Fig. 6From: A predictive model for the critical shoulder angle based on a three-dimensional analysis of scapular angular and linear morphometrics3D mesh images demonstrating: a undersurface acromion viewing plane. b posterolateral acromion viewing plane. The scapular plane is marked with a visible grid. The ‘world origin point’ has been placed in the centre of the glenoid (red dot). The location of the ‘acromiospinal point’ in this view has been marked with a spherical ‘pivot’. c use of a gridline to re-orientate the image. The mesh has been re-orientated to the axial viewing plane by ensuring that the x plane grid appears as a lineBack to article page
