Displacement until acromion contact at all tested flexion angles for normal and pathological scapulae. In 60° and 90° flexion, the normal and the “B1” model had acromion contact. However, the “B1” model showed significantly more translation until acromion contact occurred. In 120° flexion, the “B1” model showed significantly more posterior translation until acromion contact occurred and eventually dislocated while the “normal” model had acromion contact and remained stable. Values in mean, bars show SD
