In a comparison study, researchers from Texas Back Institute Research Foundation found two-level total disc replacement, combined anterior/posterior 360° fusion and a hybrid combination of total disc replacement at one level and fusion at another were all successful options for treating patients with two-level symptomatic disc degeneration. “Two-level total disc replacement, hybrid and fusion patients all significantly improved over [patients’] preoperative status, and considering newer data showing lesser percentage of adjacent segment surgery with disc replacement surgery, this becomes an even stronger argument for motion preservation over fusion,” study researcher Richard D. Guyer, MD, who presented the findings at SpineWeek 2012, told Orthopedics Today. Source: Healio.com
