Tuberculosis infection of sternum is extremely rare. The most common cause of sternal osteomyelitis is infection of a median sternotomy incision, employed for most cardiac operation. If a wound infection of this regeon becomes apparent, the wound should be opened wide to allow adequate drainage. Frequent irrigation and debridement are necessary to avoid extension of the infection into the bone. We have experienced a 16 years old female who has been operated upon due to ASD, was infected with tuberculosis in sternum. Our team have treated her for tuberculous osteomyelitis on sternum with curettage and drainage.
