What is osteomyelitis primarily caused by?

Osteomyelitis is primarily caused by a bacterial infection, with Staphylococcus aureus being one of the most common pathogens involved. This condition refers to an inflammation of the bone or bone marrow that usually arises from a bacterial infection that can enter the bone through various means, such as a fracture, surgical procedure, or from an infection elsewhere in the body that spreads through the bloodstream.

Bacterial pathogens can effectively penetrate the bone, leading to inflammation and necrosis of the bone tissue. The body's immune response to the infection causes further damage and can lead to chronic osteomyelitis if not treated appropriately. While other infections or conditions might have some impact on bone health, osteomyelitis is distinctly linked to bacterial infections and is not generally associated with viral infections, autoimmune disorders, or metabolic conditions.
