AVN Q&A

What is avascular necrosis (AVN)?

Avascular necrosis is a progressive condition where the blood supply to a bone becomes interrupted, leading to the gradual breakdown and death of bone tissue. Over time, this damage can cause the bone to collapse, resulting in arthritis or loss of joint function.

While AVN can develop in any bone, it most commonly affects weight-bearing joints such as the hip, knee, shoulder, or ankle. Early diagnosis is essential, as prompt treatment can slow progression and help preserve the affected joint.

What causes avascular necrosis?

AVN can result from traumatic injury or reduced blood circulation to the bone. Common causes and risk factors include:

Fractures or dislocations that damage nearby blood vessels
Long-term corticosteroid use
Excessive alcohol consumption
Blood disorders, such as sickle cell anemia
Radiation therapy or chemotherapy
Autoimmune or metabolic diseases

In some cases, AVN develops without a clear cause (idiopathic AVN). Regardless of its origin, untreated AVN can cause progressive joint pain, stiffness, and eventual bone collapse.

What are the symptoms of AVN?

Symptoms vary depending on the affected joint, but typically include:

Deep, aching pain in the hip, knee, shoulder, or groin
Pain that worsens with movement or weight-bearing activity
Joint stiffness or limited range of motion
A limp or difficulty walking
Gradual loss of mobility over time

Pain may begin mildly and intensify as the condition advances, making early evaluation critical.

How is avascular necrosis diagnosed and treated?

Dr. Mohan performs a detailed physical examination and may order X-rays, MRI scans, or CT scans to assess the extent of bone damage and blood flow. Early-stage AVN can often be managed with nonsurgical treatments designed to reduce pain and slow bone deterioration.

Treatment options at Pain Specialists of Frisco may include:

Anti-inflammatory or pain-relief medications
Bisphosphonate therapy to prevent bone loss
Corticosteroid or regenerative injections for inflammation control
Platelet-rich plasma (PRP) or Regenexx® stem cell therapy to promote bone healing
Physical therapy to improve joint strength and mobility

Dr. Mohan prioritizes conservative, minimally invasive care whenever possible, helping patients maintain mobility and prevent the need for joint replacement surgery.
