M86: Osteomyelitis

M86.2: Subacute osteomyelitis

Subacute osteomyelitis is an inflammation of the bone and bone marrow, often caused by a bacterial infection, which develops over a period of time, usually weeks to months. Unlike an acute case, this less-severe form progresses slower and is sometimes less dramatic in its symptoms, which can lead to a delay in diagnosis. Symptoms may include localized bone pain and tenderness, fever and chills, and occasionally swelling over the affected bone. Various parts of the body can be affected, such as the long bones in the arms and legs or the vertebrae in the spine. The condition develops when bacteria or fungi invade a bone, often via the bloodstream or following injury or surgery. Without treatment, it can lead to serious complications such as bone destruction or abscess.
