AVN of the hip is most commonly caused by use of corticosteroids, such as too high doses for short periods of time, or lower doses for prolonged periods of time. Excessive alcohol intake can also restrict the flow of blood to the bones, increasing one’s risk of AVN. People suffering from sickle cell anemia are also susceptible to AVN, as abnormal red blood cells clump inside the bone and obstruct blood flow. Deprived of blood's important nutrients, including oxygen, tissues fail to survive and begin to break down, causing necrosis.
BMAC Procedure offers Rapid Recovery.
After the procedure, patients can bear full weight after a week, and resume exertional physical activity at six months. “The idea is that once the stem cells are in the cavity, they will take nourishment from any remaining vasculature or blood supply and start to grow, differentiating into bone tissue,” says Dr. Einhorn. “This new bone tissue should then use the surrounding necrosed tissue as a scaffold, putting living bone back where it belongs.”
Groundbreaking Treatment Based on Extensive Research.
Dr. Einhorn's research at the Boston University Orthopaedic Research Lab has been funded by the National Institutes of Health since 1990. Working closely with a team of 50 physicians and scientists, including orthopaedic surgeons, Ph.D. scientists, graduate students, orthopaedic doctors in training, nurse practitioners, and post doctorate fellows, Dr. Einhorn continues to research and develop new therapies to enhance th
