Because it is incomplete inferiorly- acetabulum notch

1

What is the acetabular labrum and what does it do?

It is a fibrocartilaginous rim attached to the margin of the acetabulum.
It increases articular contact area by 10%, meaning that over 50% of the femur head sits in the acetabulum.

2

What ligament strengthens the inferior portion of the acetabulum?

Transverse acetabular ligament

3

Why are ligaments required around the joint?

To increase stability and strengthen the joint capsule.

4

What does the ligament of the head of the femur do?

Provides a small arterial supply (obturator artery) to the head of the femur.

5

What are the 3 extra capsular ligaments?

-iliofemoral
-ischiofemoral
-pubifemoral

6

Which two ligaments are found anteriorly?

Iliofemoral and pubifemoral

7

Which ligament is found posteriorly?

Ischiofemoral

8

What does the iliofemoral ligament do?

Prevents hyper extension of the hip joint

9

What does the pubifemoral ligament do?

Prevents excessive abduction and extension

10

What does the ischiofemoral ligament do?

Prevents excessive extension of the femur at the hip joint.

11

Which muscles flex the hip? (3)

Sartorius, iliopsoas, rectus femoris

12

Which muscles extend the hip? (4)

Gluteus maximus, biceps femoris long head, semi membranous, semitendinous

13

Which muscles laterally rotate the hip? (5)

Periformis, superior and inferior gemellus, obturator internus, quads

14

Which muscles abduct the hip?(3)

Gluteus minimis and medius, tensor fasciae latae

15

Which muscles adduct the hip? (6)

Pectineus, gracilis, obturator externus, adductor brevis, longus and Magnus

16

What are the 3 bursae of the hip?

Iliopsoas
