1

Where does the head of the femur articulate with the pelvis?

Acetabulum

2

Which 2 parts come together to form the linea aspera?

Pectineal line and gluteal tuberosity

3

Is the linea aspera on the anterior or posterior femur?

Posterior

4

Is the intertrochanteric crest on the anterior or posterior femur?

Posterior

5

Which side of the distal femur is the adductor tubercle on?

Medial side

6

The medial malleolus is formed from which bone?

Tibia

7

The lateral malleolus is formed from which bone?

Fibula

8

Name the proximal tarsals

Talus
Calcaneus

9

Name the intermediate tarsal

Navicular

10

Name the distal tarsals

Cuboid
3 Cuneiforms

11

How many tarsal do we have per foot?

7

12

Where does the greater sciatic foramen run?

Down the lateral aspect of the ilium and round the posterior of the acetabulum

13

What is the Pes Anserinus?

Conjoined tendons of 3 muscles that insert on the anterior, medial, proximal tibia
3 muscles: sartorius, gracilis and semitendinosus

14

What shape is the ligament to the head of the femur?

Triangular

15

What is special about the ligament of the head of the femur?

Contains small arterial blood supply to the head of the femur

16

Which 3 parts of the pelvis come together at the acetabulum?

Ilium
Ischium
Pubis

17

What do we call the part of the acetabulum where it is incomplete inferiorly?

Acetabular notch

18

Which ligament supports the inferior part of the acetabulum?

Transverse acetabular ligament

19

Which 3 ligaments reinforce the joint capsule of the hip?

Iliofemoral
Pubofemoral
Ischiofemoral

20

Describe the iliofemoral ligament

Y shaped
One of the strongest ligaments in the body
Ilium to intertrochanteric line
Prevents hyperextension
Reinforces anterior and superior portion

21

Describe the pubofemoral ligament

Attaches to pubic bone and femur
Protects anteriorly
Prevents over abduction

22

Describe the ischiofemoral ligament

Posterior
Weakest of the 3
Ischium to the femur
Limits extension

23

Of the quadriceps, which is the only one that can exert an affect on the hip?

Rectus femoris

24

Name the main hip flexors

Iliopsoas
Rectus femoris
Sartorius

25

Name the adductors of the hip

Adductor magnus
Adductor longus
Adductor brevis
Pectineus
Gracilis
Obturator externus

26

Which nerves supply the hip joint and at which faces?

Femoral nerve = anterior
Nerve to quadratus femoris = posterior
Obturator nerve = inferior
Gluteal superior nerve = superior

27

What is the major source of blood supply to the hip?

Medial circumflex femoral artery
Lateral circumflex femoral artery

28

What is the minor blood supply to the hip?

Obturator artery via ligament of head of femur

29

Which type of femoral fractures are more likely to result in avascular necrosis?

Intra capsular

30

Define ankylosis

Stiffness of a joint due to abnormal adhesion
