CLAVICULAR, AND
ACROMIOCLAVICULAR
INJURIES
Carl J Basamania, MD, FACSINTRODUCTION•Few animals other than primates, birds, humans and,
surprisingly, marsupials have a functional clavicle.- Injuries to the clavicle and its articulations are very
common. - High energy injuries have been seen in increasing fre-
quency as more people participate in higher risk
sports such as mountain biking and rollerblading. - Since man is an upper extremity dependent animal,
these injuries can lead to significant disabilities and
limitations.
STERNOCLAVICULAR JOINT- The sternoclavicular joint is the only true articulation
between the upper extremity and the rest of the axial
skeleton. - Although the sternoclavicular joint has the least
amount of osseous stability of any major joint, it is
seldom injured in comparison to other joints.
