HOMO HOMINI MEDICUS. Eclectic surgeon, specialist in orthopedics and traumatology, pioneer of endoscopic surgery, radio-guided and minimally invasive robotics of the spine and small and large joints (knee, hip, foot, shoulder, elbow and wrist). He combines surgery with regenerative medicine, which he was the first to launch in Italy and Europe, with the use of FSV cells (Stromal Vascular Fraction, particularly rich in stem cells). Adolfo Panfili boasts a prestigious scientific and sporting curriculum of international importance, as well as being an expert in homeopathy, homotoxicology, phytotherapy, acupuncture and BEST chiropractic. Expressly commissioned by his teacher, Prof. Linus Pauling (multiple Nobel Prize winner), inventor of Orthomolecular medicine, he founded AIMO, (International Association of Orthomolecular Medicine), revisiting this science and merging it with other super-specialist branches, including regenerative medicine , aimed at restoring and repairing cartilage, bone and joint structures, vertebral discs, ligaments, tendons, etc.

Prof Adolfo Panfili, orthopedic surgeon with a very long CV of international standing. He is president of AIMO, the International Association of Orthomolecular Medicine of which he is the founder. He was a student of the double Nobel Prize winner Linus Pauling, inventor of Orthomolecular medicine. Prof Panfili has revisited and expanded this science by merging it with other sciences and techniques including the use of Stromal Vascular Fraction.

– He is Deputy Rector for International Relations as well as Dean of the Master's Faculty of Orthomolecular Sciences at the Popolare University of Milan;

– He is the first to have carried out minimally invasive robotic surgery in orthopedics in Italy with the Mazor system;

– He is Trainer and Proctor of Dtrax, a minimally invasive posterior cervical fusion and distraction system;

– He is the Director of various High Technology Minimally Invasive Spinal Surgery Centers accredited with the NHS and otherwise;

– He is the founder and director of the first Italian Center for Minimally Invasive Robotic Spine Surgery and one of the most eminent members of robotic surgery at the “International Academy for Robotic Spine Surgery”;

Prof. Panfili has been treating vertebrae, posture and nutrition in close synergy since the beginning of his thirty-year professional activity, both from a surgical and manipulative point of view, being among other things the first orthopedist in Europe to graduate in Best Chiropractic with Prof. Ted Morter, one of the best chiropractors in the world, of whom he was the best European student.

– He is currently a pioneer in the use and application of the Stromal Vascular Fraction in the field of well-being, anti-aging and longevity, with particular reference to orthopaedics, the spine and cervical, the aspect of cartilage damage for prevention of degenerative diseases of the hips, knees and intervertebral discs.
