Px Suspension And Components

Front 1

list the most effective suspension to the least effective

Back 1

atmospheric pressure/suction, anatomical, strap, and hinge

Front 2

describe how atmospheric pressure suspension works

Back 2

socket held on by normal atmospheric pressure. to remove, amputee opens the valve and the outsid air has equalized the pressure inside the socket

Front 3

list 3 limitations to suction socket?

Back 3

1) inability to maintain vacuum seal,

2)inability to don/doff socket consistently

3) inability of skin to tolerate direct contact with the hard socket walls

Front 4

what types of suction sockets are there?

Back 4

atmospheric- with a valve to let air in and out; used with pull sock

internal roll -on locking liners (with lanyard or pin)

roll-on liner with one way valve and knee sleeve

liner and suction pump that is self energized during ambulation.

Front 5

to create an effective vacuum seal with a suspension sleeve, how much contact is need on the socket AND the skin

Back 5

2cm

Front 6

name 4 examples of TT atmospheric pressure suspension

Back 6

1) roll-on locking liner
2) hypobaric socks
3) augmented vacuum systems
4) elastomeric knee sleeves

Front 7

when is atmospheric pressure TT suspension indicated?

Back 7

whenever clinically possible

Front 8

advantages of TT atmospheric pressure suspension ?

Back 8

minimizes pistoning, best proprioception, greatest ROM

Front 9

Limitations of TT atmospheric pressure suspension?

Back 9

precise fit

consistent donning necessary

works best with stable limb volume

Front 10

name 2 types of TT anatomical suspension designs

Back 10

supracondylar wedge, with or without suprapatellar extension

Front 11

primary indication for anatomical TT suspension

Back 11

increase knee stability

short RL

Ligamentous laxity
