 There is severe dextroscoliosis centered at L3-L4 which is unchanged from the recent radiograph of 5/4/2015. There is leftward subluxation of L2 relative to L3 measuring 10 mm and L3 relative to L4 measuring 9 mm. Multilevel severe degenerative disc disease has progressed with increased disc space loss at L1-L2. Expected progression of endplate degenerative changes which are slightly worse on the prior exam. Schmorl's node along the inferior endplates of L1 and L5 are new from the prior exam. Multilevel severe facet joint arthropathy with effusions is increased since the prior exam. Signal within the distal cord is normal with the conus ending at L1. A lateral disc protrusion at T10-T11 is new from the prior exam as seen on the lateral views.T12-L1: New left foraminal protrusion without significant spinal or neural foraminal stenosis.L1-L2: Diffuse disc bulge, asymmetric to the left is new. Ligamentum flavum thickening. Right facet arthropathy is increased with increased moderate right neural foraminal stenosis. No spinal stenosis.L2-L3: Diffuse disc bulge is increased. Ligamentum flavum thickening. Mild spinal stenosis is unchanged. No neural foraminal stenosis.L3-L4: Diffuse disc bulge with small annular tear which is new from the prior exam. Moderate spinal stenosis is unchanged. Moderate to severe left neural foraminal stenosis is unchanged. Facet hypertrophy has increased since the prior exam, encroaching on the left lateral recess, with increased ligamentum flavum thickening.L4-L5: Diffuse disc bulge is unchanged. Moderate left neural foraminal stenosis.L5-S1: Diffuse disc bulge is unchanged. Mild right and moderate left neural foraminal stenosis. No central stenosis.
Progression of spondylosis most notably at L1-L2. Up to moderate-severe left foraminal stenosis at L3-L4 with moderate central spinal canal stenosis.
