Femur Bone

The femur bones of two male human specimens (Femur 1: aged 44; Femur 2: aged 69) were prepared using digital imaging and CT scans for modeling in FE software. They were first imaged with CMM optical 2015 by GOM Co., Germany, then modeled as shells using cloud points in STEP format within CATIA V5/R21. Solid models were created next. For the central cavity and inner layer, a precise CT scan method was employed, creating sections with 10 mm distances that were visualized in Adobe Photoshop CC. These sections were then imported into SolidWorks 2013 to model the cavity using the lofted cut module. The trabecular or marrow bones weren't included in the finite element model, and the proximal and distal regions of the femur were excluded for studying the critical buckling load of the bone shaft.
