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。

This method for treatment of nonunion of scaphoid fractures, with it effectiveness, simpleness,and minor side injuries,was worthy of wide use.

该手术方法疗效好、副损伤小、操作简单、易于推广；为治疗腕舟骨骨不连的有效方法。

The X-ray photo, tectology, and the superfine structure of cells all display: The healing of the horizontal-shaped fracture is faster than that of the skewed fracture in the early and middle stages of fracture (2, 4, 6 weeks after operation).

而斜形骨折因骨折断端不在同一平面上，所受应力和位移相差较大，近端受力大，位移小，远端受力小，位移大，要使之破坏只要较小的加载力骨折近端即可首先出现断裂，继之因应力集中而波及整条骨折线，使骨骼再次骨折。

Using dual energy X-ray bone density instrument XR-36 model to detect the bone mineral density of the left femur of the rats. Using the strain test system, we examined the biomechanics index according the tension and three-spot bending test; we also examined the bone calcium of the lumbar vertebra through plasma emission spectroscopy . We examined the serum calcium and magnesium by using the nomal biomechanics method,and examined the serum acid phosphatase and osteocalcin by using the Elisa method.
