Mycobacteria, both tuberculous and nontuberculous, are recognized as a cause of chronic bone and joint infection. However, the diagnosis of mycobacterial infection is easily missed because of the absence of systemic involvement. Moreover, specific microbiologic techniques are required to detect mycobacteria in clinical specimens. Infections due to uncommon pathogens such as mycobacteria are more likely to occur in the immunocompromised host. A case of septic arthritis of the ankle and osteomyelitis of the foot due to both tuberculous and nontuberculous mycobacteria in an immunocompetent host is reported here.
Osteomyelitis has always been a difficult disease to classify, diagnose, and treat. Its etiology and course are not fully understood. A review of the traditional aspects of osteomyelitis is presented along with the discussion of a more recent classification system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
