Abstract
To facilitate cervical fusion, cervical cages filled with bone or bone substitute are inserted between the vertebrae. To improve the subsidence of the cage and to avoid its post-surgical migration, design optimization concept is being employed in the present work. In this study, finite element method is being used to design several cervical cages with varying shapes and sizes. The cages are designed using Solid modeling software. Finite element analysis (FEA) optimization is done by varying the material properties as well as shapes and sizes of the cage. Stress analysis has been performed using FEA in the cervical vertebrae C3-C4 for the different types of cages.
