1

What is the larger, medial bone in the leg?

Tibia.

2

What shape is a cross-section of the tibia?

Triangular.
-medial, lateral and posterior surfaces

3

Where is the soleal line and what attaches to it?

On the posterior surface of the proximal tibia.
-soleus muscle

4

Where is the tibial tuberosity and what attaches to it?

On the anterior surface of the proximal tibia.
-patellar ligament

5

What is acute osteomyelitis?

Inflammation of longer bones due to new infection in the bone.
-predominantly in children

6

What is a common site for acute osteomyelitis?

Proximal end of the tibial shaft.

7

Why is the tibia the commonest long bone to be fractured?

-Superficial and unprotected ant/med
-Particularly slender in lower 1/3.

8

What is a compound injury?

Break in continuity of bone that pierces skin.
-dirt/bacteria can enter

9

What is the smaller, lateral bone in the leg?

Fibula.

10

What does the fibula articulate with proximally?

Lateral condyle of tibia.
-does not form knee joint

11

What does the fibula articulate with distally?

Anchored to tibia by fibrous joint.

12

What is the interosseous membrane in the leg?

Fibrous joint that unites the tibia and fibula.

13

What is the function of the interosseous membrane in the leg? (2)

-Separates muscles into anterior and posterior compartment
-Site of attachment for muscles

14

How many foramina are there in the interosseous membrane?

Two.

15

What is the function of the 2 foramina in the interosseous membrane?

SUPERIOR - anterior tibial vessels pass through to anterior leg
INFERIOR - anterior fibular vessels (perforation branches) pass through

16

What is another name for fibular?

Peroneal.

17

How many compartments are there in the leg?

Three.
-anterior/posterior/lateral

18

What divides the leg into 3 compartments?

-Interosseous membrane
-2 intermuscular septae
-Attachment of deep fascia to periosteum

19

What are the muscles of the anterior compartment of the leg? (4)

-Tibialis anterior (most med)
-Extensor hallucis longus
-Extensor digitorum longus
-Fibularis tertius

20

Which muscle is not present in everyone?

Fibularis tertius.
-considered part of extensor digitorum longus

21

Which muscle is lateral to tibialis anterior and partially covered by it?

Extensor hallucis longus.

22

What is the nerve supply to the anterior compartment of the leg?

Deep fibular nerve.
-branch of common fibular

23

What is the blood supply to the anterior compartment of the leg?

Anterior tibial artery.

24

How many extensor retinaculum are there on the leg?

Two.
-superior and inferior
-both on anterior ankle

25

What is the function of the retinaculum?

Holds tendons in place and stabilises them.

26

What are the main functions of the anterior compartment of the leg? (3)

-Dorsiflex foot
-Extend toe
-Invert foot

27

Where are the origins and insertions of extrinsic muscles of the foot?

Origins - leg
Insertions - foot

28

Where are the origins and insertions of intrinsic muscles of the foot?

Origins - foot
Insertions - foot

29

What are the extrinsic extensors of the foot? (2)

-Extensor hallucis longus
-Extensor digitorum longus

30

What is the function of fibularis tertius?

-Dorsiflexion
-Eversion of the foot (unlike other ant compartment muscles)
