Clavicular tuberculosis following trivial trauma.

Tuberculosis of the clavicular bone is a very rare clinical entity, with limited cases reported in the United States. Furthermore, sparing of the sternoclavicular joint is exceedingly unusual. A literature review of the prevalence of clavicular tuberculosis identified fewer than 80 cases reported since the discovery of the tubercular bacillus, over a century ago. To our knowledge, there have been no cases reported over the last decade in the United States. A rare case of tuberculous osteomyelitis of the clavicle in an immunocompetent patient who presented with swelling of the upper chest is reported.
