1

artificial replacement of body part

prosthesis

2

time periods of prosthesis

temporary (within year)
definitive

3

What are the components of transtibial and transferal prostheses

shank/pylon
socket
suspension

4

Description of K0-

K0: Non ambulatory
K1:Limited household ambulation
K2:Limited community ambulation
K3:independent community/leisure ambulation
K4: High level activity.

5

Conventional feet are

not very mobile K0-1

6

3 kinds of conventional feet

SACH foot
SAFE Foot
Single axis

7

long lever=

short lever=

less stability more energy return

More stability less energy return

8

What are some dynamic response feet?

non-articulated short/long lever
articulated long keel
polycentric
hydraulic ankle
torsion absorbtion
running

9

What is the purpose of a split keel?

reaction to different surfaces

10

Hydraulics controls

PF from initial contact thru LR

11

How is energy stored in hydraulic ankle?

when pylon DF over foot during stance

12

What does torsional absorbtion foot do?

whats this good for?

translates rotational force through foot

golf softball

13

pylons can be

endoskeletal
exoskeletal

14

Characteristics of pylon

transfer weight
Shockabsorber
can add rotator
restore length

15

Characteristics of socket

provide total contact
Counter-pressure for venous control
sensory feedback

16

Materials and methods of making socket

Casting vs CAD-CAM

Thermoset (resin)vs thermoplastic.

17

What are WB areas of patellar tendon bearing prosthesis??

patellar tendon
Gastroc
Pretibial muscles
Tibia& fibular shaft.

18

Most sockets for transtibial used with

what does it do

silicone liner

provides cushion

19

Where is there pressure in socket for transfemoral?

ischial tub
glutes
Ramus
side of thigh

20

Where should u avoid pressure for transferal Prosthesis

pubic symphysis
perineum
adductor longus tendon

21

Transferal prosthesis set in

slight flexion (5 deg)
and adduction (7 deg)

22

Quadrilateral transferal socket has WB on?

why is ant wall higher?

what is limiting in it?

ischemic tub

counter-pressure

M-L/rotational stability

23

WB on ischial containment socket?

what is improved?

ischium and ascending ramus

M-L rotational stability secondary to high lateral wall

24

Types of transferal sockets?

quadrilateral
ischial containment
contoured ischial containment

25

What does contoured ischial containment socket do

contour for hammys and adductors to allow for muscle enlargement

26

What are the suspensions of transtibial prostheses

Supracondylar cuff
Neoprene sleeve
Shuttlelock + Pin
supracondylar wedge
thigh corset

27

Suspensions for transferal prostheses

total suction
shuttlecock + Pin
partial suction (sock and band)
no suction (use bands)

28

What are the knee units of transferal prostheses?

possible components?

single axis or polycentric

mechanical stabilizer
microprocessor
extension aid

29

Align knee posterior to TKA line, manual lock, friction brake

mechanical stabilizer

30

What is contstant vs fluid friction

constant: swing value

fluid: hydraulic or pneumatic

31

Types of socks/sheaths?

cotton
wool
nylon
silicone

32

when should u use smaller socket?

after 7 ply

33

Removable medial or posterior compartment to accommodate bulbous distal end?
