Abstract The objective of the paper is to address the methodology developed to model bone and joints 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 have been established between mechanical properties and quantitative data derived from measurements on medical images. Subsequently, geometric and numerical models of bones with individualised geometrical and mechanical properties have been developed from the same source of image data. The advantages of this modelling technique are its ability to study the `patient' specificity. 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 suggest improvement or development of new design.
