Avascular Necrosis of the Femoral Head: Treatment Options and Recovery

Avascular necrosis of the femoral head

Hello, Doctor: I was diagnosed with avascular necrosis of the femoral head in early February this year at the Penghu Naval Hospital, affecting both legs, with a smaller area of necrosis in the right leg.
I will undergo a decompression surgery at Kaohsiung Medical University on March 11.
What other methods can assist in my recovery? (Currently, my left leg often experiences sharp pain, and I am unable to lift it or exert force, but I can still walk normally, although with some difficulty.
The right leg feels like a muscle strain.) Additionally, my left leg has already collapsed, and the orthopedic doctor in Penghu suggested that I should undergo a hip replacement as soon as possible, preferably a partial hip replacement.
Since I am young, my recovery ability is better, and delaying might require a total hip replacement.
However, the doctor at Kaohsiung Medical University advised against replacement at my age, suggesting I wait until I can no longer walk before considering a total hip replacement.
Given my current situation, should I proceed with the replacement? What is the approximate cost for a self-funded hip replacement?

Dr. Hong Ximing reply Orthopedics

Bilateral femoral head necrosis is best supported by X-ray evidence.
Before the acetabulum is damaged, a hemiarthroplasty can be performed, but ultimately a total hip arthroplasty will be necessary.
Decompression surgery is a procedure performed prior to joint replacement.
Currently, the cost of self-funded artificial hip joints varies depending on the material used.
Please visit a hospital as soon as possible to discuss in detail with an orthopedic specialist.
Wishing you a speedy recovery.

More Info

Avascular necrosis (AVN) of the femoral head is a condition that occurs when there is a loss of blood supply to the femoral head, leading to bone death and potential collapse of the bone structure. This condition can be quite debilitating and often requires a multifaceted approach to treatment and recovery.

In your case, it’s important to understand that the treatment options for AVN can vary significantly based on the stage of the disease, the extent of bone damage, and the patient's overall health and activity level. Since you mentioned that both of your hips are affected, with the left side being more severely impacted, your treatment plan will likely need to be tailored accordingly.

Treatment Options
1. Conservative Management: Initially, many patients are treated conservatively, especially if the condition is diagnosed early. This may include:
- Activity Modification: Reducing weight-bearing activities to minimize stress on the affected hip.

- Physical Therapy: Engaging in physical therapy can help maintain joint function and strengthen the surrounding muscles, which may alleviate some pain and improve mobility.

- Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation.

2. Surgical Options: If conservative management does not provide relief or if the condition progresses, surgical options may be considered:
- Core Decompression: This procedure involves removing a portion of the inner bone to reduce pressure and promote blood flow to the area.

- Bone Grafting: In some cases, bone grafting may be performed alongside core decompression to help restore the structural integrity of the femoral head.

- Osteotomy: This involves cutting and repositioning the bone to redistribute weight away from the damaged area.

- Hip Replacement: If the femoral head has collapsed or if there is significant joint damage, a hip replacement may be necessary. Given your age and the current state of your left hip, a partial hip replacement (hemiarthroplasty) may be considered, but it is crucial to weigh the benefits against the risks and potential need for future surgeries.

Recovery and Rehabilitation
Recovery from AVN and its treatments can be a lengthy process. Post-surgery, rehabilitation will be essential to regain strength and mobility. This may include:
- Physical Therapy: A structured rehabilitation program focusing on range of motion, strength training, and functional exercises.

- Gradual Return to Activities: Depending on your recovery progress, you may gradually return to normal activities, but it’s important to listen to your body and avoid overexertion.

Decision on Hip Replacement
Regarding your question about whether to proceed with a hip replacement now or wait, this is a decision that should be made in consultation with your orthopedic surgeon. Factors to consider include:
- Current Symptoms: If your left hip is causing significant pain and functional limitations, it may be worth considering surgery sooner rather than later.

- Long-term Outcomes: Early intervention may lead to better long-term outcomes, especially if your condition is likely to worsen over time.

- Surgeon’s Recommendations: Different surgeons may have varying opinions based on their experiences and the specifics of your case.

Cost Considerations
As for the cost of hip replacement surgery, this can vary widely based on location, the specific hospital, and whether you have insurance coverage. In the United States, the cost of a hip replacement can range from $30,000 to $50,000 or more, depending on various factors. It’s advisable to check with your healthcare provider and insurance company for specific details regarding coverage and out-of-pocket expenses.

In conclusion, managing AVN of the femoral head requires a comprehensive approach that includes both conservative and surgical options, depending on the severity of the condition. Engaging in open discussions with your healthcare team will be crucial in determining the best course of action for your specific situation.
