Hip Ligaments of the Pelvis and Capsule

Question 1

Sacrospinous Ligament (of the pelvis)

Answer 1

ischial spine (anterior)
-sacrum lateral border
-coccyx
turns greater sciatic notch to foramen

Question 2

Sacrotuberous Ligament (of the pelvis)

Answer 2

ischial tuberosity (posterior)
- lateral sacrum
- coccyx
- PSIS, PIIS
turns lesser sciatic notch into foramen

Question 3

Sacroiliac Ligament (of the pelvis)

Answer 3

ilium
- sacrum
supports sacroiliac joint

Question 4

Iliolumbar Ligament (of the pelvis)

Answer 4

transverse process of L5

• iliac crest
• (sacroiliac ligament)

Question 5

Inguinal Ligament (of the pelvis)

Answer 5

ASIS
- pubic tubercle
most common location for hernia’s

Question 6

Iliofemoral Ligament (capsule)

Answer 6

“Y” lig - thickest, strongest
AIIS + acetabalum
- greater trochanter of femur

Question 7

Iliofemoral USE

Answer 7

• stabilizes capsule anteriorly

- prevents hyperextension, excessive lateral rotation

Question 8

Pubofemoral Ligament (capsule)

Answer 8

pubis

- neck of femur

Question 9

Pubofemoral USE

Answer 9

• stabilizes capsule inferiorly

- prevents excessive hip extension, lateral rotation, abduction

Question 10

Ischiofemoral Ligament

Answer 10

posterior acetabalum

• anterior neck of femur
• greater trochanter

Question 11

Ischiofemoral USE

Answer 11

• prevents excessive hip extension, medial rotation

- stabilizes capsule superiorly, posteriorly
