Two types of geometric models of the ipsilateral proximal femur were constructed using Mimics: an intact model (cortical-cancellous composite model) and a cancellous-excised model. In total, 20 geometric models were generated (two per volunteer). Material properties were assigned based on Hounsfield Unit (HU) values. A lateral fall condition was simulated, and the element deletion techniJournal of orthopaedic surgery and research1022https://www.ebi.ac.uk/biostudies/studies/S-EPMC12639791biostudies-literatureThe contribution of trabeculae and the failure initiation in the proximal femur: a finite element analysis.PMC12639791Jia PYang YFang ZTang XfalseThe contribution of trabeculae and the failure initiation in the proximal femur: a finite element analysis.<h4>Background</h4>This study employed finite element analysis to simulate the process of hip fractures, aiming to: (1) quantify the contribution of trabeculae to proximal femoral strength, (2) compare fracture patterns before and after the removal of trabecular bone, and (3) identify the fracture initiation site.<h4>Methods</h4>Bilateral hip CT scans from 10 healthy volunteers were included in this study.
