Objective: Hybrid stabilization with a dynamic implant has been suggested to avoid adjacent segment disease by creating a smoother transition zone from the instrumented segments to the untreated levels above. This study evaluates ex vivo the range of motion (RoM) to characterize the transition zones[for full text, please go to the a.m. URL]
