Overview

A prospective, multicenter post-market clinical follow-up study to evaluate the 10-year long-term safety and effectiveness of the Simplify Disc at two levels in subjects who were enrolled in the IDE study (NCT03123549) and/or post approval study (NCT04980378).

Interventions

  • Device NuVasive Simplify Cervical Artificial Disc
    Simplify Disc is a weight-bearing cervical artificial disc implant consisting of PEEK (polyetheretherketone) endplates and one semi-constrained, fully articulating, mobile Zirconia Toughened Alumina ceramic (ZTA) core.

Primary outcome measures

  • Clinical Composite Success Rate [Time frame: 10 years]
Secondary outcome measures (12)
  • Percentage of subjects meeting the minimal clinically important difference (MCID) for NDI at each annual timepoint [Time frame: 10 years]
  • Percentage of subjects meeting MCID for neck and arm pain questionnaire for each of the following pain locations: neck pain, arm pain, left arm pain, right arm pain. [Time frame: 10 years]
  • Motor status at each annual timepoint compared to baseline [Time frame: 10 years]
  • Sensory status at each annual timepoint compared to baseline [Time frame: 10 years]
  • SF-36® Health Survey at each annual timepoint compared to baseline [Time frame: 10 years]
  • Dysphagia Handicap Index1 (DHI) at each annual timepoint compared to baseline [Time frame: 10 years]
  • Disc height at each annual timepoint will be compared to baseline [Time frame: 10 years]
  • Adjacent level disc degeneration (ALDD) at each annual timepoint will be compared to baseline [Time frame: 10 years]
  • Displacement or migration of the Simplify Disc at each annual timepoint will be compared to the post-op timepoint in the IDE study (NCT03123549) [Time frame: 10 years]
  • Range of motion (ROM) at each annual timepoint compared to baseline [Time frame: 10 years]
  • Rate of adverse events attributable to Simplify Disc, or use of additional NuVasive instruments, implants, or technologies at each annual timepoint [Time frame: 10 years]
  • Patient satisfaction and perceived effect at each annual timepoint [Time frame: 10 years]
