Flashcards in Foot and Ankle Deck (32):
1

what stabilizes the tibiotalar joint

deltoid ligament, anterior talofibular and posterior talofibular and calcaneofibular ligaments

2

where does the deltoid lig attach to

medial malleolus, navicular tuberosity, sustentaculum tali of calcaneus and the talus

3

where deos the ATF attach and what type of sprain can tear it

attaches to lateral malleolus and to neck and lateral articular facet of talus
tears in inversion sprains

4

where does the posterior talofibular lig attch

lateral malleolus and to the lateral tubercle of post process of talus

5

where does the calcaneofibular lig attach

lateral malleolus to tubercle of lateral surface of calcaneus

6

is the ankle more stable in plantar flexion or dorsiflexion

dorsi

7

what are the major motions of the subtalar joint

ABduction or valgus
and Adduction or varus

8

what are the joints of the hind foot

talonavicular, talocalcaneal( subtalar)
calcaneocuboid

9

what happens in the foot during inversion

calcaneus adduction, navicular rotation and glide on talusto raise medial arch

10

what happens in foot during eversion

calcaneal ABduction, navicular rotation and glide on talus to raise lateral arch

11

Describe pronation of foot

eversion, dorsiflexion and ABduction

12

DEscribe supination of foot

Inversion, plantar flexion and ADduction

13

what is the primary motion of the inter metatarsal joints

sliding

14

What bones make up the lateral arch

calcaneus, cuboid 4th and 5th MTs

15

what bones make up the medial arch

calcaneus, talus, navicular, the cuneiforms and 1-3 MTs

16

What causes a high medial arch

ADduction of foot and varus calcaneus

17

What causes a dropped medial arch

ABduction of foot and valgus calcaneus and dorsiflexion (extreme pronation)

18

how many transverse arches are there

3, anterior posterior and tarsal

19

what causes flat feet

loss of tarsal arch

20

When evaluating an orthopedic injury which joints do you evaluate

1-3 joints up and down from injury

21

medial deviation of 1st MTP with lateral deviationa of proximal phalanx of hallux is what

bunion

22

describe the gait in regards to foot motion

heel strike, foot rolls laterally,weight rolls back to ant transverse arch, great toe should push toe off then swing phase

23

what ligaments are involved in acute inversion ankle sprain

anterior talofibular, calcaneofibular, posterior talofibular

24

What is the grading for a sprain

grade 1 microtears
grade 2 partial tears with decreased ROM
grade 3 complete tear with marked loss function and complete instability

25

What are signs of an inversion ankle sprain

swelling, eccymosis, TTP depending on degree, decreased ROM, antalgic gait, poor lower proprioception

26

what degrees do you get a + ant drawer test

2 and 3 degree

27

if arch is acutely flat after an inversion sprain what could be the problem

tibialis posterior tendon

28

what age group applies to ottawa ankle rules

above age 18

29

what type of sprain could cause foot drop

ankle inversion with fibular head moving posteriorly and lateral malleolus moves anteriorly

30

if you sprain your right ankle how will that affect sacrum

right on right sacral torsion, L5 will rotate opposite of the sacrum

31

What is the Tx differences between grade 1,2 tears with 3 tears

PRICE for 1&2
PRICESurgery for 3

32

function of lateral arch

to transmit weight and thrust to the ground
