Cervical Posterior Foraminotomy’s Effect on Segmental Range of Motion in the Setting of Total Disc Arthroplasty

Abstract

Total disc replacement (TDR) is gaining popularity for the treatment of cervical radiculopathy. In spite of a proven track record, recurrent same level radiculopathy and adjacent level disease remain prevalent with significant clinical problems. Posterior foraminotomy offers the ability to decompress cervical nerves roots while avoiding the need to extend a previous fusion or revise an arthroplasty to a fusion. However, the safety of a foraminotomy in the setting of TDR is unknown.
