1

How long is a temporary prosthesis usually used for?

3-6 months after surgery

2

Which BKA suspension is fitted immediately above the femoral epicondyles and can be used with or without a fork strap and waist-belt

Supracondylar cuff suspension

3

What kind of prosthesis does a patient with a small toe amputation need?

Usually no prosthesis is needed

4

For syme's prosthesis, how far up should trim line go?

To the patellar tendon

5

What BKA suspension is used when patellar tendon can't tolerate weight or when knee joint is unstable

Thigh corset

6

What is the benefit of a supracondylar brim suspension?

Better mediolateral support

7

3 prosthetic feet available for syme's amputation

1. Solid Ankle Cushion Heel (SACH foot)
2. Stationary Ankle Flexible Endoskeleton (SAFE foot)
3. Energy-storing carbon fiber (low profile foot)

8

Which BKA suspension has medial and lateral walls extending above the femoral epicondyles

Supracondylar brim suspension

9

What BKA suspensions can be used for athletes?

Suction and pin

10

What is a disadvantage of using a sleeve suspension for BKA?

Increased perspiration

11

Which BKA suspension do you use to prevent genu recurvatum?

Supracondylar-suprapatellar brim suspension

12

3 socket design options for syme's amputation

1. Posterior opening
2. Medial opening
3. Stovepipe

13

Which BKA suspension provides the most medial-lateral and anterior-posterior stability

Thigh Corset

14

How is the PTB socket aligned?

Slight flexion and slight lateral tilt

15

Disadvantage of supracondylar cuff suspension

Minimal medial-lateral stability and considerable pistoning

16

Is the medial or the lateral tibial flare a pressure-tolerant area?

Medial tibial flare

17

5 pressure-sensitive areas when using a patellar tendon bearing socket

1. Tibial crest, tubercle and condyles
2. Fibular head
3. Patella
4. Hamstring tendons
5. Distal tibia and fibula

18

What kind of prosthesis does a patient with a great toe amputation need?

Stiff sole, toe filler, molded insole, arch support

19

Most commonly used socket for BKA

Patellar Tendon Bearing Socket

20

What is the advantage of a suction BKA suspension?

Does not create pressure distributions

21

What is the main disadvantage of syme's amputation prosthetic fitting

Poor cosmesis because of the bulbous distal residual limb

22

Disadvantage of thigh corset

Very heavy and not well tolerated
