A total of 292 dry, intact scapulas (152 right, 140 left) has been used for this table. AB, AC, AD, the comparison among three types in the acromion breadth, the acromion length, the distance of the scapular spine. A, B, C, the comparison among three types in the thickness of the anteroinferior point of the acromion, the corner of the superior point of the acromion and the tip of the acromion. A, α, the comparison among three types in the angle of the acromial angle and the angle of inclination of the acromion.
