Septic Arthritis of the Shoulder.

In brief A wrestler developed septic arthritis in his glenohumeral joint. His case is unusual because septic arthritis most commonly affects weight-bearing joints and is usually seen in the very young, the very old, and people who are immunocompromised. Other risk factors include concurrent infection, endocarditis, invasive procedures, and intra-articular corticosteroid injection. Disease onset is usually insidious. Nonspecific findings include restricted motion, mild pain, and joint effusions; systemic signs of toxicity are often mild or absent. Diagnosis is confirmed with joint aspiration and analysis and culture of synovial fluids; definitive treatment often involves arthroscopic debridement followed by 2 to 6 weeks of antibiotics.
