structures shown for L-spine obliques | articular process and zygapophseal joints of side down |
the pedicle is seen anterior on the body for an oblique L-spine, meaning: | the patient is under rotated |
if the pedicle is posterior on the body for an oblique L-spine, the patient is: | over-rotated |
