Comparison of tensile strain (εt​), compressive strain (εc​), and maximum principal stress (σt) and volume of bone with strains exceeding 90th percentile (VNHR, %) between 3D (blue lines) and slice-based (red lines) finite element (FE) models across three conditions: no lesion (BS), lateral parasagittal groove lesion (LGL), and bicondylar palmar osteochondral disease lesion (BCL) in the equine third metacarpal bone (MC3). Each graph represents values sampled across consecutive 3 mm-wide mediolateral regions of interest (ROIs). Vertical dashed lines indicating anatomical landmarks of lateral condyle (LC), lateral parasagittal groove (LPSG), sagittal ridge (SR), medial parasagittal groove (MPSG), and medial condyle (MC) for each joint. Both tensile and compressive strains are plotted as positive magnitudes.
