Effects of spinal fixation devices on the motion segment mechanics

The finite-element technique is used to analyze the response of an intact ligamentous motion segment in axial compression mode. The three-dimensional nonlinear intact model is modified to simulate spinal stabilization using the Steffee screw-plate system. The results of the two models are compared to study the mechanics of load transfer across the Steffee system. The clinical implications of the results are described.<>
