Biomechanical Effect of Constraint in Lumbar Total Disc Replacement: A Study With Finite Element Analysis

Biomechanical effect of implantation of an artificial disc (AD) was investigated using the nonlinear three-dimensional finite element model of L4-L5. The SB CHARITE and the Prodisc were chosen as the representative prosthesis of unconstrained and constrained ADs (UADs and CADs) and compared with the...
