| What are the standard views for the lumbar spine (3)? name the additional views (3) | Standard views - 1.AP lumbar 2. Lateral Lumbar 3.Angulated AP L5-S1 Spot Additional Views 1.Oblique Lumbar 2.Lateral L5-S1 Spot 3.Other Pelvic, Sacral, Coccyx, and SI Joint views |
| AP Lumbar (aka AP Lumbopelvic) is shoot on a _______ film? | 14 in by 17 in film |
| On a AP lumbar the anterior aspect of the SI joints are _____(lateral or medial)? | Anterior aspect of SI joints are Lateral, the posterior aspect of SI joints are medial |
| What type of projection should be used the best visualize the sacrum? | Spot projection |
| What is well visualized on a Lateral Lumbar? | Disc spaces and IVF's |
| On a Lateral Lumbar view the approximation of the SP's are called? | Baastrup's Syndrom |
| An Angulated L5/S1 Spot projection is used to visualize? | To visualize L5 disc, SI joints, and sacral foramina, it can be shot AP or PA |
| Lumbar Obliques are primarily utilized to asses what? | The Pars Interarticularis and facet joints = Scotty Dog, (not the IVF's like in the Cervical spine) |
| "Scotty Dog" What is the eye, the nose, the ear, the neck, the body, the forefoot? | eye = pedicle, nose = TVP, Ear = superior articular process Neck = Pars, body = Laminae, Forefoot = Inferior articular process |
| What view is used to assess spondylolysis (pars fracture)? | Oblique lumbar (this does not imply anterior displacement - spondylolisthesis) |
| Rule: When viewing the lumbar oblique, the structures can be divided by the vertebral body MARGIN rather than dividing the vertebral body in half as was done in the cervical spine | Any structure on the side of the marker is anatomically located on that side. NO Exceptions |
| ***When viewing a Posterior Oblique Lumbar what structures do you see? | Same side structures |
| ***When viewing a Anterior Oblique Lumbar what structures do you see? | Opposite side structures (opposite from cervicals) |
| T/F Viewing a Left Posterior Lumbar Oblique you see a Right Pars? | False, Posteriors are same side structures |
| T/F Viewing a Right Anterior Lumbar Oblique you see a Right Pars? | False, anteriors are opposite side |
| T/F you see the same structures with a LPO lumbar and a RAO lumbar? | True, see the Left pars on both |
| What structure is seen with a RPO lumbar, how about a LAO lumbar? | Same thing Right structures. (posterior = same side, anterior = opposite side)....I think I've beat this to death |
