Avascular Necrosis (AVN), also called Osteonecrosis, is a serious condition where the blood supply to the head of the femur (thigh bone) is reduced or completely cut off. Without proper blood flow, the bone tissue starts to die, leading to joint pain, stiffness, and, in advanced stages, collapse of the hip joint.
At KS Ortho Care, we specialize in early diagnosis and advanced treatment options for AVN, helping patients regain mobility and prevent further hip damage.
AVN occurs when there is a disruption in the blood supply to the femoral head. Common causes include:
Injury or Trauma – Hip dislocations or fractures
Long-term Steroid Use – High-dose corticosteroid medications
Excessive Alcohol Consumption – Weakens the blood vessels and bone structure
Medical Conditions – Sickle cell disease, lupus, and blood clotting disorders
Idiopathic AVN – In some cases, the cause remains unknown
AVN often develops gradually and may worsen if left untreated. Watch out for:
Persistent pain in the hip, groin, or thigh
Stiffness and reduced range of motion
Pain while walking, climbing stairs, or sitting
Limping due to discomfort
Difficulty standing for long periods
AVN is classified into four stages based on severity:
Stage 1: Early AVN, minimal symptoms, visible only on MRI
Stage 2: Bone structure starts weakening, mild pain begins
Stage 3: Femoral head begins to collapse, severe pain develops
Stage 4: Advanced joint damage, leading to hip arthritis
Our specialists use advanced imaging techniques to diagnose AVN accurately:
X-rays to detect structural changes
MRI scans to identify early-stage AVN
CT scans for detailed 3D bone analysis
At KS Ortho Care, treatment depends on the stage of AVN and the patient’s overall health:
1. Non-Surgical Management (Early Stages)
Medications to manage pain and improve blood flow
Activity modification to reduce stress on the hip
Physiotherapy to maintain flexibility and muscle strength
Bisphosphonates to slow bone damage
2. Surgical Treatments (Moderate to Advanced Stages)
Core Decompression: Removing part of the dead bone to improve blood supply
Bone Grafting: Restoring bone strength using healthy tissue
Osteotomy: Reshaping the bone to reduce joint stress
Total Hip Replacement (THR): Recommended in severe AVN cases for long-term pain relief and mobility restoration
Expert Orthopedic Surgeons specializing in hip disorders
Early detection using advanced diagnostic tools
Minimally invasive surgeries for faster recovery
Personalized treatment plans designed to suit each patient’s condition
Comprehensive rehabilitation support for long-term recovery
