left lower quadrant, low pack pain/ pelvic pain; can refer to hip/ thigh with abscess formative
Affects ages of 40-60+years
Pain is usually bilateral
Occurs in calf (foot, thigh, hip, or buttocks)
NO burning or dysethesia
Pain consistent in all spinal positions
Pain is brought on by physical exertion, relieved promptly by rest (1-5 min)
Pain is increased by walking uphill
Decreased or absent pulses in LE
Color and skin changes in feet; cold, numb, dry, or scaly skin; and poor nail and hair growth
intermittent claudication (vascular claudication of LS plexus)
A disorder of the elderly
Pain is usually bilateral and occurs in back, buttocks, thighs, calves, and feet
Burning and numbness present in LE
Pain is decreased in spinal flexion and increased in spinal extension and with walking
Pain is decreased by recumbency (walking uphill)
Pain is relieved with prolonged rest (may persist hours after resting)
Normal pulses
spinal stenosis
3 parts to a lumbar vert
body
pedicle
post elements
the function of the body of the vertebrate
WB - compression
3 main parts of the post elements
lamina
pars
mamillary process
what is the lamina
bony protective covering over neural contents
significance of mammillary process

nucleus of the IVD resists what force
comprssion
nucleus is type __ collagen
2
anulus fibrosis is type ___ collagen
1
anulus resists what type of force
tensile forces
function of IVD
transmit force btwn bodies
aid in proprioception
with distraction, what fibers of AF are effected
ALL with distraction
with shearing forces, what fibers of AF are effected
only those in the line of force
optimal stimulus for regeneration of AF is
rotation
optimal stimulus for regeneration of NP is
compression/decompression
where the end plates don’t cover the AF, but rather the AF fibers insert in to the bone of the body of the vertebrae is called
sharpey fibers
the principal WB of lumbar spine is the ___joints
interbody
function of facet joints (or zygoapophaseal joints)
locking to prevent anterior translation
optimal stimulus to regenerate facet joints
compress/decompress
PLL and LF resists lumbar

area on body where there is no movement of neural tissue as other tissues move
tension point
during a side bend, the ___ side of the joint closes and the ___ side opens
ipsi closes
contra opens
facets of L1-L4 are vertically oriented, so this facilitates __ and __
flexion and ext
what motion is limited for L1-L4
rotation and side bending
facets of L5 and S1 resist what motions
flexion and ext
in neutral spine, what motions are coupled
SB and Rot are opposite
in extended spine, what motions are coupled
SB and Rot are opp
in flexed spine what motions are coupled
SB and rot are SAME
quadrant movement is
combined (not natural)
so in ext combined/quadrand movement is
SB and rot are same
IDD means
internal disc disruption
tearing of AF through the end plate can lead to extrusion. before this occurs, the pt often has
schmorls nodes at that location
primary MOI of a lumbar disc injury would be what motions
repetitive lifting or bending with rotation in a neutral spine
avulsion fxs are due to
lack of anchoring of AF fibers
if disc materials migrate out of of the annular fibers it is considered
EDD
type of disc disorder where the fissures occur inside out (IDD)
transverse radial
which will have pos tension signs, IDD or EDD

saddle and medial ankle
hallux radicular area is which lumbar vert again
L4 hallux
order of severity of HNP
TLE (protrusion, prolapse, extrusion)
2 types of prolapse
central - PLL just irritated
PPL (primary, post lat) - goes outside of PLL
extrusion is so severe bc
it ruptures PLL
“sick disc” unstable
extrusion
if pt c/o sensory sx first think
primary dorsal root with secondary disc
if pt c/o motor sx first think
primary disc 2ndary ventral root
type of stenosis where there is loss of disc ht
the spinal canal encroaches around the nerve
lateral
pt will present with px where for DDD/DJD
B LBP

describe location of px with prolapse
prolapse- px in leg and lumbar and in complete dermatome pattern
describe px with extrusion

may take over entire limb and be poly sectional
with a PPL disc issue, the px is usually where
px is not in lumbar, but rather it is all leg
protrusion or prolapse has fast onset
prolapse
will neurodynamic testing (SLR or slump) be pos for disc with nerve root involvement
yes
what type of disc issues would yield pos neuro exam findings
prob not protrusion or central

what test is always pos for facet
quadrant
sharp px with sudden movment reports of weak or giving way feeling px increases during the day no neuro sx unilateral px ab muscle activation decreases sx
instability
protrusion vs prolapse
protrusion - Displacement of nuclear material beyond inner annulus causing bulge in outer annulus without escape of nuclear material (outer annulus is intact).
prolapse - Displacement of nuclear material beyond inner annulus WITH ESCAPE of nuclear material

when a pt shifts to a side, you name the shift by
direction of the shoulders
differences btwn stenosis and vascular claudication
stenosis- px decreases uphill
claudication -px increases uphill (px comes on with physical exertion)
stenosis- burning
