objective to elucidate the choice of three defferent ways as well as the clinical efficacy in the treatment of pilon fracture and different damages of skin and tissue.methods 29 cases were treated with calcaneum bone traction and small splinting,23 cases were treated with internal fixation,11 cases were treated with external fixation of ilizarov.results all cases were followed up for 8～31 months (15.3 months average).according to helfet criterion,the results were evaluated as the total excellent and good outcome accounted for 90.5％.conclusion the key point of treatment is rational selection of three defferent ways in the treatment of pilon fracture according to the typle of pilon fracture and different damages of skin and tissue.

目的 探讨pilon骨折的三种不同治疗方法临床适应证及其疗效评价。方法对2000年2月至2006年3月间治疗的63 例pilon骨折患者进行回顾性分析。其中开放性损伤15 例，闭合性损伤48 例。根据骨折类型与周围软组织损伤程度，分别采用三种不同治疗方法：跟骨牵引加小夹板固定组(29 例)均为闭合性骨折，内固定组(23 例)，外固定器组(11 例)。结果所有患者均获得随访，随访8～31个月(平均15.3个月)，骨愈合时间8～14周，平均10周。按helfet疗效评价标准，本组优良者57 例(90.5％)，其中ⅰ型骨折优良者26 例，ⅱ型骨折优良者15 例，ⅲ型骨折优良者16 例。

(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。

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。

Because of the enhancement in chromium absorptivity and fixation,the dosage of normal chrome powder can be reduced from 6%to 4%in conventional process,and can be reduced from 6%to 3%in two-stage chrome tanning process,and thus the chrome absorptivity and fixation can be enhanced further.

两步铬鞣时可将标准铬粉的用量由传统的6%减少到3%，这时铬的吸收率和固定率还会进一步提高。

Summary of Background Data. Pedicle or anterior screw fixation is commonly used with interbody deice fixation.

在48块胸腰椎椎体中，选用椭圆形或者四叶状的锯齿边缘的压力器，接触椎体的面积约为40％的终板面积，作轴向压迫。
