Sabrina had pain in her right hand thumb joint (an arthritic thumb). She also had limited range of motion. And then in her left hand, she had Dupuytren’s contracture, a condition that causes permanent bending of the fingers, typically the ring and little fingers, due to thickening and shortening of the palmar fascia, which is the connective tissue in the palm of the hand. Rowen injects ozone into Sabrina’s hands. Sabrina’s pain goes away, she can now move her right hand thumb, and the Dupuytren’s contracture on her left hand is totally gone. Sabrina says it is “absolutely excellent.”
