Clinical ROM was measured in abduction, external rotation at resting abduction, extension, and flexion at a minimum of 1 year postoperatively. All clinical measurements were obtained before generation of PPS ROM values. Using postoperative CT scans, the achieved implant component positions were quantified and then replicated in PPS on the preoperative CT scans. The preoperative predicted ROM was then recorded, both with and without osteophyte removal. Bland-Altman plots were generated within each motion comparing the differences between clinically measured motion and software-predicted motion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The variation in clinically measured ROM in abduction, external rotation at resting abduction, extension, and flexion were 118 \u00b1 27 (65\u00b0 to 180\u00b0), 33 \u00b1 16 (10\u00b0 to 75\u00b0), 56 \u00b1 8 (50\u00b0 to 65\u00b0), and 137 \u00b1 25 (80\u00b0 to 160\u00b0), respectively. Clinically measured motion differed greatly from PPS-predicted ROM, with mean differences of 33 \u00b1 29 (\u221232 to 93) for abduction, 44 \u00b1 25 (\u221238 to 57) for external rotation, 44 \u00b1 25 (\u221235 to 65) for extension, and 54 \u00b1 50 (\u221251 to 147) for flexion with no significant correlations between clinically measured and PPS-predicted ROM (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; 0.05).

<jats:p>The passive glenohumeral impingement-free ROM generated from PPS incompletely predicts clinically measured active humerothoracic ROM, possibly because of the unmeasured factors of soft-tissue tension, muscular strength, humeral torsion, resting scapular posture, and, most importantly, scapulothoracic motion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
