Cadaveric validation study comparing glenoid morphometric measurements obtained from 3D CT reconstructions against direct physical measurements of 12 excised scapulae. Asks whether 3D CT can accurately capture glenoid version, surface dimensions, surface area, and vault volume for preoperative total shoulder arthroplasty planning.
When planning total shoulder arthroplasty in a patient with significant glenoid bone loss or deformity, 3D CT reconstruction gives you version accuracy within ~2° and surface dimensions within ~2.5 mm — specific enough to guide component sizing and corrective reaming strategy where standard axial CT may mislead you due to gantry angle artifact.
