Infections of the tendon sheath.
Trauma, sex (for some the same thing).
Any penetrating trauma can lead to infection. The nature of the trauma leads to consideration of microbiology. An animal bite is different than a knife. (:Unless the knife was cleaning a cats mouth, I suppose:) S. aureus and streptococci are most common; Candida, nontuberculous mycobacteria and Sporothrix schenckii, after injection from organic material (the rose thorn is a risk, but over rated, for Sporothrix; any woody material has Sporothrix, except Woody Harrelson).
Disseminated N. gonorrhoeae can present as a migratory tenosynovitis.
Depends on what caused the trauma. Acute is usually nafcillin / oxacillin OR cefazolin OR vancomycin PLUS/MINUS third generation cephalosporins OR quinolone. Usually treat with IV for 2 (streptococcal) to 3 (staphylococcal) weeks.
Do not treat with po.
Have a very low threshold for surgery, a little inflammation in a tendon sheath can lead to beaucoup problems with movement.
Treating without debridement is usually destined to failure, disability and a lawsuit.
