title: Posterior sternoclavicular dislocations: two case reports.
abstract: Posterior sternoclavicular joint dislocations are thought to be exceedingly uncommon. Two recent cases are discussed in terms of diagnosis, management, and potential risk to the patient. One dislocation was successfully reduced with lidocaine infiltrated and the second, seen 72 hours postinjury, required closed reduction under general anesthesia. Soon after injury these patients have a hollow at the sternoclavicular junction. Sternal oblique X-rays and tomograms are helpful in diagnosis. This entity may be promptly recognized and treated in the emergency department with gratifying results.
