Total lumbar disc replacements (TDRs) are designed to restore kinematics of a degenerated segment . Compared to the fusion of the segment, disc replacements may prevent adjacent segment degeneration. Various designs have been proposed for lumbar TDR; however most of these require an anterior surgical intervention for placement. Post-surgery facet pain and degeneration are shown to occur. Complicated surgical procedure and difficulty in revision are other deficiencies of anterior discs concept. Posterior disc designs are novel alternatives for restoring kinematics across the implanted spine and posses the ability to overcome the limitations of anterior lumbar arthroplasty.
