Can a bone infection be cured?

Most cases of osteomyelitis are treatable. Chronic infections of the bone, however, may take longer to treat and heal, especially if they require surgery. Treatment should be aggressive because an amputation can become necessary sometimes. The outlook for this condition is good if the infection is treated early.

How does bone infection lead to necrosis?

What causes the death of bone cells in a joint?

Osteonecrosis, also known as avascular necrosis (AVN), aseptic necrosis or ischemic bone necrosis, is a disease resulting in the death of bone cells. If the process involves the bones near a joint, it often leads to collapse of the joint surface and subsequent arthritis due to an irregular joint surface. The exact cause is unknown.

When does a bone collapse due to lack of blood?

Osteonecrosis (ON) is a condition where an insufficient supply of blood to the bone results in bone tissue death. With a continued shortage of blood and an ineffective repair process, the bone eventually collapses after tiny breaks (or microfractures) occur. Osteonecrosis is also known as avascular necrosis, aseptic necrosis and ischemic necrosis.

What happens if you have an infection in your bone?

An infection in your bone can impede blood circulation within the bone, leading to bone death. Areas where bone has died need to be surgically removed for antibiotics to be effective. Septic arthritis. Sometimes, infection within bones can spread into a nearby joint.
