The clavicle is an s-shaped bone that serves as the only direct bony attachment of the arm to the trunk. The medial portion of the clavicle has a tubular cross section, resists axial loading, and protects the brachial plexus and other structures in the costoclavicular space. The flat lateral portion provides sites for muscle and ligament attachment. The transition between the two sections is relatively weak and at risk of fracture when the bone is overstressed. Clavicle fractures account for approximately 1 in 20 (5%) of all fractures and 44% of all injuries to the shoulder girdle. The most common mechanisms of injury for a clavicle fracture is falling on the tip of the shoulder or a direct blow to the front of the shoulder
