Flashcards in Foot Deck (30):
1

where is the attachment of the superior extensor retinaculum?

anterior border of fib and tib

2

Inferior band of extensor retinaculum is Y-shaped. Where are the three attachments?

medial malleolus
plantar aponeurosis medially
superolateral calcaneus laterally

3

Which muscles does the fibular retinaculum hold down

Fibularis longus and brevis

4

Which fibular retinaculum blends with the extensor retinaculum?

the inferior band, blending with the inferior extensor retinaculum

5

Which pneumonic is used for the flexor retinaculum?

Tom, Dick and Very Naughty Harry

6

What are the two key ligaments stabilising the arch of the foot?

spring and plantar ligaments

7

What is a leg muscle that helps to maintain the arch of the foot?

fibularis longus

8

What is the name of the intrinsic muscle on the dorsum of the foot?

extensor digitorum brevis

9

What is the course of EDB?

arising laterally from the calcaneus, inserting into the tendons of the longus muscles on digits 1-4

10

What shape is the extensor hood?

triangular, with apex pointing to the tip of the toe

11

Which nerve gives all the motor supply for the dorsum of the foot?

deep fibular nerve

12

What is the sensory supply done by deep fibular nerve at the foot dorsum?

first webspace between the first and second toes

13

Describe the course of the dorsalis pedis artery

travels medially and give an arcuate brach that heads laterally. The main branch continues down the big toe, giving a perforating branch to the plantar surface

14

What muscles can be found immediately deep to the plantar neurosis?

Abductors on either side (halluces and minimi)
Flexor digitorum brevis

15

What are the long muscles lying immediately deep to flexor digitorum brevis

FDL, FHL

16

Which muscle has lumbricals associated?

FDL

17

Where does the FDB insert?

on either side of the base of middle phalanx

18

T/F lumbricals arise on the lateral sides of the FDL

False, they arise on the medial side

19

where does the quadratus plantae muscle insert?

the lateral border of FDL when it is breaking into four tendons

20

What is the action of quadratus plantae?

optimising the function of FDL by straightening the line of FDL

21

What muscles can be found on the 3rd layer of the sole of foot

short flexor for the big and little toe
adductor halluces

22

What muscles can be found on the 4th layer of the sole of foot?

interosseous muscles between toes in the inter-metatarsal spaces

23

Where is the reference plane for toe abduction/adduction?

the second digit

24

What is the function of interosseous muscle?

adduction towards the second toe

25

Which layers can the neurovascular plane be found?

between the first and second layers

26

Which artery can be found in the plantar surface?

posterior tibial artery, splitting into medial and lateral branches

27

Which branch of the posterior tibial artery forms the plantar arch?

lateral branch

28

Which nerve supplies the plantar surface of foot?

tibial nerve, splitting into lateral and medial plantar nerves

29

What does the lateral plantar nerve supply?

lateral 1.5 toes and all intrinsic muscles

30

What does the medial plantar nerve supply?

medial 3.5 toes + minor motor component
