Cauchon AM, Tetreault P, Bascans C, et al. - Researchers assumed that adding 3-dimensional morphologic parameters resulting from biplanar radiographs (3DXR parameters) to the MRI parameters would improve this association. This study examined 52 individuals with rotator cuff tears with an EOS Imaging radiographic assessment, MRI study, and clinical evaluation of the shoulder, as well as the Constant score.  The findings suggested that the combination of MRI and 3DXR parameters of the shoulder in a linear regression model improves the association with the Constant score (shoulder function) at diagnosis for patients with rotator cuff tears.
