The contribution of trabeculae and the failure initiation in the proximal femur: a finite element analysis.

ABSTRACT:

Background

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.

Methods

Bilateral hip CT scans from 10 healthy volunteers were included in this study. 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 techni
