Abstract:

BACKGROUND: Biomechanics research of ankle joint increasingly becomes a hot spot. Research method in previous studies is traditional biomechanical research that has developed to finite element mechanical analysis
OBJECTIVE: To establish a three-dimensional finite element digital model of ankle joint and to discuss the stress distribution of various components in the ankle joint.
METHODS: An adult woman was selected to treat with spiral CT scanning on ankle. The obtained images were processed by Mimics and Geomagic for the establishment of three-dimensional finite element digital model.
RESULTS AND CONCLUSION: The three-dimensional finite element digital model was established, including distal tibiofibular shaft and talus. With realistic appearance and excellent geometry-comparability, the rotatable model of ankle is available to be observed from different perspectives, to be collected three-dimensional data and is valid for biomechanical study.
