Avascular necrosis is a medical condition that affects bones. This condition will cause the bones to die. Necrosis or tissue death to the bones occurs when the blood supply to the bones is obstructed. The bones will then collapse.

The common areas where avascular necrosis can occur are the shoulders, knees, ankles and in the hip, though it can affect any bones in the body. If the necrosis involves the bones of a joint, often times this would lead to joint destruction. In a lot of case, pain and discomfort in the joints are experienced and becomes worse over time. The classical sites that are often involved in the necrosis are:

  • The femur head,
  • Neck of talus
  • Scaphoid waist

Avascular necrosis is also called osteonecrosis, bone infarction, aseptic necrosis, and ischemic bone necrosis.

There is no specific cause why this disorder occurs. However, there are risk factors that may contribute to its development. These are:

  • Chemotherapy
  • Alcohol abuse
  • Excessive use of steroids
  • Caisson disease or decompression sickness, a condition where the body is exposed to high pressure
  • Vascular compression
  • Hypertension
  • Vasculitis
  • Arterial embolism
  • Thrombosis
  • Radiation damage
  • Bisphosphonates
  • Sickle cell anemia
  • Gaucher’s disease, a metabolic disorder wherein fatty substance accumulate in the organs
  • Lupus

Early detection of the disease would prompt early treatment, delaying the need for joint replacement.

If you think you are suffering from Avascular Necrosis you should seek medical assistance. You may also be entitled to Social Security Disability Benefits. The SSA considered Avascular Necrosis as a medical condition that would make you eligible for SSDI and SSI. Social Security Administration (SSA) maintains a “Listing of Medical Impairments” (known as the blue book) that automatically qualify you for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI).
