Plain radiographs of the lumbar vertebrae, anteroposterior (Left) and lateral neutral (Right) view, showing grade I degenerative spondylolisthesis at L2-L3, L3-L4 and L4-L5 associated with disc space narrowing. The pedicle-facet angles were 127  at L2, 126  at L3, 123  at L4, and 124  at L5. The amount of slip over L2-L3, L3-L4 and L4-L5 were 9 mm, 7 mm and 6 mm, respectively.

Plain radiography of the lumbar vertebrae revealed grade I degenerative spondylolisthesis at L2-L3, L3-L4 and L4-L5 (Figs. 1 and 2).
Flexion (Left) and extension (Right) view of the lumbar vertebrae showed a stable lumbar spine.

Plain radiography of the lumbar vertebrae revealed grade I degenerative spondylolisthesis at L2-L3, L3-L4 and L4-L5 (Figs. 1 and 2).
T2 weighted images of the Lumbar spine-Sagittal (A) and axial [L2-L3 (B), L3-L4 (C), L4-L5 (D), L5-S1 (E)] demonstrating L2 to L5 diffuse disc bulge, bilateral facet joint degeneration and ligamentum flavum hypertrophy resulting in the severe central canal, subarticular zones and exit foramina stenosis. At L5/S1 level, central and left paracentral disc protrusion has resulted in moderate narrowing of the central canal and bilateral subarticular zones (i.e. the left subarticular zone is narrowed to a greater degree).

L2-S1 decompression laminectomy and posterior lateral fusion of L2-S1 with posterior instrumentation and bone graft was performed to decompress the spinal cord and stabilise the lumbar spine (Figs. 4).
