Load-sharing between anterior and posterior elements in a lumbar motion segment implanted with an artificial disc.


STUDY DESIGN A nonlinear three-dimensional finite element model of the osteoligamentous L3-L4 motion segment was used to predict changes in posterior element loads as a function of disc implantation and associated surgical procedures. OBJECTIVES To evaluate the effects of disc implantation on the biomechanics of the posterior spinal elements (including… (More)
