Arm positions with increased risk of subscapularis external impingement at the subcoracoid arch
This cadaveric study demonstrated increased subcoracoid arch contact when shoulders were at 20° and 60° FF with IR and at 60° ABD with both ER and IR. These findings suggest potential external subscapularis impingement in these positions, although not all comparisons were statistically significant. Level of evidence: Cadaveric biomechanical study.
