Clavicle and acromioclavicular joint injuries: a review of imaging, treatment, and complications

Abstract

Fractures of the clavicle account for 2.6-5% of all fractures. Clavicular fractures have traditionally been treated conservatively, however, there has recently been increased interest in surgical repair of displaced clavicular fractures, with resultant lower rates of nonunion and malunion. Treatment of acromioclavicular (AC) separation has traditionally been conservative, with surgery reserved for patients with chronic pain or significant dislocation and acute soft tissue injury. It is important for the radiologist to become familiar with the surgical techniques used to fixate these fractures as well as the post-operative appearance and potential complications.
