What is Angular Orientation of Trabecular Bone in the Femoral Head and Its Relationship to Hip Joint Loads in Leaping Primates about?
## Abstract The elastic properties and mechanical behavior of trabecular bone are largely determined by its three‐dimensional (3D) fabric structure. Recent work demonstrating a correlation between the primary mechanical and material axes in trabecular bone specimens suggests that fabric orientation may be used to infer directional components of the material strength and, by extension, the hypothetical loading regime. Here we quantify the principal orientation of trabecular bone in the femoral head and relate these principal fabric directions to loading patterns during various locomotor behaviors. The proximal femora of a diverse sample of prosimians were scanned using a high‐resolution X‐ray computed tomography scanner with resolution of better than 50 μm. Spherical volumes of interest were defined within the femoral heads and the 3D fabric anisotropy was calculated using the mean intercept length and star volume distribution methods. In addition to differences in bone volume and anisotropy, significant differences were found in the spatial orientation of the principal trabecular axes depending on locomotor behavior.
