Osteomyelitis is infection in the bone. Osteomyelitis can occur in infants, children, and adults. Different types of bacteria typically affect the different age groups. In children, osteomyelitis most commonly occurs at the ends of the long bones of the arms and legs, affecting the hips, knees, shoulders, and wrists. In adults, it is more common in the bones of the spine (vertebrae), feet, or in the pelvis.
What causes osteomyelitis?
There are several different ways to develop the bone infection of osteomyelitis. The first is for bacteria to travel through the bloodstream (bacteremia) and spread to the bone, causing an infection. This most often occurs when the patient has an infection elsewhere in the body, such as pneumonia,
an abscessed tooth, or a urinary tract infection that spreads through the blood to the bone.
An open wound over a bone can lead to osteomyelitis. This happens most commonly with underlying peripheral vascular disease, peripheral neuropathy, or diabetes. With an open fracture (compound fracture), the bone that punctures through the skin is exposed to bacteria. This increases the risk of osteomyelitis.
A recent surgery or injection around a bone can also expose the bone to bacteria and lead to osteomyelitis.
While the patient's history and physical examination are the building blocks of making a medical diagnosis, the ability to peer inside the body can be a powerful tool. Ultrasound is an imaging technique that provides that a"...
