Avascular Necrosis
Osteonecrosis
Call for an AppointmentChronic 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.
Duke orthopaedic clinics are located throughout the Triangle. Find one near you.
Avascular Necrosis Treatment Experts
Years of Experience
Our orthopaedic specialists see people from around the world with AVN. Our years of experience and high surgical volumes ensure you have the best possible outcome.
A Dedicated Team
Your surgeon works closely with a team of physician assistants, nurses, anesthesiologists, physical therapists, and occupational therapists who are dedicated to your care. We provide you with the most accurate information and best possible care in a compassionate and timely manner.
Alternative to Hip Replacement Surgery
Avascular necrosis of the hip frequently occurs in people between the ages of 20 to 35, ages at which hip replacement may not be the best option. In these cases, we offer an approach that we pioneered -- free vascularized fibular graft -- which allows younger patients to delay or possibly eliminate the need for hip replacement in the future. We are a training center for doctors who want to learn how to do this procedure.
High-Volume Hip Replacement Hospital
When a hip replacement is needed, we offer every approach: from the back (posterior), the front (anterior), and the side (lateral). Our orthopaedic surgeons perform more than 1,000 hip replacements every year.
Experts in Microsurgical Techniques
Our orthopaedic surgeons use microscopes and precision instruments during bone grafting procedures. These techniques knit together tiny blood vessels and restore blood flow to areas damaged by AVN.
Ongoing AVN Research
Our researchers study osteonecrosis in hopes or gaining a better understanding of the disease, including how to prevent and treat it before it progresses.
Coordinated Care with Your Local Orthopaedic Surgeon
If you travel to Duke for your avascular necrosis surgery, we share our notes and imaging results with your surgeon. You will return to Duke one year after your surgery for a follow-up visit. You may see your local orthopaedic surgeon for other follow-up visits.
