Strain Analysis in Cementless Hip Femoral Prosthesis using the Finite Element Method – Influence of the Variability of the Angular Positioning of the Implant[*]
Article in several languages: português | English
Abstract
Objective The present study aims to evaluate the influence of different positioning of the hip femoral prosthesis on the stress and strain over this implant.
Methods A femoral prosthesis (Taper - Víncula, Rio Claro, SP, Brazil) was submitted to a stress and strain analysis using the finite element method (FEM) according to the International Organization for Standardization (ISO) 7206-6 Implants for surgery – Partial and total hip joint prostheses – Part 6: Endurance properties testing and performance requirements of neck region of stemmed femoral components standard. The analysis proposed a branch of the physical test with a +/− 5° angle variation on the standard proposed for α and β variables.
Results The isolated +/− 5° variation on the α angle, as well as the association of +/− 5° variation on the α and β angles, presented significant statistical differences compared with the control strain (p = 0.027 and 0.021, respectively). Variation on angle β alone did not result in a significant change in the strain of the prosthesis (p = 0.128). The stem positioning with greatest implant strain was α = 5° and β = 14° (p = 0.032).
Conclusion A variation on the positioning of the prosthetic femoral stem by +/− 5° in the coronal plane and/or the association of a +/− 5° angle in coronal and sagittal planes significantly influenced implant strain.
