Question 19

With right heel strike, in what directions did the right and left innominate rotate?

Answer 19

With right heel strike, the right innominate rotates posteriorly and the left rotates anteriorly.

Question 20

With right heel strike, in what direction is the anterior and superior surfaces of sacrum rotated, and what direction is the spine rotated?

Answer 20

Anterior surface is rotated to the left and the superior surface is level. The spine is straight but rotated left.

Question 21

With right leg mid-stance (left left lift off), in what direction is the right innominate rotated, the sacrum, and lumbar spine?

Answer 21

Right innominate is rotated anteriorly.

The sacrum is rotated right but SB left and lumbar spine is rotated left but SB right.

Question 22

At left heel strike, explain direction of motion for the left innominate, and right innominate after toe-off.

Answer 22

With left heel strike, left innominate begins anterior rotation. After toe-off, right innominate begins posterior rotation.

Question 23

With left heel strike, in what direction is the anterior surface of sacrum rotated? the spine?

Answer 23

Anterior surface of sacrum is rotated right and spine is also rotated right.

Question 24

During left leg stance, in what direction are the sacrum and lumbar spine rotated and SB?

Answer 24

The sacrum is rotated left and SB right. The lumbar spine is rotated SB left and rotated right.

Question 25

A 26yM soccer player presents with complaints of right side low back pain that at times keeps him from playing. Pain is worse with kicking and cutting right to left. He states it feels as through his pelvis locks up. His structural exam is: Standing flexion test positive on right, seated flexion test is negative; Pubes are level, ASIS is inferior on the right, PSIS is superior on the right. What is the diagnosis?

Answer 25

Anterior innominate rotation

Question 26

Describe what is meant by the form closure.

Answer 26

Form closure describes the stability of the joint from the design of the pelvic anatomy. -Sacrum and ilium has both flat and rough ridges. together they provide highest coefficient of friction and protect against shearing. The position of the bones in the SIJ creates a keystone-like shape, and the sacrum wider superior and narrower inferior shape allows the sacrum to be wedged in between the ilium.

Question 27

Describe what is meant by Force closure.

Answer 27

Describes the other forces acting across the joint to create stability. This is generated by structures with a fibre direction perpendicular to the sacroiliac joint and is adjustable according to the loading situation. Some contributing factors include: muscles, ligaments, and thoracolumbar fascia. Force closure is especially important during activities like walking when unilateral loading of the legs creates shear forces.

Question 28

The form closure mainly functions to _ the pelvis, while the force closure allows for_.

Answer 28

stability | mobility

Question 29

Which ligament restricts nutation?

Answer 29

Sacrotuberous ligament

Question 30

Which ligament restricts nutation and side bending?

Answer 30

Iliolumbar ligament

Question 31

Which ligament restricts counter nutation

Answer 31

Long and dorsal sacroiliac ligament.

Question 32

During anterior innominate rotation, what is the orientation of the ASIS, PSIS, and medial malleolus?

Answer 32

ASIS is inferior PSISI is superior Medial malleolus is inferior (long)

Question 33

During posterior innominate rotation, what is the orientation of the ASIS, PSIS and medial malleolus?

Answer 33

ASIS is superior PSIS is inferior medial malleolus is superior.

Question 34

During superior shear, what is the position of the ASIS, PSIS, and medial malleolus on the affected side?

Answer 34

ASIS and PSIS are superior. | Medial malleolus is also superior and thus short.

Question 35

During inferior shear, what is the position of the ASIS, PSIS, and medial malleolus on the affected side?

Answer 35

ASIS, PSIS and medial malleolus are inferior on the affected side (long)

Question 36

Which muscles induces Anterior tilt? Posterior tilt?

Answer 36

Anterior tilt induced by: Rectus femoris, and erector spinae | Posterior tilt induced by: gluteus maximus, hamstring, and rectus abdominis and external oblique muscles.
