Abstract
Cervical interbody fusion cage is used widely in spinal fusion surgery to treat cervical degenerative disc disease in order to form a connection of adjacent bone levels. Over time, the intensity of bone changes at the site of intervertebral disc replacement surgery occurs because of the stiffness of the cage. The stress distribution changed from previously, which may result in cage subsidence. According to research of the design and development of interbody fusion cage that affects the stress distribution under static load in four motions are still limited, the objectives of this research are to design and construct an accurate finite element model of the interbody fusion cages and compared the efficacy of those cages. Three models of interbody fusion cages were designed in the material type of Titanium in different shapes and geometric sizes. Cages were analyzed for the stress distribution values compared with the intervertebral disc in four motions under static loads. The results showed that different shapes and geometric sizes of interbody fusion cages effects directly on the stress distribution. The Cage 1 model provides a better stress distribution in the directions of flexion, extension and axial rotation. However, the development of interbody fusion cages still should be more investigated. Further analysis of the strain and range of motion (ROM) will contribute
to gaining more proper and accurate results.
