How does the femoral cortex depend on bone shape? A methodology for the joint analysis of surface texture and shape

•We consider cohorts of surfaces with scalar data at each vertex: textured surfaces.•The joint analysis of shape and texture is of interest but also inherently ambiguous.•The ambiguity may be resolved using homologies to guide vertex correspondences.•This is an extention of Geometric Morphometric Image Analysis to textured surfaces.•The method reveals how cortical bone depends on shape in the human proximal femur.
