Abstract

Ovine models are widely used in orthopaedics and trauma research. We present the development and validation of an FE model of an ovine tibia for use in the testing of tibia fracture fixation plates. The FE model was generated from CT data of a cadaveric tibia and validated by mechanical testing of the bone. An offset 3-pt bend test was conducted with strain gauges placed on the anterior and posterior surfaces of the diaphysis. The loads applied during testing were applied to the model after digitising their location and orientation with a 3D digitiser. A comparison of the surface strains was conducted. Initial results show a good correlation between the mechanical test and the FE model with calculated strain values within 2% of the measured strains. Further improvements are expected with the incorporation of bone density-specific material properties in the model.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
