Innominates

Question 1

What 3 bones does the innominate consist of?

Answer 1

ilium, pubis, ischium

Question 2

What are the ring of joint?

Answer 2

2 sacroiliac joints
1 pubic symphysis
2 hip joints

Question 3

What are the major anterior bony landmarks?

Answer 3

iliac crest, ASIS, AIIS, pubic symphysis

Question 4

What are the major posterior bony landmarks?

Answer 4

PSIS, PIIS, ischial tuberosity

Question 5

What is the development process of the innominate?

Answer 5

not fused at birth; acetabulum formed from 3 ossification center

Question 6

What are the common ligaments that are painful due to overuse?

Answer 6

iliolumbar, posterior sacroiliac, sacrospinous, sacrotuberous

Question 7

Which muscles inset superior?

Answer 7

quadratus lumborum, rectus abdominus

Question 8

Which are hip flexor muscles?

Answer 8

iliopsoas, rectus femoris

Question 9

Which are hip extensor muscles?

Answer 9

glut max, hamstrings

Question 10

Which muscles are abductors?

Answer 10

glut med, glut min, TFL

Question 11

What muscle is a hip external rotator?

Answer 11

piriformis

Question 12

How does the pelvis relate to lymphatics, GI/GU?

Answer 12

lymphatic trunks from lower extremity

pelvic floor/diaphragm is important in regulation

Question 13

How does pelvis have biomechanical influence?

Answer 13

foundation of trunk
maintain stability during movement
transmits force during gait

Question 14

What does each finger represent in air hands?

Answer 14

thumbs = PSIS
pointers = ASIS
pinkies = pubic tubercles

Question 15

Motion of anterior rotation

Answer 15

ASIS- inferior compared to contralateral
PSIS- superior
Ischial tuberosity- superior

Question 16

Motion of posterior rotation

Answer 16

ASIS- superior
PSIS- inferior
Ischial tuberosity- inferior

Question 17

Innominate rotation associated with right heel strike

Answer 17

right let swings forward
right innominate rotates posteriorly
right heel strikes the ground

Question 18

Innominate rotation associated with right toe off

Answer 18

weight is loaded into right foot
trunk moves forward
right innominate rotates anteriorly

Question 19

Primary motion of superior shear

Answer 19

ASIS- superior
PSIS- superior
Ischial tuberosity- superior

Question 20

Primary movement of pubic shear

Answer 20

Pubic tubercle- superior or inferior

Question 21

Primary motion of flare

Answer 21

can tip in (in flare) or tip out (out flare)

ASIS more medial or lateral compared to contralateral

Question 22

What is the 1st step in assessment of innominates?

Answer 22

screen the innominates for SD then further diagnose

Question 23

What is the 2nd step?

Answer 23

lateralization tests (compression or standing flexion)

Question 24

What muscles should you check for in TART screening?

Answer 24

QL (sup shear)
Erector spinae (sup shear)
SI joint (sacral SD)
Piriformis (sacral SD)
Hamstrings (post rotation)
Quads (anterior rotation)
Adductors (pub shear)

Question 25

What is the ASIS Compression test?

Answer 25

motion challenge of posterior medial compression of ASIS to asses the SI joint

Question 26

What is the standing flexion test?

Answer 26

motion challenge = stability during flexion, assessing ability of SI joint to stabilize
PSIS will move more superior on dysfunctional side (carried by musculature)

Question 27

What is the 3rd step?

Answer 27

Palpate landmarks

Question 28

What landmarks do you compare?

Answer 28

iliac crest
ASIS
PSIS
pubic tubercles
ischial tuberosity
medial malleoli

Question 29

What is the 4th step?

Answer 29

diagnose somatic dysfunction
