Abstract_ Background MRI has proven to be an extremely valuable tool in the assessment of normal and pathological spinal anatomy. Accordingly it is commonly used to assess containment of discal material by the outer fibers of the anulus fibrosus and posterior longitudinal ligaments. Determination of such containment is important to determine candidacy for intradiscal techniques and has prognostic significance. The accuracy of MRI in detecting containment has been insufficiently documented. Methods The MRI s of fifty consecutive patients undergoing open lumbar microdiscectomy were prospectively evaluated for disc containment by a neuroradiologist and senior spinal surgeon using criteria available in the literature and the classification of Macnab McCulloch. An independent surgeon then performed the surgery and documented the actual containment status using the same
