Fig. 13From: A predictive model for the critical shoulder angle based on a three-dimensional analysis of scapular angular and linear morphometricsAssessment of the scapular spinal orientation: a Axial plane scapular spine angulation (APSSA): The mesh is positioned in the axial viewing plane and the angle between the scapular spinal axis and the y axis is measured b) Sagittal plane scapular spine angulation (SPSSA): the mesh is positioned in the sagittal viewing plane and the angle between the scapular spinal axis and the z axis is measured (labelled x). c Coronal plane scapular spine angulation (CPSSA): the mesh is placed in the baseline position and the angle between the scapular spinal axis and the x axis is measured (labelled x)Back to article page
