Trans Tibial Suspension Flashcards
1
Q
What are the four generic TT suspensions?
A
- Atmospheric Pressure (suction)
- Anatomic
- Straps
- Hinges
2
Q
Examples of atmospheric pressure (suction)
A
- Roll on locking liners
- hypobaric socks
- vacuum
- knee sleeves
3
Q
What is the primary indication, major advantages and disadvantages for suction sockets?
A
- Whenever clinically feasable
- minimizes pistoning, best proprioception, greatest ROM
- precise fit, consistent donning necessary, works best with stable residual limb
4
Q
Examples of anatomic sockets
A
-supracondylar wedge with or without suprapatellar extension
5
Q
What is the primary indication, major advantages and disadvantages for anatomic sockets?
A
-To increase knee stability for short residual limb or ligamentous laxity
6
Q
Examples of Strap Sockets
A
- Cuff
- cuff+waist belt
- fork strap + waist belt
7
Q
What is the primary indication, major advantages and disadvantages for strap sockets?
A
- Residual limb volume changes anticipated
- Amputee-adjustable, good auxiliary suspension
- Some pistoning, waist belt may be uncomfortable, tight cuff may impair circulation
8
Q
Examples of hinge sockets
A
-thigh corset (joints and lacer)
9
Q
What is the primary indication, major advantages and disadvantages for hinge sockets?
A
- Damaged knee or residual limb
- maximum ML and AP stability, partial unloading of residual limb
- Heavy, bulky, awkward to don, allows significant pistoning
