摘要：

背景：距骨作为踝关节重要组成部分之一，其形态直接影响着踝关节的稳定性和发病率。
目的：建立距骨数字化计算机三维模型，测量相关解剖数据，为踝部的手术设计提供解剖学参数。
方法：正常成人志愿者60例，男30例，女30例，进行 CT 扫描，扫描层厚1.25 mm，扫描间距1.25 mm，重建层厚0.625 mm，重建间距0.625 mm，Fov30×30 mm，矩阵512×512 dpi，球管电压150 kV，电流260 mA，将扫描原始数据以DICOM格式导入PC计算机，利用三维重建软件(比利时产Materrialise Mimics 13.01测试版)行后处理并测量。并按性别分组进行统计分析。
结果与结论：重建的距骨数字化虚拟可视模型能够从多平面进行观察及测量，距骨长、距骨宽、距骨高，滑车前宽、滑车后宽、滑车高、滑车长，内踝面长，外踝面长的测量值男性大于女性。测量获取的距骨解剖学数据对距骨疾患、手术器械的设计、个性化治疗方案的制定等均有重要参考意义。

Abstract:

BACKGROUND: Talus serves as an important part of the ankle joint, and its form directly affects the stability and morbidity of the ankle joint.
OBJECTIVE: To establish digital three-dimensional computer model of the talus, and then to measure the relevant anatomical data to provide anatomical parameters for operative design of the ankle joint.
METHODS: Sixty normal adult volunteers containing 30 males and 30 females were treated with CT scan. Scan slice thickness was 1.25 mm, scanning pitch was 1.25 mm, reconstruction slice thickness was 0.625 mm, reconstruction spacing was 0.625 mm, Fov 30×30 mm, matrix was 512×512 dpi, tube voltage was 150 kV and current was 260 mA. The original scan data were introduced into PC computer with the form of DICOM. Three-dimensional reconstruction software (Materrialise Mimics 13.01 test version produced in Belgium) was used for post-processing and measurement. Statistical analysis was preformed according to gender.
RESULTS AND CONCLUSION: The digital and virtual reconstruction model of talus could be observed and measured from multi-plane. Measurements of the length of the talus, width of the talus, height of the talus, the anterior width of the trochlea of talus, the posterior width of the trochlea of talus, the height of trochlea of talus, the length of trochlea of talus, the length of medial malleolar facet and the length of lateral malleolar facet in the male were larger than those in the female. Anatomical data from measurement have an important impact on talus diseases, the design of surgical instruments and the formulation of individualized treatment programs.
