Question | Answer |
AP Axial Sacrum CR | 2" superior to pubic symphesis, 15 degrees cephalic (20 on females) |
AP Axial Coccyx CR | 2" superior to pubic symphesis, 10 degrees caudal |
AP Axial SI Joints | 1.5" superior to pubic symphesis, 30-35 degrees cephalic (35 for females) |
oblique SI joint CR | 1" medial to raised ASIS, pt oblique 25-30 degrees |
Lateral sacrum CR | at level of ASIS and 3.5" posterior |
Lateral coccyx CR | 2" inferior and 3.5" posterior to ASIS |
Lateral sacrum/coccyx CR | 2" inferior and 3.5" posterior to ASIS |
Lumbar routine | AP, 2 obliques, Lateral and L5S1 spot |
AP Lumbar CR | at iliac crest (for lumbosacral) |
Lumbar oblique CR | 2" medial to raised ASIS and 1.5" above crest, 45 degree oblique |
Lateral Lumbar CR | at iliac crest (only left laterals) |
Lat L5S1 Spot CR | 2" posterior to ASIS and 1.5" inferior to iliac crest |
kyphosis | abnormal forward curve of T spine |
scoliosis | abnormal lateral curve of the spine |
spondylolisthesis | one vertebra slips forward on the vertebra below |
fibrocartilage disks | between 2 bodies of vertebrae |
spina bifida | arch of the vertebrae fails to meet at the midline |
slipped disk | herniated nucleus pulposus HNP |
HNP | pulpy nucleus ruptures impinging on spinal nerve |
last moveable joint in lower spine | lumbosacral junction (L5S1) |
pars interarticularis | portion of lamina between 2 articular processes, commonly fx |
zygapophyseal joint | formed by inferior articular process of one vertebra and superior articular process of one below it, seen on oblique |
intervertebral foramen | formed by inf vertebral notch of one vertebra and superior vertebral notch of other, seen on lat |
sacrum | 5 segments, female more acute |
sacral promontory | anterior border |
pelvic sacral foramina | 4 pairs |
sacral hiatus | between cornu |
sacral cornu | sacral horn |
medial sacral crest | ridge on posterior surface |
sacralization | L5 fuses with S1, 4 lumbar |
lumbarization | S1 and S2 don't fuse, 6 lumbar |
coccyx | 3-5 (usually 4) coccageal segments, males curve more forward |
reasons for not collimating too much for AP Lumbar | looking for metastic rib lesions, rib fractures, kidney stones |
AP Axial L5S1 (special view) | CR 30-35 degrees cephalad, 1.5" above pubic symphesis |
scoliosis series (basic) | ap and lat erect, cR 1-2" below crest |
scoliosis series (special) | ap ferguson, ap right and left bending, lat flexion and extension |
Ferguson | 1st view standing normal, 2nd with one side elevated |
dog front leg | inf articular process |
dog ear | sup articular process |
nose | transverse process |
eye | pedicle |
neck | pars interarticularis |
spondylolysis | breaking down of vertebra |
lordotic (secondary) curves | cervical and lumbar, convex anteriorly |
kyphotic (primary) curves | thoracic and pelvic, concave anteriorly |
lordosis | abnormal increase in anterior convexity of lumbar or cervical curve |
L4, L5 | level of iliac crest |
S1, S2 | level of ASIS |
process extending laterally and posteriorly from the body | pedicles |
process extending posteriorly from the junction of both laminae | spinous process |
process extending laterally from the pedicle-laminae junction | transverse process |
articular processes | zygapophyses |
solid anterior part of vertebrae | body |
connects the transverse process with the spinous process | laminae |
