5.2- Amputation 2- Equipment Flashcards
BK- what is used as an important first step?
temporary BK prosthetic- fitted after would is healed, but before swelling is down
BK- why is walking an important initial consideration?
best way to decrease swelling and shape stump
BK initial considerations- What must be assessed?
- Ability to transfer in bed and wheelchair
- Cognitive state
- Family status
- Endurance
- Ambulate with walker without prosthetic
BK Fitting- ROM
Most have flexion contracture, if bad the prosthetist issues a _____ first. If minor, using the prosthetic will ______.
stretching program
stretch it out
How long does it take to make prosthetic from cast?
1-2 weeks
What are two types of BK sockets?
- Total contact socket
2. Patellar tendon bearing socket
- the shell that is in contact with the stump
- must be in complete contact with all areas of the stump, but no excessive pressure
- areas not in contact will swell excessively
Total Contact Socket
______ - occurs where not making total contact
Enduration (Brawny edema)
What should you do if too much contact of stump and prosthesis? (BK)
Add socks
PTB socket transfers body weight to ____, ____, and ____.
patellar tendon, anterior tib, gastroc
BK Suspension-
Waist belt not used much anymore. Supracondular cuff goes around the femoral condyles and is good for ______.
Knee hyperextension
What are the 4 types of suspension of BK?
- Waist belt
- Supracondular cuff
- Pin system
- Neopreen sleeve
What is the most common BK suspension?
Pin system- pin on distal end of the sleeve locks into the prosthesis
- can be use with permanent prosthesis
- rolled up leg, grips onto skin to hold up
Neopreen sleeve
What type of suspension is used with a vacuum system?
Neopreen sleeve
What type of suspension is good for preventing knee hyperextension?
Supracondular cuff
____- metal bar with foam over it to look like other leg and is very easy to adjust
Endoskeleton (most common)
___- hard outer covering made of plastic and is durable
Exoskeleton
What is a SACH foot?
Solid ankle, cushioned heel
- foot of choice for temporaries, older adults, kids
What is an advantage to a SACH foot? A disadvantage?
Advantage- cheap and durable
Disadvantage- can’t have a normal gait pattern b/c no DF/PF- unable to go up ramps, drive, or be an uneven terrain
What order do you follow to don a prosthesis?
- Liner
- Socks
- Pants
- Prosthesis
- Strap suspension
(6. Assess Pressure)
AK or BK?
Good cognition b/c they are learning a new gait pattern
AK
-rely on hip extension and weightbearing to keep artificial knee locked
How is an AK prosthesis fitted differently than a BK?
BK is casted.
AK has extensive measurements taken and based on those the person is put into a prefab socket
_____- has a posterior lip that allows the ischium to sit on it- where most of the body weight is loaded
Soft socket (AK)
______- uses suction to hold prosthetic onto stump
Suction socket
What type of suspension part doesn’t work with short residual limbs, vascular problems, people that have large variations in size of stump throughout the day?
suction socket
____- liner is rolled up the residual limb, the prosthetic is attached to the liner by a pin
Pin/shuttle
What are three types of knees?
- Mechanical friction (rarely used)
- Pneumatic and hydraulic
- Computerized knee
Foot and ankle~
- Older adults prefer using a _____
- Athletes prefer using a _____
- Runners prefer using a ______
- older adults- SACH (feel more secure)
- athletes- uniaxial & multiaxial ankles (much heavier)
- runners- numerous energy storing feet for runners
Prosthesis gait training always begins ______.
in the parallel bars
Gait training- practice ________ knee and work on ________ LE forward.
flexing and extending knee and work on lifting and placing LE forward
Teach AK to swing through with ___ and fully ____ in order to ______.
swing through with hip and fully weightbear in order to lock the knee
A vacuum system may help with _______.
wound healing
