Risk factors
By Mayo Clinic staffOsteomyelitis occurs more often in men than in women. People of any age can develop osteomyelitis, though the acute form tends to be more common in children, and people older than 50 are more likely to have the spinal form of the infection.
You also have an increased risk of osteomyelitis if you have:
- An increased risk of infections. Certain situations allow germs more opportunities to access your body, putting you at an increased risk of infection, which can lead to osteomyelitis. Examples include people who illegally inject drugs, people on dialysis, people who use urinary catheters and people who have had tubes placed in their bodies to give doctors easier access to major veins (central lines).
- Poor circulation. People with poor circulation include those with diabetes, peripheral arterial disease and sickle cell disease. When the arteries are damaged or blocked, your body has difficulty distributing the infection-fighting cells needed to keep a small infection from growing larger.
- A recent injury. A broken bone that breaks the skin or a deep puncture wound exposes your body to germs that can cause infection and increase your risk of osteomyelitis. Carefully follow your doctor's instructions on taking antibiotics and taking precautions to prevent infection.
- Orthopedic surgery. Surgery to repair broken bones or replace worn joints puts you at risk of infection. Follow your surgeon's instructions to help avoid infection after your surgery.
