What does the following info mean from my lumbar MRI results? T12-L1: 4.5 x 13 mm left paracentral disc protrusion that indents the thecal sac but produces no central canal or neur formation compromise? L4-5: bilateral L5 para defects allow for anterior subluxation of L4 by 1 cm; severe disc space narrowing with chronic endplate erosions and bilateral facet arthropathy are present; loss of disc spacing, the uncovered disc, and subluxation produce severe bilateral foraminal stenosis and flattening/compression of the right greater than the left extremity radiculopatgy L2-3: Mild retrolisthesis of L2, disc desiccation, and small left foraminal tear. The protrusion contacts, without displacing the L2 nerve root. Moderate levo-convex scholiosis centered at L4. Bilateral L4 pars defects also noted, with associated subluxation of 4 x 1 cm and advanced disc degeration of L4-5 L3-4 Minimal right and moderate left facet arthropathy. Mild ligamentous hyper trophy.
