Thoracolumbar Vertebrae Flashcards
Know the slope of the lumbar dorsal spinous processes and the relationship they have to the lumbosacral space.
L3 is tallest/largest, large space between L5-L6, next large space is LS space, can’t feel L1, goes up to L3, then back down
Know the location of the intertransverse joints and their function
Between the transverse processes of L5-L6 and sometimes L4-L5, also b/t L6 and sacrum
Three common variations of the anatomy in the lumbosacral region
- L6 can be sacralized or fused to the sacrum
- Number of intertransverse joints vary
- Occasional rib remnant at L1
Order the nerves come off of the lumbar plexus (6)
- Genitofemoral (L2-L4)
- Femoral (L3-L6)
- Obturator (L4-S1)
- Sciatic (L5-S2)
- Cranial and Caudal Gluteal (L6-S2)
- Pudendal (S2-S4)
How can a lumbar restriction affect the ribs?
Cranial lumbar restriction affects ribs via lumbocostal ligament
How to palpate and adjust a lumbar dorsal
On bale, calcaneal contact on each dorsal spinous process, elbow should be vertically aligned with contact point
How to palpate a DSP right or left.
Wiggle tail, fingers on either side of DSP, should feel DSP move left and right slightly
Know two ways to adjust a DSP left or right.
On bale,
On same side as restriction – contact point is DSP LOC is 10 degree angle, double pisiform
Opposite side of restriction – contact point is mamillary process, LOC is DV, double pisiform
Know the LOC for the cranial thoracics and for the caudal thoracics.
Caudal is straight dorsal ventral, angle slowly changes as you move cranially
Know the restrictions possible in the thoracic vertebrae
