The axis of the glenoid cavity proj-
ects 9° dorsally from the axis of the
scapula. It is thus in retroversion
with respect to the scapula.
The acromion is an anthropometric
point. Its lateral edge can be used
for measuring the shoulder-to-
shoulder width and the length of
the upper limb.
The scapula is connected by mus-
cles to the posterior aspect of the
thorax. Its position and associated
muscles influence the posture of
the head, cervical vertebrae and
shoulders. Contrarily, the position
of the scapula is significantly influ-
enced by muscular imbalance of the
upper and lower scapular fixators
and the serratus anterior.
