Lateral-view functional plain X-ray in the older brother showing slight instability between L5/S1 flexion and extension (a, b). Magnetic resonance images showing the L5 vertebra slipped anteriorly on S1 and the L5/S1 disc bulging apparent on the sagittal slice (arrow) (c). MRI also showed serious canal stenosis at L5/S1 with disc bulging apparent on the axial slice (d). Computed tomography with myelogram showed a vertically displaced anterior slip to S1, a round-shaped S1 cranial endplate and spinal canal stenosis (arrow) with dysplastic bilateral facets at L5/S1 (e, f)
