Biomechanical Evaluation of the Kinematics of the Cadaver Lumbar Spine Following Disc Replacement With the Prodisc-L Prosthesis

Abstract

In cadaveric spines, ROM of operated and adjacent motion segments was preserved following ProDisc-L insertion. Excision of the anterior anulus may increase laxity, which is taken up by the restoration of disc height and lordosis, at the cost of a moderate loss of flexion/extension motion. Adjacent segment kinematics were unaffected following TDR.
