Five-year results of cervical total disc replacement (cTDR) compared with anterior discectomy and fusion (ACDF) to treat 2-level symptomatic degenerative disc disease: a prospective, randomized, controlled, multicenter investigational device exemption clinical trial have been published by the Journal of Neurosurgery: Spine. Study results indicated overall success rates at 5 years of 61% and 31% for the cTDR and ACDF groups, respectively.
While single-level long-term data have been published on the Pro-Disc-C (DePuy Synthes), Bryan and Prestige ST devices (latter two Medtronic), this paper represents the first report on 5-year Investigational Device Exemption data for 2-level cervical arthroplasty.
Christophe Lavigne, President and CEO of LDR, commented, “We believe that this publication will further support the movement among insurance payers to expand coverage to include two-level cervical disc replacement, allowing more surgeons and patients to benefit from the procedure.”
