Table 2.

Topographical areas projected on the lines between the references points, expressed in % of the respective line lengths (median, 95% central range)

Topographical area	Distance in %	Distance in %	Distance in %
Topographical area	AB line^a	AC line^b	BC line^c
Subscapular fossa	54.0 (46.5–94.9)	37.1 (33.0–79.2)	8.7 (− 1.6 to 64.7)
Supraspinous fossa	44.3 (37.8–62.4)	29.0 (24.8–38.0)	− 2.1 (− 6.1 to 1.7)
Infraspinous fossa	57.7 (49.7–87.8)	40.2 (33.3–53.9)	6.7 (− 4.1 to 20.4)
Peri-glenoid	40.6 (23.5–52.4)	37.9 (15.8–46.7)	28.7 (− 10.2 to 37.7)

^aAB line—distance between the anterolateral acromion (0%) and the medial border spina (100%)

^bAC line—distance between the anterolateral acromion (0%) and the inferior scapular angle (100%)

^cBC line—distance between the medial border spina (0%) and the inferior scapular angle (100%)
