1

When does the distance between the PSIS(s) change in relation to the IN/EX ilium?

An IN will be closer to the center of sacrum, which makes the EX farther from the center of sacrum

2

When the ilia misalign, what other structure is effected (mainly)?

Pubic symphysis

3

When misaligned the pubic symphysis rotates to which side?

The IN side

4

Do subscript measurements give absolute or relative values?

Relative values

5

What is the alternate method of determining IN and EX?

Measure width of the ilia from the most medial part to the most lateral part of the ilia; wider one is IN

6

How do EX/IN alter obturator appearance?

EX- increases the width of the base
IN- decreases width of the base

7

How does EX/IN alter lumbar curve? Femur head level?

EX- hyperlordosis (increases curve), lowers femur head
IN- hypolordosis (decreases curve), raises femur head

8

Describe edema for EX and IN

EX- posterior aspect of joint (can be palpated)
IN- anterior aspect of joint (can't be palpated but often associated with pain)

9

Describe foot flare of EX/IN

EX- toe in
IN- toe out

10

With an IN ilium describe pelvic rotation, feet rotation, head/torso rotation

Pelvis and feet will be rotated to IN side, head and torso rotate to the EX side to compensate

11

What might offset femur head height other than misalignment of the ilia?

An anatomically short leg, knee or ankle injury, previous fractures, etc

12

Describe edema for ASIN, PIEX, ASEX, PIIN

ASIN- anterior superior margin
PIEX- posterior superior margin
ASEX- posterior inferior margin
PIIN- anterior inferior margin

13

What are the perimeters for IN-EX or EX-IN listing?

NO anterior-posterior misalignment and NO lumbar rotation

14

Which one is listed first, IN or EX?

Left one first with a hyphen then the right
