Fig. 12From: A predictive model for the critical shoulder angle based on a three-dimensional analysis of scapular angular and linear morphometricsAssessment of the acromial orientation: a Axial plane angulation of the acromion (APAA): The mesh is positioned in the axial viewing plane and the angle between the longitudinal lateral acromial axis and the y axis is measured (angle labelled x); b Sagittal plane angulation of the acromion (SPAA): the mesh is positioned in the sagittal viewing plane and the angle between the longitudinal lateral acromial axis and the z axis is measured (angle labelled x); c Coronal plane angulation of the acromion (CPAA): the mesh is placed in the baseline position and the angle between the transverse lateral acromial axis and the x axis is measured (angle labelled x)Back to article page
