A Study of the Dynamic Anterior Cervical Plate Implant by Computer Aided Virtual Engineering Method

Abstract

The convenience of dynamic anterior cervical PMMA biomaterial placement of spinal implants is considered by finite element modeling. The maximum fatigue behavior was also studied in surface coated Ti-5A1-2.55n spinal screw-rods. Anterior cervical biomaterial plates reduce the hazard for spinal cord injury and provide outstanding fixation for the anterior column, to stop the relocation and slackening of screws-rods by a cross-split screw crown that may be fastened into the biomaterial plate. This article reports about the hollow Ti-5Al-2.55n screw and cervical biomaterial PMMA plate system. The flexion movement of the spine implant was modeled to control the stresses and strains of the bone and screw interfaces under the external forces, as well as motion of the vertebrae by finite element modeling. This computational engineering analysis is aimed to support patients suffering anterior cervical arthrodesis after degenerative disease or trauma. The data from this research may provide an essential base to estimate the stabilization quality. A model for the biomaterial between C4 and C6 segments of vertebrae of cervical spine was obtained. Study of the cervical biomaterial implant provides instantaneous secure fixation virtual experiment with minimal complications, before the real implant surgery, using computer aided virtual engineering.
