MT: TF Suspension Flashcards
1
Q
Exoskeleton Advantage
A
more durable than soft coverings
2
Q
Exoskeletal disadvantages
A
- alignment and components are fixed
- changes require re-fabrication
- not commonly prescribed
3
Q
Suction Skin Fit
A
- Socket is slightlt smaller than limb
- soft tissues are compressed against the walls of the socket to create an air-tight seal
- creates hydrostatic pressure and axial weight bearing
4
Q
Suction Skin Fit Advantages
A
- least amonut of pistoning
- better proprioception
- feels lighter
- no straps or belts
5
Q
Suction Skin Fit Disadvantages
A
- Difficult to don
- hot
- requires consistent RL volume
6
Q
Suction Skin Fit Indications
A
- stable RL volume
- long RL, good skin, UL function
7
Q
Suction Skin Fit Cautions
A
- unstable RL volume
- fragile skin,scaring
- difficulty donning
- limited access to follow-up care
8
Q
Suction Liner Indications
A
- most patients
- easier to don than hard socket suction
- custom designs rarly necessary
9
Q
Suction Liner Cautions
*
A
- skin reaction
- distal skin traction can sometimes be uncomfortable
10
Q
Locking Liner Advantages
A
- effective suspension
- easy to don
- reduces shear forces
- sock ply accommodates volume change
11
Q
Locking Liner Limitations
A
- less rotational control than suction hard socket
- adds bulk, weight, cost
12
Q
Straps: Silesian Belt Indications
A
- common auxiliary suspension
- aid in rotational control
- may improve adduction
13
Q
Straps: Belt Limitations
A
- increase donning time
- encircles waist, inconvenient for toileting
14
Q
Straps: Suspenders Indications
A
- satisfied previous wearers
- nothing else will work
- must reuce forces around pelvis
15
Q
Hip Joint and Pelvic Band
A
- single axis hip joint laminated into the socket
- pelvic band positioned between iliac crest and trochanter
- leather belt with buckle
- usually involves sock fit
