Hip Avascular Necrosis (AVN)

Avascular Necrosis (AVN) of the hip, also known as osteonecrosis, is a serious orthopedic condition where the blood supply to the femoral head (hip ball) becomes disrupted or reduced. Without adequate blood flow, the bone tissue begins to die, which can lead to the collapse of the femoral head, joint destruction, and ultimately hip arthritis.

  1. Hip Avascular Necrosis (AVN) Avascular Necrosis (AVN) of the hip, also known as osteonecrosis, is a serious orthopedic condition where the blood supply to the femoral head (hip ball) becomes disrupted or reduced. Without adequate blood flow, the bone tissue begins to die, which can lead to the collapse of the femoral head, joint destruction, and ultimately hip arthritis. Timely diagnosis and treatment are essential to preserve joint function and avoid total hip replacement in advanced cases.

  2. Causes of AVN AVN can occur due to various medical conditions or lifestyle factors. The most common causes include: Trauma or fracture near the hip joint Prolonged use of corticosteroids Excessive alcohol consumption Sickle cell disease Autoimmune or blood disorders Radiation therapy Decompression sickness Unknown causes (Idiopathic AVN) Who is at Risk? AVN can affect both men and women, typically between the ages of 20 and 50. Risk factors include: Chronic steroid therapy Heavy alcohol use Hip dislocations or fractures Blood clotting disorders Lupus or other autoimmune diseases Smoking Symptoms Early stages of AVN may not show noticeable symptoms. As the disease progresses, patients may experience: Deep pain in the groin, thigh, or buttock Pain during walking or climbing stairs Limping or restricted movement Increased discomfort after physical activity Loss of hip motion in severe cases

  3. Diagnosis A thorough clinical examination is supported by imaging studies: X-ray: Detects structural changes in bone MRI: Most sensitive test for early AVN CT scan: Provides 3D imaging of bone condition Bone scan: Assesses bone activity and blood flow Treatment Options Treatment depends on the stage of AVN, severity of symptoms, and patient's overall health. Non-Surgical (Early Stage) Activity modification and use of walking aids Pain management with NSAIDs Bisphosphonates to slow bone damage Physiotherapy to maintain joint mobility Core decompression: A minimally invasive surgery to reduce pressure and promote blood flow Surgical (Advanced Stage) Bone grafting: Replacing dead bone with healthy tissue Osteotomy: Realigning the joint to redistribute weight Total Hip Replacement (THR): Replacing the damaged joint with an artificial implant for pain relief and mobility Stem cell therapy: Used in select early cases to regenerate bone Prognosis When diagnosed early, AVN can be effectively managed and even reversed in some cases. In advanced stages, surgical options like hip replacement offer excellent outcomes, with most patients regaining near-normal function.

  4. Conclusion Hip Avascular Necrosis is a progressive condition that can severely impact mobility and quality of life if left untreated. However, early diagnosis and appropriate intervention can prevent joint destruction and preserve function. If you're experiencing persistent hip pain or are at risk for AVN, consult an orthopedic specialist without delay.
