Finite element (FE) modeling applied to orthopaedic biomechanics is increasing in popularity. An area of current interest is in the development of the time-dependent material models of bone tissue that can be applied to the study of natural bone formation or changes in bone density following joint replacement surgery. This thesis focuses on the development of such a model for the distal ulna, with implications for implant design.
This was completed in a series of three studies. First, an empirically derived density- elastic modulus relationship for the ulna was validated through a range of bending modes. Second, a strain-adaptive material model for the distal ulna was developed and optimized. Third, this material model was used to assess the influence of implant material on the extent of bone resorption using a commercially available prosthetic.
These studies represent the first application of a strain-adaptive material model to arthroplasty of the distal ulna
