Flashcards in 03 Foot 1 Deck (53):
1

What is the foot divided into

- forefoot
- midfoot
- hindfoot

2

midline of the foot

second metatarsal

3

forefoot consists of

- metatarsals
- phalanges
- metatarsalphalangeal joint

4

The second metatarsal communicates in a direct line with

middle cuneiform

5

attachments on lateral side

everters

6

attachments on medial side

inverters

7

attachments on the anterior surface

dorsiflexors

8

attachments on posterior surface

plantarflexors

9

Why is the dome of the talus the most susceptible site of OCD?

- compression injuries
- lateral ankle sprain

10

joints of the foot

- subtalar
- midtarsal
- tarsometatarsal
- metatarsophalangeal
- interphalangeal

11

subtalar joint between the

- talus
- calcaneus

12

Inversion and eversion occur at this joint

subtalar

13

Which ligaments support the subtalar joint?

- plantar calcaneonavicular (spring)
- bifurcate ligament

14

What do the tibiocalcaneal and tibionavicular ligaments of the deltoid do?

cross and stabilize the subtalar joint

15

What does the tibionavicular ligament do?

crosses and supports the transverse tarsal joint

16

What does the calcaneofibular ligament do?

the only one of the lateral collateral ligaments that supports the subtalar joint

17

How many articular surfaces between the calcaneus and talus?

2 or 3
(anterior and medial may be joined)
posterior

18

area between the articular surfaces of the talus and calcaneus are filled by:

- interosseous talocalcaneal ligament (medially)
- cervical ligament (laterally)

19

Where is the cervical ligament (landmark)

in the sinus tarsi

20

common MOI for a Lis Franc injury

- getting the foot stepped on or run over

21

ligaments of the midtarsal joint

- calcaneocuboid
- talonavicular

22

What movements occur at the metatarsophalangeal joints?

- flexion/extension
- some adduction/abduction

23

What movements occur at the interphalangeal joints?

flexion/extension

24

anterior tibial artery

- becomes the dorsalis pedis after it goes through the extensor retinacula

25

What does the deep fibular n. innervate?

intrinsic muscles on the dorsum of the foot

26

tibial n. (plantar)
division

divides into medial and lateral plantar nerves inferior to the medial malleolus

27

tibial n. (plantar)
What does it innervate?

- intrinsic muscles of the foot
- cutaneous innervation to the skin

28

posterior tibial artery division

- divides into medial and lateral plantar branches to supply the sole of the foot

29

location of the tarsal tunnel

- beneath the flexor retinaculum
- posterior to the medial malleolus

30

The tarsal tunnel is the rout between the leg and foot for:

- tendons of toe flexors
- foot invertors
- tibial n.
- posterior tibial artery

31

hallux valgus

- common condition requiring foot surgery
- displacement of flexor and extensor tendons
- displacement of first MTP joint

32

dermatomes: inguinal ligament

L1

33

dermatomes: great toe

L4

34

dermatomes: dorsum of small toe

S1

35

dermatomes: anal area

S4

36

dermatomes: medial thigh

L3

37

dermatomes: posterior thigh

S2

38

dermatomes: dorsum of middle toe

L5

39

dermatomes: lateral thigh

L2

40

dermatomes: ischial area

S3

41

cutaneous nerves: medial thigh

obturator n.

42

cutaneous nerves: posterior thigh

tibial part of sciatic n.

43

cutaneous nerves: anterior thigh

femoral n.

44

Where is the sural nerve located?

in superficial fascia between the gastrocs heads

45

The sural nerve is a branch of the:

tibial and common fibular n.

46

Sural n. supplies

- posterior surface of leg
- lateral margin of foot

47

provides cutaneous supply to distal lateral leg and dorsum of foot

superficial fibular n.

48

cutaneous nerves: lateral margin of foot

sural n.

49

cutaneous nerves: over medial and lateral distal sole

medial and lateral plantar n.

50

cutaneous nerves: heel

tibial n.

51

cutaneous nerves: medial malleolus

saphenous n.

52

cutaneous nerves: dorsum of foot

superficial fibular n.

53

cutaneous nerves: between first and second toe

deep fibular n.
