Producing a three-dimensional biomechanical, anatomical and educationally interactive model of the equine carpus.

摘要

The equine carpal joint frequently sustains injury such as fractures, cartilage lesions, ligament tears and inflammation, partially due to the repetitive impact of more than 170% of a horse's body weight on a single limb during a racing gallop. Frequent injury warrants in-depth biomechanical and anatomical study of the carpus. In this thesis, the static kinematics and bone surfaces of the equine carpal joint were collected using a novel and accurate white-light measuring technique. Soft tissue surface models were created from 3D MRI scan segmentation and registered to the white-light surface data. Kinematic data for the joint in six discrete joint flexion positions are reported. A 3D anatomy teaching module for veterinarians was created, including soft tissue data, user interaction and correlation to MRI data. The module was given to a first-year veterinary anatomy class and evaluated via a survey, which indicated the computer model of the equine carpus was effective in giving a good spatial understanding of the joint.
