Prosthetic Components Flashcards
endoskeleton
interchangeable and adjustable
good for children
flexible foam cover
exoskeleton
components covered with hard lamination
goal of the patellar tendon bearing (PTB) socket
apply pressure to pressure tolerant areas, while relieving pressure in sensitive areas
what is a check socket?
clear plastic, not pernament
how many socks is too many?
more than 10
Which areas are considered pressure tolerant?
patellar tendon medial tibial flare calf muscle belly distal end tibia shaft of fibula medial tibial condyle
Which areas are sensitive to pressure?
tibial crest anterior distal tibia fibular head and distal cut of fibula lateral tibial condyle*** hamstring tendons
Which socket interface provides the best control?
suction socket
What is the socket interface?
liner between the residual limb and socket to cushion or protect limb
advantage of supracondylar sockets?
provides medial lateral stability
free moving patella
Disadvantage of supracondylar socket?
may be difficult to don d/t narrow opening
cosmesis of high M-L walls in sitting
Advantage of supracondylar suprapatellar socket
good for short residual limb
adds stability by enclosing patella
Cons of supracondylar suprapatellar socket
kneeling difficulty
poor cosmesis in sitting
difficulty to fit a lot of fleshy tissue
supracondylar cuff suspension pros
easy to don
simple durable
cons of supracondylar cuff suspension
not good for short residual limb
or those who have poor vasculature supply b/c of high forces in sitting
pros of thigh corset and knee joints
good for short residual limbs, unstable knees, can decrease weight through residual limb and can control knee hyper extension
cons of thigh corset and knee joint
heavy
poor cosmesis
what is the most common form of transtibial socket?
shuttle pin design
pros of sleeve suspension
cosmetic
airtight
unrestricted knee motion
minimal pistoning
cons of sleeve suspension
not durable
skin hygiene problems
need good hand function to don/doff
