases who had posterior intertrochanteric fragments, delayed union of fracture in 12 cases who had fractured calcar and lesser trochanter and massive dissection of soft tissues, and cutting-out of lag screws in five cases, three of whom had to receive prosthetic replacement.

术后髋关节功能恢复良好率达94.0%。215例患者中31例出现内固定相关术后并发症，其中髋内翻14例，主要发生于股骨转子内后方存在明显骨折碎裂的患者；骨折延迟愈合12例，为骨折累及股骨距及小转子，术中做软组织广泛剥离、骨折复位固定的患者；内固定物股骨头颈内切割并螺钉穿入髋关节腔5例，其中3例再行人工关节置换，关节功能Harris评分为82分。

Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

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。
