Parameter measurement method in the cortical change region. A The line around at the base of the lesser tuberosity was chosen as the plane to measure the cortical thickness of the surgical neck region. Three points were selected adjacent to the bicipital groove (anterolateral), middle of the cortical change region and posterolateral point. B The valid height of the cortical change region was measured. Valid height represents the minimum height of the cortical change region with same color (cortical thickness) in this 3D bone map
