Septic arthritis of the hand and wrist.

Abstract

Septic arthritis of the hand and wrist is relatively uncommon. The most common cause is penetrating trauma such as a human or animal bite. The most common causative organism is Staphylococcus aureus. Septic arthritis caused by Streptococcal species. Haemophilus influenzae, Pseudomonas aeruginosa, Serratia species, Neisseria gonorrhoeae, Pasteurella multocida, Eikenella corrodens, and Mycobacterium marinum also may occur in specific clinical settings. The best clinical results occur following an accurate diagnosis, prompt surgical drainage, and debridement in concert with appropriate antibiotics and early postoperative range of motion. A delay in diagnosis or treatment is associated with an unsatisfactory outcome.
