Sternoclavicular Injuries

SC joint dislocations: anterior (more common, often stable after reduction) vs posterior (rare but life‑threatening due to mediastinal compression). Posterior dislocation red flags: dyspnea, dysphagia, venous congestion, neurologic symptoms—urgent reduction under anesthesia with cardiothoracic standby. Imaging: CT with contrast preferred; plain X‑rays often inadequate. Management: sling and rehab for sprain/anterior dislocation; posterior often requires closed/open reduction and stabilization (figure‑of‑8 graft). Beware physeal injuries in adolescents (medial clavicular physis).
