Acromio

When these movements of the arm are arrested in the shoulder-joint by the contact of the bony surfaces, and by the tension of the fibers of the capsule, together with that of the muscles acting as accessory ligaments, the arm can be carried considerably farther by the movements of the scapula, involving, of course, motion at the acromio - and sternoclavicular joints. ❋ Unknown (1918)

The lateral end forms with the acromion the acromio-clavicular joint, which, however, is not always readily identified. ❋ Alexander Miles (1893)

In rare cases the fracture passes into the acromio-clavicular joint, and is associated with dislocation of the clavicle. ❋ Alexander Miles (1893)

In this way, however, the knee-joint may be dislocated, one bone being driven past the other -- for example, by a kick from a horse; or the acromio-clavicular joint by a blow on the shoulder. ❋ Alexander Miles (1893)

He was scrambling for a loose ball when he landed on the side and back of his shoulder, pulling the acromio clavicular ligament, which is in the front of the shoulder and holds the shoulder blade to the collarbone. ❋ Unknown (2010)

Grade I separation occurs when the ligaments holding the joint together (the acromio-clavicular capsule and ligaments) are bruised, but still mostly intact. ❋ Unknown (2009)
