Chronic joint pain and stiffness may be symptoms of avascular necrosis (AVN), a rare condition that can occur in any joint but is most common in the hip. Duke orthopaedic surgeons are nationally recognized experts in the treatment of avascular necrosis, also known as osteonecrosis. When avascular necrosis is diagnosed and treated early, the right treatment can reduce your pain, stop progressive bone damage, and restore your function. Our surgical expertise in avascular necrosis treatment, including free vascularized fibular grafting and hip preservation surgery, may minimize your need for joint replacement surgery in the future.
