Septic Arthritis
One of the consequences of infections of native joints is the development of suppurative arthritis. It is estimated that between two and five people in every hundred thousand of the general public will develop septic arthritis, this increases to around 35 people per hundred thousand in rheumatoid arthritis sufferers and to as high as 68 people in people who suffer from joint prostheses. Some of the events that precede this trauma include intravenous drug use and std’s, HIV, and diabetes. Skin infections are also often a cause of suppurative septic arthritis.
Staphylococcus aureus, may causes acute septic bursitis in up to 77% of cases. This usually occurs at the olecranon and pre-patellar bursea. Bacterial arthritis is also a common problem that leads to septic arthritis.
Chronic arthritis of joints is often a consequence of being infected by fungi. Some of the fungi that can cause chronic arthritis include Sporothrix schenckii (elbow, knee, wrist,) and Coccidioides immitis (knee, especially in americans). Following a trauma of the knee or elbow Pseudallescheria boydii may cause septic arthritis in tropical areas.
