跟骨

ABSTRACT Objective To discuss the open reduction of calcaneus with titanium plate for calcaneal fracture.

目的 研究和评估切开复位治疗跟骨骨折及跟骨钛板在跟骨骨折治疗中的作用。

Methods 24 cases with calcaneal fracture received the treatment of open reduction of calcaneus and internal fixation with titanium plates.

目的 研究和评估切开复位治疗跟骨骨折及跟骨钛板在跟骨骨折治疗中的作用。方法对24例跟骨骨折患者行切开复位跟骨钛板内固定。

Preiss angle (P .0l ), for the stick pestle can complement the strength for correcting the broadenth of the cross radius of the calcaneus, and the plaster splints are strong enough to fix the ankle firmly at the metatarsus posture.

第二部分为生物力学的实验研究，采用电测法与三维光弹性实验，研究跟骨在中立位及不同角度的跖屈位时应力分布的规律，分析跟骨在不同体位时应力和位移情况，探讨跟骨骨折的发病规律及合理的治疗方法。

Principal axes method, was presented to figure out the rotational directions of talus and calcaneus and the angles between them.

采用最大类间方差法与交互式数学形态学方法相结合的手段从活体后足CT序列图像中分割出距骨和跟骨，以移动立方体法重建距下关节复合体的表面并以动画方式显示距骨和跟骨的结构信息，提出力矩主轴法计算距骨和跟骨相对于参考系的旋转方向及它们之间的夹角。

Tongue-type fractures of the calcaneus lead to variable amounts of displacement of the posterior tuberosity. This displacement may threaten the posterior soft tissue envelope.

跟骨舌型骨折可导致跟骨结节移位，移位的骨折块有可能损伤跟骨后侧的软组织皮瓣。

Bone trabecula just under the calcaneocuboid articular surface was compact and redundant, with the thickness about 5 mm. Conclusions: Screws can be implanted into the calcaneocuboid articular surface where is filled with compacted trabecula.

结果：跟骨骰骨关节面的横径为(22.67±2.14)mm；其内倾角为(60.4±7.1)°；紧邻跟骨骰骨关节面关节面下的压力骨小梁是致密的，厚度大约为5 mm，向后方和下方的骨小梁逐渐变得稀少、疏松。

The strew length of prefixed point was 41.84 mm, the screw angle with panes lateralis was 69.41°, the screw angle with inferior verticular plane of panes lateralis was 22.67°; the length of postfixed point was 42.28 mm, the angle with panes lateralis was 68.45°, the angle with inferior verticular plane of panes lateralis was 20.79°. Of the 60 nails drilled, two were drilled out of the post facies articularis of calcaneous, the accuracy rate was 97.67%.

其前点螺钉平均长度为41.84 mm，与跟骨外侧面平均呈69.41°、与跟骨外侧面的底垂面平均呈22.67°；后点螺钉平均长度为42.28 mm，与跟骨外侧面平均呈68.45°、与跟骨外侧面的底垂面平均呈20.79°；30足60枚钢针有2枚钻出跟骨后关节面，钻人安全率为97.67%。

Results:30 cases were shown calcaneal fracture in X-ray but it is difficult to show the details;MSCT axial image,combined with MPR,SSD post-processing technology can display the calcaneal fractures wholly,stereoscopically and accurately,especially the tiny fracture in the deep.

本文对36例44侧跟骨骨折患者的X线、MSCT横轴位扫描及SSD、MPR重建图像进行回顾性分析，评价各种图像对诊断跟骨骨折的价值。1材料与方法于2004年10月~2005年10月共收集36例跟骨骨折患者，男32例，女4例，年龄19~52岁，平均年龄38岁。

Methods The resection of a talocalcaneal coalition or triple arthrodesis was selected according to calcaneal eversion angle and the rate of a talocalcaneal coalition and the posterior surface area of the talocalcaneal joint.16 feet in 12 patients including 8 males and 4 females were operated upon and reviewed at a mean time of 18 months.

根据术前跟距轴位CT扫描所测量的跟距联合与跟距后关节二者横向切面之比率及跟骨外翻角度来决定采取跟距骨桥局部切除或三关节融合术。

Methods Fortythree cases of Itraarticular Fracture of the Calcaneus(46 feet) were treated with limited internal fixation with small incision and artificial bone implantation from June 2003 to June 2007.There were 34 male(37 feet) and 9 female(9 feet). Small incision was used extracalcaneus,collapsed facies articularis posterior calcanei after reduction,air containing space of Calcaneus were fiiled with hydroxyapatite ceramic artificial bone.

2003年6月—2007年6月作者采用微创小切口有限内固定联合人工骨植入的方法对43例46足跟骨关节内骨折进行治疗，其中男34例37足，女9例9足，术中运用跟骨外侧横行小切口，塌陷的跟骨后关节面复位后选用羟基磷灰石人工骨材料填充跟骨内空腔然后克氏针及螺钉固定。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
