lumbar
| Question | Answer |
|---|---|
| what processes articulate to form the zygapophyseal joint? | superior and inferior articular processes |
| kyphotic curves of spine (curves back) | thoracic and pelvic |
| lordotic curves (curves forward) | cervical and lumbar |
| ___ have greater curvature of the sacrum | females |
| base of the sacrum is ___ Apex of the sacrum is ___ | at the top at the bottom *****same for coccyx |
| level of CR for AP lumbosacral | iliac crest |
| level of CR for only lumbar | 2" above iliac crest |
| special characteristic of lumbar vertebrae (part of lamina between articular processes) | pars interarticularis |
| anatomy of sacrum where L5 articulates | promontory |
| feature of the sacrum found near the apex. two small horn like projections | cornu |
| 4 anatomical features of the sacrum | promontory, foramen, cornu, canal. |
| intervertebral joints are cartilaginous, _____, and _____. | symphysis, and slightly movable. |
| Zygapophyseal joints are ____, ___, ____ | synovial, gliding, freely movable |
| level of iliac crest | L4-L5 |
| knees are flexed for AP lumbar spine in order to | reduce lordosis and place back on the table |
| what tissue feature should you see in Ap lumbar with correct exposure factors? | psoas muscles |
| angle for lateral L-spine if spine is curved | 5-8 caudad |
| lateral L-spine demonstrates | intervertebral foramina |
| Intervertebral foramina are best seen in which view | lateral L-spine |
| two good ways to see if there is no rotation on lateral L-spine | if joint spaces are open, if spinous processes are in profile |
| anatomy seen in spot view | L5-S1 |
| angle and CR positioning for spot | 5-8 degrees caudad, CR 1-2'' posterior to ASIS. use C-hand |
| anatomy seen in oblique lumbar views | zygapophyseal joints |
| Scottie dog is composed of | transverse process, pedicle, pars interarticularis, inferior and superior articular processes, and zygapophyseal joint |
| criteria for AP axial SI joints | open joints on both sides- |
| angle for AP axial SI joints | prone- 30-35 caudad supine- 30-35 cephalad |
| Ferguson method | AP axial L5-S1 or scoliosis series |
| ferguson scoli series uses | lifts to correct curvature |
| why do PA instead of AP | PA gives the pt lesser dose to gonads and breast tissue |
| SI joints= Ferguson= | -pelvis -spine |
| PA sacral angle | would be 15 degrees caudad. cephalad for AP |
| right and left bending lumbar spine views are done to see | spinal fusions |
| a n a c q u i r e d b o ny d e f e c t o c c u r r i n g i n t h e p a r s i n t e ra r t i c u l a r i s ( n e c k o n t h e S c o t t i e d o g | spondylolysis |
| osteopetrosis | increased density of typically soft bone |
| RPO/LPO shoes side | closest to the IR |
| RAO/LAO shows side | farthest from the IR |
| in AP oblique L-spine, When the joint is not well seen, and the pedicle is posterior on the vertebral body, patient | rotated too much. |
| In AP oblique L-spine, When the joint is not well seen, and the pedicle is anterior on the vertebral body, patient | not rotated enough. |
