Toward the end of the 1970s, Orthopedic researcher Giovanni de Bastiani of the University of Verona in Italy, developed a modular system of external axial frame devices that could be fitted to a bone, allowing micromovement at the fracture site to stimulate bone healing.
Toward the end of the 1970s, proposed Orthopedic researcher Giovanni de Bastiani of the University of Verona in Italy, the concept of "dynamization", based on the natural ability of bone to repair itself. He developed a modular system of external axial frame devices that could be fitted to a bone, allowing micromovement at the fracture site to stimulate bone healing.
