The most prolific author was Dr. Todd J Albert (n = 7), with 1, 312 citations. 67 patients were included in this prospective randomized trial. At follow up the percentage of patients who were totally pain-free was significantly higher in the TDR group versus the fusion group (38% vs 15%; p<0. Balderston JR, Gertz ZM, McIntosh T, et al. They treat patients who have had unsuccessful treatment and are still suffering. Polymer-on-metal or metal-on-polymer total disc arthroplasty: Does it make a difference? In this study, we propose to use bibliometric methods to highlight the characteristics of the 100 most-cited articles on ACDF, especially in terms of research hotspots and focus.
Also, there is open surgery via anterior and posterior methods and tether procedures. Laminectomy, Corpectomy, Kyphoplasty, Discectomy, and Spinal Fusion are the primary types of minimally invasive surgical procedures. The authors concluded that they had demonstrated statistical superiority of the Maverick arthroplasty versus fusion on key clinical outcomes including improved physical function, reduced pain, and earlier return to work. Park SJ, Kang KJ, Shin SK, et al. Posterior instrumentation was utilized in 55. An evidence-based medicine approach in determining factors that may affect outcome in lumbar total disc replacement.
