Orthopaedic infections affect bones, joints, and surrounding tissues, often caused by bacteria such as Staphylococcus aureus. Common infections include osteomyelitis, a bone infection, and septic arthritis, which affects the joints. These infections can occur after surgery, trauma, or the spread of bacteria from other body areas. Symptoms typically include pain, swelling, redness, and fever. Early diagnosis through blood tests, imaging, and tissue cultures is critical for effective treatment, which may involve antibiotics and, in some cases, surgical intervention to drain abscesses or remove infected tissue. Preventing orthopaedic infections requires proper hygiene, wound care, and appropriate use of prophylactic antibiotics during surgery.
