Abstract
Staples made of shape memory alloy have been used to treated idiopathic scoliosis by growth modulation (Betz and coll., 2003). The technique of this surgery is minimally invasive and uses the force generated by staple in order to apply a force to the vertebral growth plates. In this master project, it is postulated that a better knowledge of the mechanical behavior of staples and of the mechanobiologic behavior of growing bone tissue in growth will make it possible to improve the results obtained for the patients. This project is a pilot study aiming at determining the methodology which will be followed at the time of future studies. The first specific objective of this project is to develop and validate experimental protocols for a surgery by staple on an animal model and a test bench to measure the force delivered by staple made with shape memory alloy. The second objective is to develop methods of analysis for the characterization of the growth modulation by the use of staples and to make recommendations for the future studies.
