A subject close to my heart.
Be clear, this is just general conversation between you and a retired pilot.
I'm puzzled about why it is thought the vertebra is displaced per se.
Significant Edit:
The front looks in line, with no sign of significant spurs. The 'leading edges' of L5 and S1 are naturally very pronounced.
I can only assume the hollowing in at the rear is the intervertebral foramen - on the red cut scan line - viewed from the opposite side . It will show as white.
