Avascular Necrosis of the Hip: Dr. Lox Treats with Stem Cells

Dr. Dennis Lox a Sports and Regenerative Medicine Specialist has treated his share of difficult cases. Avascular necrosis (AVN) also referred to as ischemic necrosis and osteonecrosis, occurs when the blood flood flow to the bone is disrupted leading to bone cell death (necrosis). The problem with this is that if the necrotic zone collapses, it leads to rapid secondary osteoarthritis (joint destruction). The leading cause of AVN is trauma. Many famous athlete have had avascular necrosis of the hip (Bo Jackson and Brett Favre). Bo Jackson never played professional football again after he was tackled and injured his hip. Favre was lucky, the secondary arthritis never set in, and his avascular necrosis of the hip remained stable. Despite occasional hip pain.

The prognosis for Brett Favre is eventual osteoarthritis of his hip. The utility of stem cells in the management of Avascular Necrosis (AVN) is multifold. Acute effects are aimed at increasing blood flow through angiogenesis. Secondly, the stem cells may produce new bone cells via differentiation, thirdly, the stem cells may exert a positive effect on the joint, preventing secondary osteoarthritis. All three combined is excellent. Yet, just preventing the secondary arthritis may be enough to keep a patient functional and prevent a total hip joint replacement.

When a patient presents with hip AVN, all these considerations are weighed and measured. It is through such an approach that optimal out comes occurs.
