Infectious<unk>  is the infection of closed synovial sheaths in the flexor tendons of the fingers. It is usually caused by trauma, but bacteria can spread from other sites of the body. Although<unk>  usually affects the flexor tendon of the fingers, the disease can also affect the extensor tendons occasionally. The clinical presentation is therefore as acute infection following trauma. The infection can be mono- or polymicrobial and can vary depending on the nature of the trauma. The most common pathogenic agent is Staphylococcus aureus introduced from the skin. Other bacteria linked to infectious<unk>  include Pasteurella multocida (associated with animal bites), Eikenella spp. (associated with IV drug use), and Mycobacterium marinum (associated with wounds exposed to fresh or salt water). Additionally, sexually active patients are at risk for hematogenous spread due to Neisseria gonorrhoeae (see infectious arthritis). Common noninfectious<unk>  are: stenosing<unk> , intersection syndrome, extensor pollicis longus (EPL)<unk> , de Quervain's and fourth compartment<unk> .
