Anatomy
Small hook-like bulge protruding laterally from top of axillary edge of scapula, over-hanging the gleno-humeral joint anteriorly, as the acromium does posteriorly.
Clinical
Its muscle and ligament attachments include the coracoclavicular ligament and (as with the acromium) they stabilize the shoulder joint, given the socket shallowness necessary to afford such a big range of movement.
Vignette
From the Greek for raven-like, ie like its beak. Can be felt just down from lateral end of clavicle, a point called the surgeon’s lighthouse; given major arteries and nerves pass medial to this, surgical entry is lateral.
