Sternoclavicular Dislocation MDGuidelines

Description: The sternoclavicular joint is a saddle-like joint that links the arm to the torso and allows free movement of the collarbone (clavicle) in almost all planes. Sternoclavicular joint dislocation is the displacement of the clavicle from its normal position relative to the breast bone (sternum). Anterior sternoclavicular (SC) joint dislocation occurs when the medial end of the clavicle is pushed forward toward the outside of the chest from its normal position (anterior dislocation). Posterior (retrosternal dislocation) occurs when the clavicle is pushed backward into the chest.
