MODELLING AND STRENGTH SIMULATIONS IN A HIP JOINT EQUIPPED WITH AN OVERLAY PROSTHESIS AS A DIAGNOSTIC PROCEDURE BEFORE THE HIP RESURFACING OPERATION
Journal Title: Tribologia - Year 2013, Vol 248, Issue 2
Abstract
The study presents the modelling of overlay elements used in hip resurfacing and their virtual application into the patient’s reconstructed bone structures that had been imaged in Computed Tomography (CT). Strength calculations were conducted and in the implanted hip distributions of stresses and displacements were determined for accepted, three-dimensional configuration of loads in FEMAP/Nastran v. 8.3. The results allow the analysis of constructional elements of the endoprosthesis, the contact zone of overlay of head and cup, as well as their influence on the pelvic and femoral bones of the operated hip.
