Question 1

What is the ideal shape for a transtibial residual limb?

Answer 1

Cylindrical

Question 2

What is the ideal shape for a transfemoral residual limb?

Answer 2

Conical

Question 3

The removable rigid dressing (RRD) for the transtibial amputee offers what benefits? Ex: AmpuShield

Answer 3

Provides good edema control Ability to remove and allow for daily wound inspection (The RRD consists of a plaster or fiberglass cast suspended by a stocking and supracondylar cuff. Can adjust by +/- socks to maintain compression)

Question 4

What is the purpose of elastic shrinker socks?

Answer 4

Provide uniform compression generally after staples or sutures removed. Should fit snugly and reach the groin in transfemoral amputee

Question 5

What are some goals for the post op pre-prosthetic patient?

Answer 5

1. Pain control 2. Prep of residual limb for prosthetic fitting 3. Maintain and optimize ROM 4. Mobility, ADLs 5. Education about prosthetic fitting and care 6. Muscle strengthening (glut med & max, any residual hamstring or quads, UE)

Question 6

How often should an amputee wear a shrinkage device?

Answer 6

24 hours per day other than bathing Helps control pain & edema Facilitates healing

Question 7

What is the functional K level for the following LE amputee? Non ambulatory (bed bound)

Answer 7

K0 - no prosthesis

Question 8

What is the functional K level for the following LE amputee? Limited to transfers or household ambulation

Answer 8

K1 - Manual lock or stance-control knee, SACH or single-axis foot

Question 9

What is the functional K level for the following LE amputee? Unlimited household but limited community ambulator

Answer 9

K2 - Pneumatic or polycentric knee, multi-axis foot

Uneven surfaces

Question 10

What is the functional K level for the following LE amputee? Unlimited community ambulator

Answer 10

K3 - Hydraulic knee, energy-storing foot

Variable candence (speed up slow down)

Question 11

What is the functional K level for the following LE amputee? High energy activities (sports, work)

Answer 11

K4 - Hydraulic knee, energy-storing foot

Question 12

What type of prosthesis are typically used for partial foot amputations (ex: Great toe amputation, forefoot amputation)

Answer 12

Toe fillers with insole to provide ache support Shoe fillers or shoe modifications Rocker sole or AFO

Question 13

In the Syme’s amputation, preservation of articular cartilage covered by the heel pad. This allows for direct end bearing on the residual limb. What are the prosthetic feet available for a Syme’s amputation?

Answer 13

Syme solid ankle cushion heel (SACH) Syme stationary ankle flexible endoskeleton (SAFE) Energy-storing carbon fiber foot (low profile)

Question 14

What are the componenets in a BKA prosthesis?

Answer 14

Suspension

Socket

Shank

Prosthetic foot

Question 15

What is the average standard socket used for BKA amputee? Where is most of the weight-bearing?

Answer 15

Patellar tendon bearing socket (PTB)

Custom molded socket that distributes weight through covex areas such as the patellar tendon

Question 16

What are the pressure tolerant aras of a patellar tendon bearing socket?

Answer 16

1. Patellar tendon
2. Pretibial muscles
3. Popliteal fossa (gasroc-soleus m.)
4. Lateral shaft of the fibula
5. Medial tibial flare

Question 17

What are the pressure-sensitive areas (relief areas) of the patella tendon bearing socket?

(aka pressure sensitive areas)

Answer 17

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

Question 19

What is the leading cause of amputation in UE ?

Answer 19

Trauma

Question 20

What is the most common level of amputation in the UE?

Answer 20

Transradial

Allows high level of functional recovery
