Biomechanical Stability Analysis of a Stand‐alone Cage Static and Rotational‐dynamic Plate in a Two‐level Cervical Fusion Construct

摘要

ObjectiveTo test the following hypotheses: (i) anterior cervical discetomy and fusion (ACDF) using stand‐alone interbody spacers will significantly reduce the range of motion from intact spine; and (ii) the use of a static or a rotational‐dynamic plate will significantly augment the stability of stand‐alone interbody spacers, with similar beneficial effect when compared to each other.
