Avascular Necrosis (Avn) Of The Hip
What is Avascular Necrosis (AVN) of the Hip?
Avascular Necrosis (AVN) of the Hip occurs when blood supply to the femoral head is disrupted, leading to bone death and eventual collapse.
- Loss of blood supply to the femoral head
- Progressive joint degeneration
Overview of the Condition
AVN can result in severe pain and disability and often affects younger adults.
Symptoms
- Deep groin pain that may radiate to the knee
- Stiffness and limited range of motion
- Progressive difficulty with weight-bearing activities
Causes
Common causes include steroid use, excessive alcohol intake, trauma, and certain systemic diseases.
Diagnosis
Diagnosis is confirmed with MRI and X-rays, which reveal changes in the femoral head.
Treatment Options
- Conservative management with reduced weight-bearing and medications
- Core decompression or bone grafting in early stages
- Total hip replacement in advanced stages
Conservative Management
Early treatment may include medications, reduced activity, and physical therapy to delay progression.
Rehabilitation Exercises
- Low-impact exercises to maintain joint mobility
- Strengthening exercises for the lower extremity
- Gait training with assistive devices if needed
Surgical Options
Surgical treatment ranges from core decompression to total hip arthroplasty depending on the stage of AVN.
Anatomy Overview
The femoral head is particularly vulnerable to loss of blood supply, leading to avascular necrosis.
Affected Areas
- Femoral head
- Hip joint
