Dr Schroeder has been a Foot & Ankle Surgeon for over 30 years. He has surgically placed thousands and thousands of metallic implants over his career. He became more and more aware of reactions to these implants as time went on. Not just local reactions, but disabling systemic reactions, necessitating the need to remove the implants. Over the past decade or so Dr Schroeder has removed over 1,000 implants in over 400 patients. He presented to the FDA in 2019 on the Systematic Effects of Metal Allergies. He has presented in London and Australia and numerous other international conferences around the world. In his surgical center he tested significant galvanic current changes before and after removing metal implants from the body in relation to dental metals. He is in the process of writing up this study with colleagues. He is in contact with Doctors and Scientists around the world regarding metal allergies and reactions.
