Impact of scapula anatomical landmark positioning on scapular orientation using CT-based 3-dimensional models: an intraobserver repeatability and interobserver reproducibility study

This study demonstrates that manual positioning of the 3 scapula anatomical landmarks recommended by the International Society of Biomechanics can be performed in a reliable manner across measures and observers on surface bone models obtained from CT scan images. However, a clear and standardized definition of these landmarks is needed to ensure consistency across measurements.
