Stage 4 AVN (avascular necrosis) in the hip is a serious condition that requires comprehensive treatment. Surgery is usually recommended to address the underlying cause of the condition, as well as to reduce pain and improve mobility. Depending on severity, the type of surgery may vary, but may include bone grafts, joint replacement, or core decompression. Physical therapy and medications may also be part of a comprehensive treatment plan.
Surgery
Bone grafts are used to replace damaged bone in the hip joint. The healthy bone is taken from another part of the body, such as the pelvis, and implanted into the hip joint. This helps to restore normal bone structure and can help alleviate symptoms of AVN.
Joint replacement is a surgical procedure in which the damaged hip joint is removed and replaced with a prosthetic joint. This procedure is recommended when the hip joint is severely damaged, as it will help to improve mobility and reduce pain.
Core decompression is a surgical procedure that is used to reduce pressure on the hip joint by removing a portion of the bone. This helps to reduce pain and improve blood flow to the joint, which can help to reduce the symptoms of AVN.
Physical Therapy
Physical therapy can be an important part of the treatment plan for Stage 4 AVN in the hip. Physical therapists can help to strengthen the muscles and ligaments around the hip joint, which can help to improve mobility and reduce pain. They can also provide advice on activities and exercises that can help to improve hip function and reduce pain.
Medications
Medications can also be used to treat Stage 4 AVN in the hip. Non-steroidal anti-inflammatory drugs (NSAIDs) can help to reduce inflammation and pain. Corticosteroids can also be used to reduce inflammation and pain. Other medications, such as opiates, can be used to manage pain. It is important to talk to your doctor about the risks and benefits of any medications before starting them.
