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.
