Avascular Necrosis (AVN)

What is Avascular Necrosis (AVN)?

Avascular Necrosis (AVN) occurs when the blood supply to the femoral head (hip bone) is disrupted.

This leads to:

• Weakening of the bone
• Gradual collapse of the joint
• Severe pain and restricted movement

Common Causes:

• Steroid use (especially post-COVID treatment)
• Alcohol use
• Trauma or injury
• Conditions like sickle cell disease

Why AVN Cases Increased After COVID-19

• High-dose steroid use during treatment
• Faster onset of symptoms
• Younger patients being affected

👉 Early diagnosis is now more important than ever.

Why Early Treatment Matters

• The hip joint can collapse completely
• Pain becomes severe and constant
• Walking and daily activities become difficult
• Surgery (hip replacement) may become unavoidable

👉 Early intervention can save your natural hip joint.

When is Surgery Required?

For advanced stages of AVN, Total Hip Replacement (THR) remains the most reliable solution.

Benefits of Modern Hip Replacement:

• Long-lasting implants (25–30 years)
• Restoration of mobility
• Ability to sit, walk, and perform daily activities comfortably

Research-Backed Treatment You Can Trust

• Over 20 years of clinical research
• High success rates compared to conventional treatments
• Thousands of patients treated successfully

👉 Focus: Preserve the joint whenever possible, operate only when necessary.
