Causes And Risk Factors Linked To Avascular Necrosis

Trauma To The Joints And Bones

Trauma to the joints and bones can interrupt blood circulation and result in bone death. For example, injuries such as fractures and dislocations may damage blood vessels close to the affected joints, which could compromise blood flow. For this reason, patients who have experienced a fall or other injury should have a prompt assessment with their clinician. To assess trauma to the joints and bones, doctors can perform x-rays, CT scans, and other imaging studies, and patients may need to be referred to an orthopedic surgeon for specialist care. 

To reduce the risk of avascular necrosis following trauma, doctors may recommend braces and other assistive devices that reduce the weight placed on the affected joint. Treatments to stimulate the growth of new bone may be advised, and surgical options such as bone grafts, joint replacements, core decompressions, and osteotomy might be appropriate.
