1

Standard TT Bench Alignment

-5 Deg socket flexion
-5 Deg socket adduction
-top of Px foot is level in both of saggital and frontal plane
-medial border of foot parallel to line of progression

2

List 4 prosthetic causes for rapid knee flexion

socket too far anterior
heel lever too long
different heel heights
stiff heel action

3

List 2 types of Symes Prostheses with advantages and disadvantages

1. canadian/VAPC-Advantage: don prosthesis easily, medial door stronger than posterior
2. expandable wall- Advantages: easy to don, no closures, good for the blind. Disadvantages: limited strectch

4

what causes TT px to appear to be higher than sound leg when sitting?

Posterior brim too high
not enough hamstring relief
incorrect length

5

What causes anterior distal tibia pressure?

AP to big
Post-brim too low
not enough relief
excessive use of knee extension
heel lever to long
excessive initial socket flexion

6

List 2 causes of distal limb edema and discoloration

Lack of total contact
short socket

7

What is the purpose of the 5 Deg of flexion and adduction in the socket during bench alignment?

5 deg of flexion:
-in order to elongate the quads so they are better equipped to accept the full weight of the body and aid in shock absorption during loading response.
5 deg of adduction:
-ensures that the foot is sufficiently inset to create the appropriate varus moment during stance which loads the residual limb properly.
