title: Posterior sternoclavicular joint dislocation.
abstract: Posterior sternoclavicular (SC) joint dislocations are rare but can have serious complications, such as hemorrhage or tracheal rupture or compression. Described here is the case of a 21-year-old college football player who fell on his right shoulder and, on the basis of a physical exam and plain radiographs, was first diagnosed as having an apophyseal injury of the SC joint. Increased shoulder and throat pain led to further evaluation; a CT scan revealed a posterior SC joint dislocation. Knowing the signs and symptoms that characterize these dislocations, the role of CT in diagnosis, and the techniques of emergency reduction can prevent or minimize serious complications.
