MRI of the lumbosacral vertebral column was performed using a 0.2 Tesla unit (Esaote Grande, Genova). (a) T2-weighted sagittal plane, (b) T1-weighted sagittal plane, (c) T2-weighted transverse plane and (d) T1-weighted transverse plane. The L7-S1 intervertebral disc had low signal intensity in T2-weighted images, consistent with mild disc degeneration. Slight protrusion of the disc was also present. There was downward elongation of the sacral lamina into the vertebral canal. Dorsal and ventral stenosis of the vertebral canal with compression of the nerve roots at the level of the sacrum was also observed (arrowheads). New bone formation observed bilaterally and ventrally to the lumbosacral joint indicated the presence of spondylosis deformans. A diagnosis of degenerative lumbosacral stenosis was made

Radiography and MRI (0.2 Tesla unit; Esaote Grande) of the lumbosacral vertebral column were consistent with mild DLSS (Figure 1), and lumbosacral decompressive surgery was recommended.
Laterolateral radiography of the lumbosacral region. Notice L7-S1 spondylolisthesis (*), shortening of the lamina of L7 and fracture of the L7 articular facets (arrowhead)

A lateral radiograph identified L7-S1 traumatic spondylolisthesis, shortening of the lamina of L7 and fracture of the L7 articular facets (Figure 2).
Postoperative (a) laterolateral and (b) ventrodorsal radiographs of the lumbosacral region. Vertebral stabilisation has been achieved using screws and polymethylmethacrylate

Postoperative radiographs showed appropriate placement of screws and PMMA and vertebral realignment (Figure 3).
