The so-called gold standard for definitive operative treatment of discogenic pain is interbody arthrodesis1. Adjacent-level degeneration as well as incomplete pain resolution despite radiographic evidence of fusion has led to dissatisfaction with this technique and became the impetus to develop other surgical options for the treatment of back pain2-5. With the U.S. Food and Drug Administration approval of the CHARITÉ Total Disc (DePuy Spine, Raynham, Massachusetts) in 2004, total disc replacement became a treatment option for the painful degenerative lumbar disc in the United States. Proponents of this procedure believe that the maintenance of disc height and the preservation of segment motion will facilitate the resumption of more normal activities, decrease pain, and prevent adjacent-segment disease.
