Validation of a non invasive simulation tool for the effective planning of scoliosis surgery
EF 2011-12
Résumé
The technological innovations of the past decades in 3D modeling and numerical simulation have had a significant impact on treatment planning. Currently, surgeons express their need for planning and simulating their surgical maneuvers on numerical models. In this context, surgery simulators are being developed in different fields such as cardiology, neurology and orthopedics. Such numerical simulations are used for instance in plastic and reconstructive facial surgery. Our team is currently developing a software system for the simulation of spinal surgery, for the optimal planning of surgical procedures intended to correct the spinal deformities. However, this simulator is not able to predict the treatment's effect on the patient's external appearance which is the main concern of adolescents with scoliosis.
Thanks to the support of an NSERC Strategic grant, we have demonstrated the feasibility of simulating the effect of a spinal surgical correction on the external shape of the trunk in the treatment of adolescent idiopathic scoliosis. A physical model of the deformable tissues of the trunk including skin, fat and muscles was first developed. Then, a generalized particle system minimizing an elastic potential energy by computing forces that preserve distance, area and volume constraints was used to simulate the physical behaviour of the soft tissues after spinal surgical treatment. The objective of this Phase I I2I proposal is to validate the proposed system on real data of a representative cohort of patients with different types of scoliosis. A simulation of the correction, not only on the bone structures but also on the external appearance, will allow the clinician to illustrate to the patient the potential result of the surgery and would help in the decision to accept or refuse a surgery that could improve his/her appearance. Thus, this proposal has the potential to lead to a non invasive predictive tool for the surgical treatment of scoliosis which will increase the quality of life of the patient by using non invasive imaging modalities and the Canadian economy by reduction in health care costs, and finally by the commercialization of the resulting technologies by our supporting industrial partners.
