Clavicle fractures

Clavicle fractures are most common in children and young adults, typically occurring in persons younger than 25 years. Its superficial location, its thin midshaft, and the forces transmitted across it make the clavicle a common site for injury. The most common mechanism of injury is a forceful fall with the arm at the side, which commonly occurs during contact sports. Diagnosis can often be made by the history and physical examination, although appropriate radiography should be used to confirm the diagnosis and guide treatment options. Most clavicle fractures occur in the midshaft and can be treated nonoperatively. A prominent callus is common in children, and parents may require reassurance. If a child has no history of trauma, then malignancy, rickets, and physical abuse should be considered. Surgery is an option in fractures that have high potential for nonunion (e.g., displaced or communited fractures, fractures with more than 15 to 20 mm clavicle shortening). Distal fractures are classified based on the relationship to the coracoclavicular ligaments, which determines the likelihood of displacement. Most distal fractures can also be treated nonoperatively; however, certain factors must be considered in children.
