Outline of Final Research Achievements

The present study aimed at developing a simulation system that enables pre-operative planning of the most appropriate operative strategy for pectus excavatum. Though correction of the deformed chest is mainly conducted with the placement of correction bars to the thorax, this method doesn’t necessarily guarantee optimal results, because the thoraxes present anatomical variation. To achieve optimal results, it is essential to predict the effect of the bar-placement taking into consideration the individual variation of patients, which we set as the goal of the present study.
We first developed a system to produce three-dimensional graphic models refereeing to patients’ data. Then we found a method to assign appropriate material properties to each component of the models. These systems enables surgeons to predict transformation patterns thoraxes would take through operation and select the best operative strategy among the possible ones.
