Flashcards in 04 Foot/Ankle Palpations: Lateral Deck (44):
1

lateral 5th phalanges: clinical significance

- can be fractured or sprained at IP or MTP joints
- OA

2

5th MTP joint: clinical significance

- sprains
- bunion formation

3

5th metatarsal: clinical significance

stress fractures

4

5th styloid process: clinical significance

- common site for Jones fx

5

What is the 5th styloid process a landmark for?

figure 8

6

5th styloid process fractures

- can be a straight fx
- can be avulsion fx

7

What would cause an avulsion fx at the 5th styloid process?

insertion of the peroneus brevis tendon

8

What is the soft spot behind the 5th styloid process called?

cuboid groove (it's where the cuboid bone is)

9

cuboid groove clinical significance

- cuboid syndrome
- site of cuboid manipulations (cuboid whip)

10

What can be a cause for cuboid syndromes?

- ankle sprains
- overuse (dancers)

11

cuboid syndrome symptoms

pain with walking, movement, and palpation

12

cuboid syndromes and radiographs

doesn't show up

13

lateral side of the calcaneus to the tip of the fibula: clinical significance

- compression fx (MOI jump and land funny)
- will be symptomatic on palpation

14

What is one body inch inferior and anterior to the tip of the lateral malleolus?

Peroneal tubercle (little bump)

15

peroneal tubercle: clinical significance

- where peroneus longus and brevis bifurcate
- retinaculum

16

retinaculum over the peroneal tubercle

if it ruptures, the peroneal tendons can subluxate

17

What is the landmark where the achilles inserts?

dome of calcaneus

18

dome of calcaneus: clinical significance

Sever's syndrome

19

Sever's syndrome

- type of apophysitis of the physis similar to Osgood Schlatter disease
- tendon pulls on the calcaneal growth plate
- symptomatic to palpation

20

The anterior edge of the distal fibula is the attachment site for:

anterior talofibular ligament (ATF)

21

anterior edge of distal fibula: clinical significance

- avulsion fx can occur
- most common site of injury in the ankle

22

distal tib-fib joint: clinical significance

location of high ankle sprains

23

Where is the CF ligament?

runs from the posterior tip of the lateral malleolus toward the floor

24

CF ligament: clinical significance

- avulsion fx with a plantarflexion inversion injury
- Salter Harris type I fx in kids

25

What ligament attaches to the posterior tip of the lateral malleolus?

posterior talofibular ligament (PTF)

26

posterior talofibular ligament: clinical significance

- rarely injured
- can be an avulsion fx

27

superior lateral malleolus: clinical significance

common site of a Pott's fx or type 1 Salter Harris fx

28

head of the fibula: clinical significance

Maisonnueve fracture

29

Maisonnueve fracture

- may occur with an ankle sprain, esp if there was twisting
- mini spiral fracture near the head of the fibula

30

How to palpate the anterior lateral dome of the talus

- from lateral malleolus, go to anterior tip
- plantarflex the foot and invert it
- place finger on dome of talus

31

dome of talus: clinical significance

- common site of OCD
- chip fracture
- osteochondritis dessicans of the OCD lesion

32

chip fracture

with traumatic ankle sprain, superior lateral - talus hits the fibula and causes a chip fracture

33

What is a bunion at the 5th MTP joint called?

Tailor's bunion

34

differentiating peroneus longus/brevis: BREVIS

- runs from 5th styloid process
- anterior to peroneal tubercle
- closest to the fibula (behind lateral malleolus)

35

differentiating peroneus longus/brevis: LONGUS

- dives under cuboid groove area
- inferior to peroneal tubercle
- inferior to lateral malleolus

36

peroneus longus/brevis: clinical significance

- tendonitis/osis
- strains
- tears
- avulsion
- subluxation of peroneal tendons

37

What structure is over the peroneal tubercle?

lateral retinaculum

38

lateral retinaculum: clinical significance

- runs over peroneal tendons to stabilize
- can't be felt, but if the peroneal tendons subluxed, you'd know it was injured

39

How to palpate the peroneus longus and brevis

- evert
- plantarflex

40

sulcus in front of the lateral malleolus

sinus tarsi

41

sinus tarsi: clinical significance

ATF inserts at the bottom of the groove

42

distal tib-fib ligament: clinical significance

diastasis/syndesmotic injury (high ankle sprain)

43

ATF involvement in ankle sprains

involved 85% of the time with ankle sprains

44

CF injury in ankle sprains

- rarely get isolated CF injury
- usu injured sequentially after the ATF
