Innominates Flashcards
what are the positions of the ASIS, PSIS, and the ischial tuberosity when the innominate rotates anteriorly?
the ASIS is inferior, the PSIS is superior and the ischial tuberosity is superior
what are the positions of the ASIS, PSIS, and the ischial tuberosity when the innominate rotates posteriorly?
ASIS is superior, PSIS is inferior, ischial tuberosity is inferior
what happens to the right innominate when the right leg heel strike (swings forward)?
right innominate rotates posteriorly
what happens to the right innominate when the right foot toe off aka weight is loaded into the right foot?
the right innominate rotates anteriorly
what is an innominate shear?
the entire innominate is moved superior or inferior
what is a pubic shear?
only the pubic tubercle moves superior or inferior
what muscles are associated with an innominate shear?
the quadratus lumborum and the erector spinae muscles
what muscles are associated with a pubic shear?
adductor contraction
what is flaring of the innominates?
the innominate can either tip in (inflare) or out (outflare)
how do you measure a flare?
you look to see if the ASIS is more medial or lateral compared to the contralateral side
what happens to the sacrum base during sacral flexion?
the sacrum base tips anteriorly
what happens to the inferior lateral angles during sacral flexing?
the inferior lateral angles tip posteriorly
what axis is the flexion/extension of the sacrum around?
the transverse axis
what are the two lateralization tests?
ASIS compression test and the standing flexion test
how do you determine if there is a dysfunctional side on a standing flexion lateralization test?
the PSIS will move more superiorly on the dysfunctional side
What are the findings of a right anterior rotated innominate?
iliac crest: even ASIS: inferior PSIS: superior Pubic tubercles: Even Medial Malleoli: inferior
What are the findings of a right posterior rotated innominate?
iliac crest: even ASIS: superior PSIS: inferior pubic tubercles: even Medial Malleoli: superior
what are the findings of a right superior innominate shear?
everything on the right is superior
what are the findings of a right inferior innominate shear?
everything on the right is inferior
what are the findings of a right innominate inflare?
the ASIS is more medial on the right
what are the findings of a left innominate outflare?
the ASIS is more lateral on the left
what are the findings of a right superior pubic shear?
the pubic tubercle is more superior
what are the findings of a right inferior pubic shear?
the pubic tubercle is more inferior
