Innominates

Question 1

Anterior/Posterior rotation of the innominate occurs about what axis of the sacrum?

Answer 1

The transverse axis of the sacrum

Question 2

Describe physiologic motion of the innominates:

Answer 2

Anterior rotation happens with extension of the hip

Posterior rotation happens with flexion of the hip

(this is simple)

Question 3

Symptoms of anterior/posterior rotation?

Answer 3

xx

Question 4

Innominate flare (lateral positional change):

Answer 4

ASIS medial or lateral compared to its usual position (May be thought of as rotation of an innominate along a vertical axis)

Question 5

Inflaring happens with:

Answer 5

W/ extension of the hip, or anterior innominate rotation

Question 6

Outflaring happens with:

Answer 6

W/ flexion of the hip, or posterior innominate rotation

Question 7

What is shear?

Answer 7

Shear is a non-physiologic motion (the body is not meant to move that way…painful –> the ligaments cannot compensate)

Question 8

Standing flexion tests give you…

Answer 8

Laterality with the innominates
