Wies, MPH and Laura Raymond, MA This technology overview addressed four questions that compared the difference in outcomes between patients undergoing cervical disc arthroplasty with patients undergoing anterior cervical diskectomy fusion. Most studies did not either report or conduct the appropriate statistical analyses to examine predictive characteristics in patients with successful clinical outcomes. Most studies were inconclusive or unreliable regarding clinical outcomes and revision and/or complication rates in patients who present with neck and/or arm pain. No significant difference in the length of hospital stay was reported; however, two studies included in the overview reported that patients treated with cervical disc arthroplasty returned to work in significantly fewer days (range, 14 to 16 days) than did patients treated with anterior cervical diskectomy fusion.
