1

What are innominates?

Hip bones

2

What are the important bony landmarks?

Iliac crests
ASIS
Pubic tubercles
Medial Malleoli
PSIS

3

What are the pelvic ligaments that stabilize the pelvis?

Iliolumbar
Sacroiliac - anterior and posterior
Sacrospinous
Sacrotuberous

4

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

5

Form closure

SI joint stabilized by gravity and shape of joint (sacrum and innominate bones)

6

Force closure

SI joint stabilized by joint compression by muscles, ligaments, thoracolumbar fascia (all non-bone things)

7

Form closure and Force closure are important for?

Stable foundation for trunk and to transmit force with gait

8

SI joint pain is _____ % of chronic low back pain

15-25%

9

What are the 3 innominate motions?

Innominate rotation
Innominate and pubic shear
Innominate flare

10

When testing for innominate dysfunction what are you comparing bony landmarks to?

The contralateral side!

11

If an innominate rotates anterior, describe the locations of the ASIS and PSIS

ASIS = inferior
PSIS = superior

12

If an innominate rotates posterior, describe the locations of the ASIS and PSIS

ASIS = superior
PSIS = inferior

13

At what stage in walking is the innominate rotated posteriorly?

Heel strike

14

At what stage in walking is the innominate rotated anteriorly?

Toe off

15

What motions of the innominates are generally pathologic and cause pain?

Shear and flare

16

Innominate shear

ENTIRE innominate is superior or inferior

17

Pubic shear

ONLY PUBIC TUBERCLES are superior or inferior

18

Innominate flare

ASIS is more medial or lateral compared to opposite side - measure relative to umbilicus

19

Innominate inflare

ASIS more medial

20

Innominate outflare

ASIS more lateral

21

What are the 3 sacral motions?

Flexion (nutation)
Extension
Oblique axis rotation

22

The sacrum flexes and extends around what axis?

Transverse axis

23

Sacral nutation

Flexion

24

When the sacrum flexes around the transverse axis, what tips forward?

Sacral base

25

The sacrum rotates around what axis?

Oblique

26

What is an oblique axis?

Vertical axis slightly tilted

27

How is the sacral oblique axis named?

For which sacral base (R/L top corner) it passes through

28

Ex. Left oblique axis with right rotation. What is the sacral movement?

Top right sacral base rotates posteriorly

29

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

30

How do you screen innominate for somatic dysfunction (step 1)?

Have them stand, and you sit behind them and assess for posterior spine/innominates TART - find one side that is worse
