Chapter 12 Infection

, ,

Bone and joint infections, while less common than other types of infections, present unique challenges and significant clinical problems. This chapter delves into the complexities of these infections, categorized broadly as septic arthritis (joint infection), osteomyelitis (bone infection), and infections related to surgical implants.

Septic Arthritis: This occurs when bacteria, fungi, or viruses invade the synovium, causing joint inflammation. The knee is most commonly affected. Symptoms include swelling, warmth, tenderness, and limited range of motion. Causes range from bloodborne bacteria to direct inoculation or spread from nearby infections. Risk factors include age, impaired immunity, and intravenous drug use. Staphylococcus aureus… Read more
