Clavicle fractures are a very common injury in the pediatric and adult populations. Lately, the literature has seen a growing number of reviews, meta-analysis, and randomized control trials that provide a more thorough input on the treatment of clavicle fractures. This chapter first reviews the clavicle anatomy, epidemiology, and risk factors of clavicle fractures. The chapter then describes the mechanism of injury and clinical presentation of those fractures before presenting different classifications of clavicle fractures, their treatment, and complications. Finally, future trends in the treatment of clavicle fractures will briefly be discussed.
