52 patients with degenerative disc disease and resultant cervical radiculopathy and/or myelopathy were randomized to undergo a cervical disc arthroplasty with the NuNEC Cervical Arthroplasty System implant or the PRESTIGE LP Cervical Disc System implant. The study was conducted in order to determine if there was any significant difference between implants in surgical, clinical, or radiographical outcomes. Reported outcomes demonstrated no significant differences in measures of disability or pain at 3 years between the two devices. Additional, neither group demonstrated any implant-related complications, or needed reoperation.
