| Inverted magnified image of L5 showing the hat like contour of L5 vertebra. |
Picture of Napoleon wearing his hat in the inset. Right side image is inverted to show the hat like appearance of L5 vertebra more clearly.
The reason for this is due to spondylolysis of L5 (defects in pars interarticularis) and signficant anterolisthesis (here grade II) over S1 vertebra, which is showing in this lateral radiograph.
