An osteosynthesis plate analytical model

Abstract

Osteosynthesis plates are used to fix broken bones to help the healing process consolidation. It consists in fixing a plate on a long-bone external surface with screws, sharing forces, and moments between bone and plate. In this paper, a straight osteosynthesis plate is analyzed using an analytical bi-material model, based on mechanics of solids, to estimate the mechanical stress distributions at plate medial cross sections. The analytical model results show good performance in comparison with the commercial finite-element software used as reference.
