Septic Arthritis
Considered as the most dangerous form of acute arthritis, septic arthritis is caused by a bacterial infection in the joint cavity. Usually there is a primary site of infection from where bacteria spread. The site of infection is often along adjacent bone or soft tissue. Bacterial spread is usually through the bloodstream going to the joints. It is estimated that in the general population of 100,000 people, about 2 to 10 of them suffer from septic arthritis.
