Comparison of the results of sinus track culture and sequestrum culture in chronic osteomyelitis.

A prospective observational study was conducted at J. N. Medical College, Aligarh Muslim University, to compare the bacterial flora obtained from sequestrum culture and sinus track culture and to evaluate their antibiotic sensitivity. A total of 62 patients with chronic osteomyelitis were enrolled (38 males and 24 females). Sinus track cultures were done taking all aseptic precautions and the results were compared. Thirty three patients out of 62 showed a discrepancy between the bacterial flora grown from sinus track and sequestrum cultures.
