• Satisfactory sagittal spinal alignment but there is a severely congenitally stenotic canal ( less than 10 to 17mm). The L5 vertebra is transitional, being attached to the sacrum via bilateral enlarged transverse processes and pseudarthroses.
• There is early degenerative change at the L4-L5 and L5-S1 disc levels manifest by mild heterogeneous loss of T2W nuclear SI with a minor bulge at L4/L5 which is resulting in fairly severe thecal sac and possible cauda equina compression.
• At L5/S1 there is a small circumferential disc bulge with a focal right sided paracentral disc protrusion which in association with the spondylotic changes is leading to compression of the right S1 descending nerve root.
