The sternoclavicular joint: a review of anatomy, injury and management

Abstract

The sternoclavicular joint is the only true joint connecting the upper limb with the axial skeleton and is reliant on its capsular and ligamentous attachments for stability. Injuries to the sternoclavicular joint are uncommon and include sprains, dislocations, and fractures. Dislocations and medial clavicle fractures are often associated with high-energy trauma and can lead to life-threatening complications secondary to mediastinal injuries, particularly with posterior sternoclavicular joint dislocations. Given the rarity of these injuries, there are multiple case reports and retrospective studies detailing novel surgical techniques for managing injuries of the sternoclavicular joint and no single option has been implemented. We conducted a literature search on Medline, EMBASE and CINAHL to identify relevant articles focusing on sternoclavicular joint dislocation and subluxation, and medial clavicle fractures in adults. This review article aims to describe: the anatomy of the sternoclavicular joint; injuries including dislocation and medial clavicle fractures; and current investigation and management options including closed and open reduction techniques.
