Exam I Flashcards
What are the three bones of the pelvis?
illium
ischium
pubus
what are the landmarks/bones for the ischium
PIIS, ischial tuberosities and ischial rami
what are the landmarks/bones of ilium
iliac crest (ASIS to PSIS)
what are the landmarks/bones of the pubus
AIIS, pubic rami, tubercles, symphysis
what are the two ligaments of the sacrum
sacrotuberous and sacrospinal
muscles that make up the pelvic diaphragm?
levator ani, coccygeous
when skull is in flexion the sacrum
extends
what is the dural connection
occiput/C1/C2 to S2
where is repiratory cranial postion on the sacrum
S2, superior transverse axis
the innominates follow the __________
sphenoid/temporal
what is the motion of the pelvis about the SI joint
shearing/gliding
what is the motion of the pelvis about the pubic symphysis
shearing/gliding
what is the pelvis is adducuted or abducted what is this called?
inflare or outflare
what is the middle transverse axis of the sacrum represent
sacral postural flexion/extension
what is the inferior transverse axis of the sacrum represent
innominate rotation, dynamic/walking
ASIS superior PSIS superior standing flexion positive ipsilaterally (usually) pubic rami may be involved iliac crest superior ischial tuberosity superior
superior pelvic shear
Standing flexion test positive ipsilaterally Usually
Ipsilateral inferior ASIS
Ipsilateral inferior PSIS
Pubic rami may be involved
inferior ipsilaterally
Iliac Crest inferior ipsilaterally
Ischial tuberosity inferior ipsilaterally
inferior pelvic shear
what is the significance of superior pelvic shear with hip replacement hisoty
cannot internally rotate then as it risks dislocation of the hip so external rotation will alllow some packing of the hip joint to allow for traction then pull of the lower extremity to translate to the pelvis
abducted pubic symphysis common in what population
8-9 month pregnant people
what happens to pelvis with inflare
superior
what happens to pelvis with outflare
inferior
Distance of ipsilateral ASIS to midline decreased
Standing flexion test positive ipsilaterally
Superior ASIS ipsilaterally
Equal to superior PSIS ipsilaterally
Pubic rami equal
Iliac Crest superior ipsilaterally
Ischial tuberosity equal
inflare
Distance of ipsilateral ASIS to midline increased
Standing flexion test positive ipsilaterally
Inferior ASIS ipsilaterally
Equal to superior PSIS ipsilaterally
Pubic rami equal
Iliac Crest inferior ipsilaterally
Ischial tuberosity equal
outflare
what are the leading cause of fatal and nonfatal injuries in older adults
falls
what are common fall related risk factors
vitamin D deficiency
multiple prescritpion meds
environmental hazards and impaired strength and balance
