Physical Therapy Nest

A provider may diagnose AVN through:

• Medical history review (injury, medication use, or risk factors like alcohol or corticosteroid use).

• Physical exam to assess hip mobility, pain location, and walking ability.

• Imaging tests:

  • X-rays may look normal in the early stages but show changes later.

  • MRI is the most sensitive tool for detecting early AVN before bone collapse.

  • CT scans may be used to evaluate advanced cases.

Treatment depends on the stage of AVN and the extent of bone damage. Physical therapy can help manage symptoms, improve function, and support recovery. Therapy may include:

• Strengthening exercises for the hip, glutes, and core to improve stability

• Range of motion exercises to maintain joint mobility

• Assistive devices (like canes or crutches) to reduce weight-bearing stress

• Pain management with heat, ice, or electrical stimulation

• Education on activity modification to protect the hip
  In early stages, medications or procedures to improve blood flow may be recommended. In advanced cases, surgical options such as core decompression, bone grafting, or hip replacement may be necessary, with physical therapy playing a key role in post-surgical rehab.

Avascular necrosis symptoms often develop gradually and may include:

• Dull, aching pain in the groin, thigh, or buttock

• Stiffness and reduced hip mobility

• Pain that worsens with weight-bearing (standing, walking, climbing stairs)

• Limping or difficulty walking

• In advanced stages, severe pain and loss of function due to bone collapse

To lower the risk of developing AVN or slow its progression:

• Limit alcohol consumption

• Use corticosteroid medications only when medically necessary

• Maintain healthy cholesterol levels to promote good circulation

• Protect the hips by avoiding high-risk trauma or repetitive injury

• Seek early medical care for unexplained hip pain

• Stay active with low-impact exercise to maintain joint health
