Abstract(s)

The human skeleton is formed by living tissues that react to loads and ensures the support of the remaining tissues of human body like muscles, ligaments, tendons, etc. However, its integrity can be compromised due to fractures or injuries of the bone tissue that require orthopedic surgery and immobilization methods, such as external fixators, intramedullary nail or osteosynthesis plates.One of the most important characteristics of living tissue is its capacity of self-regeneration. It is a complex process that implies several mechanisms during the consolidation time. Therefore, the knowledge of the involved mechanisms and their interdependence on external factors, will allow accelerating the regeneration process and contributing to the success of the rehabilitation process. Several techniques have been developed to characterizing characterize the mechanical loads acting in fractured bone to better understand the fracture consolidation and obtain useful information for the orthopedic doctors. This information is relevant to enable each patient follow-up and optimize the clinic procedures. As such, it is important to understand what happens during fracture consolidation to predict the necessary structural immobilization time and mechanical stimulus which shorten the healing process. The purpose of this work is twofold: primarily, to study the consolidation process using different immobilization systems, and secondarily, to explore the necessary time for bone consolidation by recording the relevant mechanical parameters time story.
