Exam Study Guide

Question 0

TT bench alignment:

Answer 0

5 degrees of flexion
5 degrees of adduction
Foot inset up to 1/2”
Lateral reference line should fall 1 1/4” anterior to foot bolt
Medial border of foot follows line of progression

Question 1

What causes lateral and distal redness?

Answer 1

Socket too large.

Question 2

What causes proximal lateral and distal medial redness:

Answer 2

Adducted socket

Socket M/L too large

Question 3

Patient bottoms out secondary to?

Answer 3

Decrease in residual limb volume
Patient not donning enough socks
Socket made too large initially
Lack of contact distally causing verrucous hyperplasia.

Question 4

What causes fib head redness: Adequate relief not made for the fib head.

Answer 4

Adequate relief not made for the fib head.

Question 5

6.What causes anterior proximal and posterior distal redness: Insufficient initial socket flexion
Shoe heel height decreased
Heel lever too short or heel cushion too soft

7.What causes anterior distal tib pressure: A/P too big 
Posterior brim too low 
Insufficient relief 
Excessive use of knee extension 
Heel lever too long 
Excessive initial socket flexion
8.Placement of thigh and corset joint: Average starting point is 2 1/4" superior to the patella tendon 
Slightly posterior 
Joints are tilted anteriorly

9.Resulting pressure of. Aligned knee center: Knee center to distal = anterior distal thigh and posterior proximal thigh pain
Knee center to proximal= knee center placed to proximally

10.Possible causes for TT prosthesis appearing higher than the sound limb when sitting: Posterior trims too high
Insufficient hamstring relief
Incorrect length

Answer 5

Insufficient initial socket flexion
Shoe heel height decreased
Heel lever too short or heel cushion too soft

Question 6

What causes anterior distal tib pressure:

Answer 6

A/P too big 
Posterior brim too low 
Insufficient relief 
Excessive use of knee extension 
Heel lever too long 
Excessive initial socket flexion

Question 7

Placement of thigh and corset joint?

Answer 7

Average starting point is 2 1/4” superior to the patella tendon
Slightly posterior
Joints are tilted anteriorly

Question 8

Resulting pressure of. Aligned knee center: Knee center to distal = anterior distal thigh and posterior proximal thigh pain
Knee center to proximal= knee center placed to proximally

Answer 8

Knee center to distal = anterior distal thigh and posterior proximal thigh pain
Knee center to proximal= knee center placed to proximally

Question 9

10.Possible causes for TT prosthesis appearing higher than the sound limb when sitting?

Answer 9

Posterior trims too high
Insufficient hamstring relief
Incorrect length.

Question 10

11.Cause of rapid knee flexion?

12.Possible. Amuses of distal limb edema or discoloration: Lack of contact in socket
Short socket

13.What deviation should be expected when converting pervious joint and corset users to PTB style socket: Excessive knee flexion
Medial lateral instability
Patient insecurities

Answer 10

Prosthetic socket is placed too far anterior
Heel lever excessively long
Patient heel height is increased
Excessively stiff heel action.

Question 11

12.Possible. Amuses of distal limb edema or discoloration:

Answer 11

Lack of contact in socket

Short socket.

Question 12

13.What deviation should be expected when converting pervious joint and corset users to PTB style socket:

Answer 12

Excessive knee flexion
Medial lateral instability
Patient insecurities.

Question 13

When a patient complains of anterior distal Tibet pain, what are the three question to ask? Have you changed your shoe heights, do you have new activities your doing, time of day the pain presents.

Answer 13

Have you changed your shoe heights,
do you have any new activities your doing,
time of day the pain presents.
