Flashcards in Innominates Deck (43)
What are innominates?
What are the important bony landmarks?
What are the pelvic ligaments that stabilize the pelvis?
Sacroiliac - anterior and posterior
What does muscle tension do for the pelvis and what can it lead to?
Stabilizes pelvis but can also lead to pain and somatic dysfunction
SI joint stabilized by gravity and shape of joint (sacrum and innominate bones)
SI joint stabilized by joint compression by muscles, ligaments, thoracolumbar fascia (all non-bone things)
Form closure and Force closure are important for?
Stable foundation for trunk and to transmit force with gait
SI joint pain is _____ % of chronic low back pain
What are the 3 innominate motions?
Innominate and pubic shear
When testing for innominate dysfunction what are you comparing bony landmarks to?
The contralateral side!
If an innominate rotates anterior, describe the locations of the ASIS and PSIS
ASIS = inferior
PSIS = superior
If an innominate rotates posterior, describe the locations of the ASIS and PSIS
ASIS = superior
PSIS = inferior
At what stage in walking is the innominate rotated posteriorly?
At what stage in walking is the innominate rotated anteriorly?
What motions of the innominates are generally pathologic and cause pain?
Shear and flare
ENTIRE innominate is superior or inferior
ONLY PUBIC TUBERCLES are superior or inferior
ASIS is more medial or lateral compared to opposite side - measure relative to umbilicus
ASIS more medial
ASIS more lateral
What are the 3 sacral motions?
Oblique axis rotation
The sacrum flexes and extends around what axis?
When the sacrum flexes around the transverse axis, what tips forward?
The sacrum rotates around what axis?
What is an oblique axis?
Vertical axis slightly tilted
How is the sacral oblique axis named?
For which sacral base (R/L top corner) it passes through
Ex. Left oblique axis with right rotation. What is the sacral movement?
Top right sacral base rotates posteriorly
4 steps to assessing innominates for somatic dysfunction
1. Screen innominates for somatic dysfunction (TART)
2. Lateralization tests
3. Palpate bony landmarks
4. Diagnose innominate somatic dysfunction
