Thomas Test
Previous Prosthetic History
ive two advantages and disadvantage to a TSB socket - CORRECT
G
ANSWER-Advantages: No need for reliefs or accentuated pressure, use of roll on liner
for increased cushion/reduction of shear forces
Disadvantages: May lose rotation control, patient must be able to don and clean liners
(hygenic)
, ive two advantages and disadvantage to a PTB socket - CORRECT
G
ANSWER-Advantage: Use of pelite liner, low maintenance, rotational control
Disadvantage: Patient may not be able to tolerate pressures, may not control fatty limbs
ive two advantages and disadvantages to suction socket w/valve - CORRECT
G
ANSWER-Advantages= greater proprioceptive feedback, less pistoning
Disadvantages: requires sleeve which adds bulk, sleeve can get holes which causes
failure in system
ive two advantages and disadvantages to roll on locking liner - CORRECT
G
ANSWER-Advantages= audible confirmation of suspension, quick suspension (fewer
steps), all benefits of liner, good for low activity patients or those who need assistance
Disadvantages= Pistoning, requires hand dexterity to don, need to be replaced every 6
months
ive two advantages and disadvantages to pure sleeve suspension - CORRECT
G
ANSWER-Advantages: Good auxiliary suspension, simple, can be cosmetically
appealing,
Disadvantages: adds an additional layer of material bulk behind knee, hot, quickly get
holes
ive two advantages and disadvantages to Roll on gel liner w/seal - CORRECT
G
ANSWER-Advantages= greater surface area of contact that prevents pistoning, control
edema on distal end, no sleeve required allows for more knee flexion
Disadvantages: little tolerance for limb volume fluctuations, requires push valve that can
cut pants, requires more maintenance
ive two advantages and disadvantages to roll on gel liner w/ elevated vacuum -
G
CORRECT ANSWER-Advantages: limb volume control, limb health, better
proprioception, increased control of socket
Disadvantages: expensive, higher risk of creating blisters if not fit properly, more exact
fit required
ive two advantages and disadvantages to supracondylar + Suprapatellar - CORRECT
G
ANSWER-Pro: provides A/P stability, Provides M/L stability, limits recurvatum,
Con: Supra-patellar bar can be uncomfortable, can limit knee motion
hat is the attachment site of a supracondylar cuff strap - CORRECT ANSWER-12mm
W
posterior to midline and 12 mm proximal to MTP(medial tibial plateu
