Dynamization (dynamic loading and controlled motion at the fracture site) is considered a controversial and evolving issue, besides the positive functional results observed both in experimental studies based on animal models, and in human clinical cases in the last 30 years. Currently one crucial matter is to understand the biomechanical, biological and physiological effects of dynamization on the bone healing process, in order to show its safety and effectiveness. 

The Orthofix history began at the end of the 70s in Italy with the work of orthopedic researcher Giovanni De Bastiani. He proposed the concept of “dynamization” and developed a modular external fixation device designed to allow the release of axial forces at the proper time during the healing process, thus transferring a progressive load to the fracture site. After this first device, other devices were developed by Orthofix to better satisfy patients’ and doctors’ needs.

Stability does not mean rigidity. Medical philosophy has evolved from the aim to eliminate micromotion between the bony fragments to the idea of controlling it. Micromotion is necessary for external callus formation, and therefore for a functional bone healing. External fixation offers the opportunity to control both micromovement and load at the fracture site, which corresponds to the concept of dynamization.
