HR-pQCT-based 3D statistical surface model of the right scaphoid demonstrating 3D shape and size variation pattern of osseous and articular surfaces. Columns display 1st and 2nd PC with 3D views revealing most relevant variation patterns: 1st PC with ± 2 SD models (top and bottom row) and mean model (middle row) mainly exhibited size variation, i.e. length. 2nd PC with ± 2 SD models (top and bottom row) and mean model (middle row) with predominately a 3D shape variation of the osseous and articular surfaces (osseous surface (purple) and cartilage surfaces (yellow: cartilage surface for capitate, red: for lunate, green: for trapezium and trapezoid, blue: for radius))
