Avascular Necrosis (AVN)
What is Avascular Necrosis (AVN)?
Avascular Necrosis (AVN), also known as Osteonecrosis, is a condition where the blood supply to the hip bone is reduced or completely cut off. Without enough blood, the bone tissue starts to die, leading to pain and joint damage. If left untreated, AVN can cause hip joint collapse, making movement difficult.
Causes of AVN
The exact cause of AVN is not always known, but some common risk factors include:
- Trauma or Injury - A hip fracture or dislocation can damage blood vessels.
- Excessive Alcohol Consumption - Alcohol affects blood circulation and weakens bones.
- Steroid Use - Long-term use of steroids (such as prednisone) can increase the risk.
- Medical Conditions - Diseases like sickle cell anemia, lupus, and blood clotting disorders can contribute to AVN.
- Smoking - Reduces blood flow to the bones, increasing the risk of AVN.
Symptoms of AVN
- Mild pain in the hip that worsens over time.
- Pain while walking, standing, or moving the hip joint.
- Stiffness and restricted hip movement.
- In later stages, difficulty in bearing weight on the affected leg.
Diagnosis & Treatment
Early diagnosis is important to prevent joint damage. MRI, X-rays, and CT scans help detect AVN. Treatment options include:
- Medications: Pain relievers and bone-strengthening drugs.
- Physiotherapy: Helps improve mobility and reduce stiffness.
- Core Decompression Surgery : Reduces pressure inside the bone to improve blood flow.
- Hip Replacement Surgery:Required in advanced cases for pain relief and better movement.
Final Remark
If you experience persistent hip pain, don’t ignore it. Early treatment can prevent complications and improve quality of life. Consult an orthopedic specialist for proper diagnosis and care.
