Non-Surgical Care For Osteonecrosis In Winter Park, FL

Are You a Regenexx Candidate?

Avoid Joint Replacement Surgery with Regenexx.

Avascular necrosis (AVN) or Osteonecrosis is death of bone tissue that occurs when healthy stem cells in a bone die off, become sick, or are too few in number to keep up with normal wear and tear. The single most common cause of osteonecrosis is use of oral steroids like Prednisone that in high doses stunt your body’s natural healing ability. While oral steroids can reduce swelling, they are frequently given in such high doses that they can cause cells that help to maintain your bone to actually die off or become stunned.

Risky pain-management strategies and harmful steroid injections can temporarily manage pain, but if AVN occurs in your body, ultimately invasive joint replacement is highly likely. Regenexx has been treating AVN with precise injections of your customized cells longer than anyone else in the U.S. and has good results treating certain lesions and stopping the progression of the AVN.

During this outpatient procedure, our expert physicians use precise image guidance to inject custom concentrations of your body’s natural healing mechanisms into the exact areas of damage to provide the support needed to prevent further damage. Call our patient care coordinators today to get started on your path to recovery.
