I have been practicing the concept of Prolotherapy for almost 20 years. For the last 5 or so years, I really thought I was getting it. Ravin, Cantieri, and Pasquarello; however, have opened the door wide and shown us the way. This is the definitive guide not only to injection techniques; but, also to the anatomic, pharmaceutical, biomechanical and manipulative aspects of Prolotherapy and Orthopaedic medicine. The illustrations alone are incredibly useful. I know of no comparable volume in any area of medicine.
