Shoulder joint angles in supine and upright imaging of the preoperative reverse total shoulder arthroplasty patient
Patient-specific variation in joint angles between supine and upright poses demonstrates gross changes in both magnitude and direction that exceed common thresholds in implant selection and placement. Thus, preoperative planning using supine CT may inaccurately pose bones, with consequent effects on the surgical plan, the resultant shoulder biomechanics, and clinical outcomes. Preoperative planning software should consider the influence of supine posture when orienting bones for surgical planning.
