OSTHEOSYNTHESIS OF THE CALCANEUS WITH A C-NAIL

Abstract

: This article deals with the strength analysis of an intramedullary nail (internal fixator), used in traumatology/orthopaedic for a broken heel bone (calcaneus). The application focuses on the unique mini-invasive C-NAIL produced by the company Medin a.s. (Nové město na Moravě, Czech Republic). The focus is on types of calcaneal fractures and the possibilities of treating them, on the analysis of calcaneus load and the creation of a CAD-FEM model of the calcaneus from CT images (design – the engineeering point of view). Consequently, an analysis is carried out of the peripheral conditions including loading. The calculations were done on solid („healthy“) bones and bones cut into indidivual bone fragments (imitating broken bones), using the finite element method in the Ansys Workbench application.
