Transfemoral Suspension Flashcards
1
Q
What are the four generic suspension groups?
A
- Atmospheric Pressure (suction)
- Anatomic
- Strap
- Hinge
2
Q
What are examples of suction socket?
A
- Socket with Valve
- roll on locking liner
- hypobaric sock
- vacuum
3
Q
What is the primary indication, major advantages and disadvantages for suction sockets?
A
- Whenever clinically feasible
- minimizes pistoning, best proprioception, greatest ROM
- precise fit, consistent donning necessary, works best with stable residual limb
4
Q
What are examples of anatomic sockets?
A
-Supracondylar wedge for knee Disart
5
Q
What is the primary indication, major advantages and disadvantages for anatomic sockets?
A
- KD or congenital malformations
- good suspension, rotational control
- suspension pressure is localized
6
Q
What are examples of strap sockets?
A
- silesian belt (TES)
- prefab elastic suspension belts
7
Q
What is the primary indication, major advantages and disadvantages for strap sockets?
A
- Residual limb volume changes anticipated
- amputee-adjustable, good axiliary suspension, controls rotation
- some pistoning, belt may be uncomfortable, donning properly takes skill
8
Q
what are examples of hinge sockets?
A
-pelvic joint and belt
9
Q
What is the primary indication, major advantages and disadvantages for hinge sockets?
A
- short residual limb or weak hip abductors
- max ML/AP support, partial rotational control
- heavy, bulky, awkward to don, allows significant pistoning, can be uncomfortable when sitting.
