1

What is a Lisfranc's amputation?

Amputation through tarsometatarsal junction

2

What ABI indicates mild PAD?

0.7-0.9

3

What is considered long, standard and short AKA?

Long = >60% residual limb
Standard = 35-60% residual limb
Short = <35% residual limb

4

MCC of amputation ages 15-50

Trauma

5

What is considered a long, standard and short BKA?

Long = >50% residual limb
Standard = 20-50% residual limb
Short = <20%

6

Gold standard imaging test for PAD

Intraarterial contrast angiography

7

MCC of amputation in ages 0-5

Congenital deformity

8

What's the shortest BKA you can have with residual limb still being functional?

1cm below tibial tuberosity

9

What is a syme's amputation?

Ankle disarticulation

10

Hip disarticulation vs hemipelvectomy vs hemicorpectomy

Hip disarticulation = pelvis remains in tact
Hemipelvectomy = resection of lower half of pelvis
Hemicorpectomy = amputation of both lower limbs and pelvis

11

Myodesis vs myoplasty

Myodesis is when muscle is sutured to bone.
Myoplasty is when muscles are sutured to each other

12

What is considered too high of an ABI and may be considered abnormal?

>1.3. May indicates calcified noncompressible vessels

13

What are 2 unsatisfactory levels of amputation for a BKA?

1. Amputation through distal 2/5 of tibia (60% of residual limb) - below the gastroc-soleus
2. Very short BKA - above the tibial tuberosity

14

What ABI indicates severe PAD

<0.4

15

What ABI indicates moderate PAD?

0.4-0.7

16

What is considered an unsatisfactory AKA level?

Very short AKA with Amputation through just below lesser trochanter

17

MCC of amputation in ages 5-15

Cancer or trauma

18

When a patient has dysvascularity and myodesis is contraindicated, what is the procedure of choice?

Myoplasty

19

What is a contraindication to myodesis?

Dysvascularity

20

If ABI screening for PAD is abnormal, what test can be done to localize the lesion?

Doppler velocity waveform analysis

21

What is a Chopart amputation?

Amputation through the tarsal bones, sparing the calcaneus and talus

22

What is considered normal ABI?

0.9 - 1.3

23

An ankle pressure of what indicates limb threatening ischemia?

<50 mmHg
