Pelvis practice quiz Flashcards
what conditions can easily be confused for piriformis syndrome b/c it has similar symptoms
lumbar nerve root compression
what is a major factor likely to contribute to SI joint dysfunction
leg length discrepancy
a lateral pelvic tilt is most likely caused by
hypertonic right QL
compression of the superior gluteal nerve in piriformis syndrome is most likely to produce weakness is which muscle
glute min
what muscle has fibrous connections w the sacrotuberous ligament, and could therefore be implicated in SI joint dysfunction
hamstrings
tightness in which mm’s would produce anterior pelvic tilt
spinal erectors
QL
TFL
iliopsoas
rec fem
a structurally longer right leg would most likely produce what postural distortion
left lateral pelvic tilt
test for integrity of posterior SI ligaments
prone gapping test (HIbbs)
posterior pelvic tilt - mms that are short and tight
hamstrings
a structurally longer right leg would be most likely to produce which of the following postural distortions
left lateral pelvic tilt
what is likely to increase lumbar lordosis
anterior pelvic tilt
if pt has pronounced anterior pelvic tilt, it would also be likely that this postural problem would lead to
lumbar facet joint dysfunction
lumbar lordosis is decreased the greatest in which of the following postural disorders
posterior pelvic tilt
a key contributing factor to lateral pelvic tilt is
lumbar scoliosis
key contributing factors to sacroiliac joint pain
leg length discrepancy
lateral pelvic tilt
scoliosis
a key challenge to evaluating SI joint dysfunction w physical examination is
identification of joint position or mechanics is not always accurate
if your pt has an iliopsoas strain, the evaluation procedure most likely to reproduce that pain sensation would be
resisted hip flexion
which SI ligaments limits anterior pelvic rotation
long posterior SI ligament
one of the strongest ligaments in the body and is major connection between the sacrum and ilium
interosseous
form closure is also known as
close packed position of the joint
nutation = what pelvic tilt
posterior sacral tilt
during counternutation, the ilium rotates in what direction on the sacrum
anteriorly
base of sacrum moves backwards
if the ASIS and PSIS on one side is higher than the other ASIS and PSIS , it is called what
upslip
when a pt goes from supine to sitting, what does the innominate bones and pelvic girdle do
as a whole, they rotate anteriorly as a unit on the femoral head bilaterally
with pelvic degeneration what structure is usually affected first
iliac surface
non inflammatory bone formation on the iliac side of the sacroiliac joint is called
osteitis condensans ilii
O and I of piriformis
anterior surface of sacrum, S1-S4 and runs to the medial superior aspect of the greater trochanter
actions of piriformis
externally rotate femur
horizontally abduct thigh when hip is flexed to 90
internally rotates femur w hip fully flexed
restrain rapid internal rotation of hip
