What is AVN?

Avascular Necrosis (Aavn-avascular-necrosisVN) is a medical condition in which the blood supply to a region of bone becomes impaired. This in term disrupts the nutrition to the bone, and cellular death occurs and the bone dies. This loss of blood supply is referred to medically as avascular or ischemia. When the bone dies it is called necrosis. The bone may collapse and degenerate leading to an accelerated secondary arthritis. This is what destroys most joints leading often to joint replacement surgery.

The hip, shoulder, knee, and ankle are frequently affected but many different bones can develop avascular necrosis (AVN). It is also sometimes referred to as osteonecrosis, ischemic necrosis, aseptic necrosis and bone infarction. The prognosis for avascular necrosis was previously guarded, however now in the Regenerative Medicine era, the use of Stem Cell Therapy and Platelet Rich Plasma (PRP) have changed the way patients are viewing their condition.

Stem cell therapy may allow the region of avascular necrosis to heal. This occurs by the reparative qualities of stem cells and the nature of how the body can heal itself with assistance of modern medicine. Even athletes are continuing to play their sport with avascular necrosis (AVN). It is extremely important to halt the progression of secondary joint arthritis to allow a functional life without hip, shoulder, or knee replacement as well as continue to play spavn-avacular-necrosis-hiports.

Stem Cell therapy for avascular necrosis or osteonecrosis, needs to be evaluated by an experienced Sports and Regenerative specialist. Dr. Dennis Lox has treated many varieties of avascular necrosis from trauma in athletes, to medical conditions. Dr. Lox has kept athletes in multiple sports stay in competition.
