Finite element analysis of the effect of plate placement angle on cervical spine stability in anterior cervical fusion surgery / 中国骨伤

ABSTRACT

OBJECTIVE@#Using the method of finite element analysis, to compare the biomechanical properties between the plate deviating from the long axis of the cervical spine and the standard placement of the plate in the anterior cervical fusion surgery.@*METHODS@#A healthy female volunteer was selected and CT scan (C@*RESULTS@#The lower cervical spine (C@*CONCLUSION@#Little effect on the mechanical stability of the cervical spine was anticipated when the anterior cervical plate was not perfectly aligned with the long axis of the cervical spine. If the tilt of the plate in clinical surgery is less than 20°, there is no need to readjust the position of the plate.
