Case Number 109089 - Biodegradable, Single-Crystal Magnesium Medical Implant
Contact: Doug Nienaber
Description: About 7 million broken bone incidents are treated in the United States each year. The average person in a developed country experiences two such incidents in a lifetime. Pins, screws, rods, and plates are regularly required to treat these injuries.
Magnesium is a robust metal, a dietary nutrient used by the body, and a substance that naturally biodegrades within the body. That said, for strength, magnesium-based implants are typically doped or alloyed with elements that can be toxic.
Researchers at the University of Cincinnati, in collaboration with a colleague from Hannover Medical School in Hannover, Germany, have made individual crystals and agglomerates of single crystals of pure magnesium that show physical and chemical properties suitable for medical use without doping or alloy.
Provisional patent pending.
