Evaluating the differences between 1D 2D and 3D occupying ratios in reflecting the JOA score in cervical ossification of the posterior longitudinal ligament

摘要

BackgroundTo compare the differences between the one-dimensional (1D) length, two-dimensional (2D) area, and three-dimensional (3D) volume occupying ratios, and to assess the difference between the central and peripheral types of ossification of the posterior longitudinal ligament (OPLL).
