1

What are the four socket designs for transfemoral amputees

quadrilateral
ischial containment
Marlo Anatomical
Elevated Vacuum

2

What type of socket is used with a subischial amputation

elevated vacuum

3

A quadrilateral socket has ___ distinct walls

4

4

A quadrilateral socket has a _____ ____ which is an ischial seat or the primary weight-bearing surface

posterior shelf

5

The (anterior/posterior) wall contours direct forces (anterior/posterior) to try to stabilize ischium on its prosthetic seat

anterior; posterior

6

True or False:

A quadrilateral socket is narrower M-L than it is A-P

false, more narrow AP

7

Why is a quadrilateral socket more narrow AP than it is ML

Because its trying to push the ischium back to its shelf/ischium seat

8

What type of socket was made to try to control an abducted residual femur

Ischial containment

9

An ischial containment socket was created to control a femur that is (adducted/abducted)

abducted

10

Long's line, CAT-CAM, and ischial ramal containment are what type of transfemoral sockets

ischial containment

11

Which type of socket attempts to encapsulate the ischial tuberosity as well as portions of the ramus with a very distinguishable containment buttress

marlo anatomical socket

12

A Marlo anatomical socket has a (lower/higher) posterior trim line to make it easier to sit on the glute instead of the posterior socket

lower

13

A Marlo anatomical socket has a low (anterior/posterior) trim line as well as a low (medial/lateral) trim line

to make it easier to sit on the glute instead of the socket

14

Why does a Marlo anatomical socket have a low medial trim lines and a high lateral trim line as opposed to a high medial and low lateral trim lines

The high lateral trim line helps control/contain the ischium and the low medial trim line aid in the flattening of the thigh while seated

15

A Marlo anatomical socket (does/does not) limit ER, so there (is/is not) a need for a rotation unit proximal to the knee joint

does not, is not

16

What is another name for an elevated vacuum socket

subischial socket

17

An elevated vacuum/subischial socket has (low/high) trim lines, (decreased/increased) patient comfort, (decreased/increased) patient ROM, and proximal trim lines that are lowered by __-__ inches

low; increased; increased; 2-4

18

An elevated vacuum/subischial socket has ___ trim lines
Increased ____ ____
Increased patient ____
and (proximal/distal) trim lines that are lowered 2-4 inches

low
patient comfort
ROM
proximal

19

A weaker limb will need a prosthetic with a (lower/higher) design

higher

20

In general, what are the two types of socket materials

rigid and flexible

21

(rigid/flexible) socket material is usually resin-laminated or thermoformed plastic that is intended to have an intimate, total contact fit

rigid

22

What are the five characteristics of a rigid socket material

durable
easy to clean
less bulky (not really though)
less expensive
difficult to adjust

23

True or False:

A socket with rigid material leaves little to no room for additional socks or cushion outside of what the socket provides

true

24

(rigid/flexible) socket material is vacuum formed with any number of flexible thermoplastic materials

flexible

25

Flexible socket material is incased in a rigid frame that provides support with ___ and helps keep socket ___

WB; shape

26

is rigid or flexible material more comfortable, especially in sitting

flexible

27

Which type of socket material is used if suction suspension is desired

flexible

28

Which type of socket material is more durable than the other

rigid is more durable than flexible

29

Which type of socket material is bulkier than the other

flexible is more bulky than rigid

30

Which socket material is more expensive than the other

flexible is more expensive than rigid 9
