An integrated computer-aided approach for parametric investigation of anatomic plate design

Abstract

ABSTRACT Personalized anatomic plate is used in the surgical treatment of femoral fracture for the good matching between individual femur and plate. However, the development process of personalized plate is time-consuming and laborious at present due to anatomic and fracture differences between individuals. To improve the efficiency and quality of plate design, this study proposes an integrated computer-aided approach for parametric investigation of anatomic plate design. Based on the constraint deformation of femur template, a reference model was constructed, and major fracture segments were quickly restored to each original anatomic region by rigid registration to the reference model. The experimental results indicate that personalized anatomic plates can be constructed and edited quickly and intuitively with semantic parameters in high level, and contribute to the improvement of design efficiency and quality of customized plates for individuals.
