Abstract:
The biomechanical properties of the lumbar pedicle screw technique, cortical bone trajectory screw technique, and modified cortical bone trajectory screw technique when used individually in internal fixation systems and their effects on neighboring segments have been studied. However, there are fewer studies on the combined use of the modified cortical bone trajectory screw technique and the cortical bone trajectory screw technique. This paper focuses on analyzing the stresses in the internal fixation system when the modified and traditional cortical bone trajectory screw techniques are applied jointly, and the effects on the adjacent segments using the finite element analysis.
