CT scans are now routinely obtained for patients undergoing
planned TSR at our institution. The CT scan protocol included
0.5-mm axial cuts with inclusion of the entire scapula in the
Digital Imaging and Communications in Medicine (DICOM)
format. CT scans from other institutions were included if they met
the specifications. The study initially enrolled 23 consecutive
patients. Four were excluded due to the poor quality of the CT
scans or CT scans that did not include the medial border of the
scapula. The remaining 19 patients with acceptable CT scans were
included prospectively in this study.
