Flashcards in 04 Ankle 3 Deck (31):
1

bursae that affect the achilles tendon

- retrocalcaneal
- subcutaneous

2

retrocalcaneal bursa

more involved in overuse

3

subcutaneous bursa

more involved in footwear

4

What is an equinas foot?

lacking at least 10˚ dorsiflexion

5

comorbidities of achilles tendonitis/osis

- heel spur syndrome
- plantar fasciitis
- Haglund's deformity

6

tendon strain grades

3

7

common causes for achilles tendon rupture

- steroids
- chronic tendonitis

8

steroids and achilles tendon rupture

- steroid injections weaken tendons
- associated with increased instance of tendon rupture

9

When can steroid injections be done for a tendon?

- should never inject into a tendon
- can do peritendon injections under fluoroscopy

10

positive achilles tendon rupture test: gastrocs

If you squeeze the gastrocs and the foot doesn't PF, it's a positive test

11

positive achilles tendon rupture test: palpation

If there's a drop when you run your finger down the tendon area, it's a positive test

12

What else is a possibility with an achilles rupture?

avulsion fracture

13

treatment options

- closed reduction
- open reduction

14

closed reduction for achilles rupture

cast in PF

15

open reduction for achilles rupture

surgical repair

16

literature on closed vs open reduction for achilles rupture

- lit says they're the same outcome
- Davies says closed reduction has higher instance of reinjury

17

rehab for achilles tendon rupture: overall

foot is cast in PF post surgery, progressed to CAM walker

18

CAM walker

controlled ankle motion

19

rehab for achilles tendon rupture: By 3 months

- progress from NWB to WB
- move from splint to CAM walker to shoe

20

rehab for achilles tendon rupture: 2 weeks

ROM program after 2 weeks

21

rehab for achilles tendon rupture: 4 weeks

gentle strengthening, then increase

22

Haglund's syndrome

"pump bump"

23

nerves top to bottom implicated in tarsal tunnel syndrome

- medial plantar n.
- lateral plantar n.
- medial peroneal n.

24

surgery for tarsal tunnel

tarsal tunnel release - cut the flexor retinaculum

25

PTTD

posterior tibial tendon dysfunction

26

Who often gets PTTD?

- older
- deconditioned
- overweight

27

What does the posterior tibialis tendon do for the arch?

provides dynamic support

28

What happens in PTTD?

posterior tib is not providing dynamic support to the arch

29

PTTD: calcaneus

valgus calcaneus and excessive pronation

30

PTTD: hypertrophy of this muscle

abductor hallucis

31

total ankle reconstructions: are they done?

yes, but very rarely
