Objective To introduce a new grading system of lumbar central canal stenosis, evaluate its reliabilities, and compare it to the cross-sectional area and anterior-posterior diameter of the dural sac. Materials and methods Lumbar central canal stenosis is defined as obliteration of the anterior CSF sp...
