Bone and joints modelling with individualized geometric and mechanical properties derived from medical image: application to the evaluation of osteoarticular pathology

摘要

The paper addresses a methodology of bone and joints modelling with individualised geometric and material properties from medical image data. An atlas of mechanical properties of human bone has been investigated demonstrating individual differences. From these data, predictive relationships has been established between mechanical properties and quantitative data derived from measurements on medical images. Subsequently, numerical models of bones with individualised geometrical and mechanical properties have been developed from the same source of images data. This should be of importance for quantifying bone and joint deformities and performing individualised preoperative planning surgery or orthopaedic treatment. In the same way, the efficiency of orthopaedic treatment with customised orthese or mechanical behaviour of implant in bone could be evaluated. Results would be of importance for improvement or development of new design.
