Lumbar Spine Flashcards
l1-l5 is progressively blank shaped because blank body is larger than blank
wedge, anterior, posterior
spinous processes of lumbar are blank from lateral view
broad
lumbar spinous processes are blank from superior view
thin
tp of lumbar corresepond to blank level of sp
same level
superior facet is blank and faces blank and blank
concave, medially, slightly posterior
inferior facet is blank and faces blank and blank
convex, laterally, slightly anterior
facets of lumbar lie in blank plane progressively toward l5 at blank
sagittal, 90%
l5 has blank to sacrum in this
fused, sacralization
degenerative blank disease usually comes before blank
disc, joint
ligament that narrows to non existence in the lumbar spine
pll
supraspinous connects blank to blank
sp tip to tip
5 bands extending from l4/l5 tp’s to iliac crests just above the psis
iliolumbar ligaments
iliolumbar ligaments are very blank and prevent blank displacement of l4 and l5
strong, anterior
superficial to deep ligaments of spine
supraspinous, interspinous, ligamentum flavum
ligamentum flavum is high in blank content which makes it yellow
elastin
ligamentum flavum can blank which causes stenosing
hypertrophy
fracture of vertebral end plate into body above or below
schmorl’s node
schmorls node can alter blank which can lead to blank
circulation, necrosis
passive stabilizer that has 3 layers (ant,mid,post) and attaches to sp and tp and other tissues
thoracolumbar fascia
anterior and middle thoracolumbar fascia layers are derivatives of the blank and attach to blank
quadratus lumborum, tp’s
posterior layer of thoracolumbar fascia fuses with the transverse abdominis, gluteus maximus, and lat dorsi, then attaches to the blank
sp’s
vertical fibers of thor fascia attaches to blank and blank
glute max, sp
thor fascia horizontal fibers attach to blank, and blank
sp, transverse abdominis, abdominal obliques
erector spinae are blank muscles
divergent, central to lateral (v shaped)
erector spinae are blank muscles which are movers
spurt
spurt muscles have insertions blank axis of rotation
close to
multifidus and rotatores are blank muscles because inserition is lateral to central
convergent
multifidus and rotatores are blank because they are short going from tp to sp and do stabilization mainly
shunt
action to create trunk flexion or posterior pelvic rotation
rectus abdominis
standing trunk flexion has blank involvement of rectus abs
no
