1

Which 3 bones make up the pelvic girdle?

-L & R hip bones
-Sacrum

2

Which 3 joints does the pelvic girdle contain?

-2 sacroiliac joints
-Pubic symphysis

3

Which bony features does the pelvic girdle connect?

The vertebral column to the femurs.

4

What is the function of the pelvis?

-stability, locomotion, protection

5

How is the pelvis positioned in the body?

Tilted forward slightly

6

What is another name for the hip bone?

Innominate bone

7

Which 3 bones fuse to form the innominate (hip) bone?

-Ilium
-Ischium
-Pubic

8

What is the area called where the 3 parts (ilium, ischium, pubis) of the pelvis fuse?

The acetabulum.

9

What is the acetabulum?

The ‘socket’ of the innominate bone that articulates with the femoral head >> hip joint.

10

What type of joint is the hip joint?

Ball and socket synovial joint.

11

What structures are involved in the hip joint?

-Head of femur
-Acetabulum (of innominate bone)

12

What structures provide stability in the hip joint? (3)

-Acetabulum
-Fibrous capsule
-Ligaments

13

What shape is the articular surface of the acetabulum?

Crescent-shaped ('lunate').

14

Where is the acetabulum deficient and what does this form?

Inferiorly >> acetabular notch.

15

What is the acetabular notch bridged by?

Transverse acetabular ligament.

16

What is the acetabular labrum?

Rim of cartilage than deepens the articular surface.

17

What is the proximal attachment of the fibrous capsule of the hip joint?

Rim of acetabulum.

18

What is the distal attachment of the fibrous capsule of the hip joint?

Femoral neck
- intertrochanteric line & greater trochanter

19

What are the main 3 ligaments that strengthen the hip joint?

-Iliofemoral
-Pubofemoral
-Ischiofemoral

20

What do these ligaments attach to distally?

The femur.

21

Which is the strongest ligament at the hip joint?

Iliofemoral ligament.

22

Which is the weakest ligament at the hip joint?

Ischiofemoral ligament.

23

Where does the iliofemoral ligament cover the hip joint?

Superiorly & anteriorly.

24

What is the function of the iliofemoral ligament?

Prevents hyperextension when standing.

25

Where does the pubofemoral ligament cover the hip joint?

Inferiorly & anteriorly.

26

What is the function of the pubofemoral ligament?

Prevents excessive abduction.

27

Where does the ischiofemoral ligament cover the hip joint?

Posteriorly.

28

What causes a pubic rami fracture?

Force from lateral direction.

29

How are pubic rami fractures treated?

Conservatively (i.e. pain relief).

30

What causes an ‘open book’ pelvic fracture?

Straight on force.
-e.g. motorbike crash
