Avascular Necrosis of the Hip or Femur

Hip or Femur Avascular Necrosis (AVN) 

Avascular Necrosis (AVN) is a frequent cause of concern for patients. When they are told they may have AVN, they are often surprised and confused by the conflicting information they receive. This may lead them on a search for alternative strategies such as Regenerative Medicine. AVN arises when the blood supply to a region of bone becomes compromised, leading to bone cell death or necrosis.

What Is Avascular Necrosis?

Avascular necrosis occurs most frequently from trauma. The hip is the most frequently encountered joint with AVN. A frustrating concern for patients is when no known cause or risk factor is readily identified. This leads to the term of idiopathic or unknown cause of the diagnosis. Other frequent causes or risk factors include excessive corticosteroids (cortisone), excessive alcohol use, Rheumatologic diseases, radiation and chemotherapy, and sickle cell disease.

Steps of Destruction….

The hip can develop AVN on both sides or may even be seen in one hip and a knee. Unusual presentations do develop, this is an important reason to seek the consultation of an expert such as Dr. Dennis Lox, who has treated AVN, and is familiar with treatment options including Regenerative Medicine. A frequent recommendation for hip AVN may be a hip replacement. This is why early diagnosis and consultation with an experienced physician in the treatment of hip and other forms of avascular necrosis is paramount. The key issue is the region of dead or necrotic bone may collapse, leading to a rapid destruction of the hip joint. Once the hip joint is destroyed options are limited. This is again why prompt diagnosis is important.

Avascular Necrosis Treatment Options

Athletes with hip AVN are often told they may need a hip replacement surgery. This is terrifying not just to a patient, but to the athlete, as this often means that it is an end to their sports career. This has led many to explore alternative treatment options such as Regenerative Medicine. The ability to help the body heal itself without surgery is a cornerstone of Regenerative Medicine. Tissue Engineering and Stem cell research are key aspects of Regenerative Medicine. This is very appealing to athletes. Not only can  Regenerative Medicine save their sports career, it may help them lead more productive lives, play sports longer, and alter the progressive nature of degenerative arthritis.
All things most active people, as well as athletes desire.
