-
Onset typically in 3rd to 5th
decade (age 30 to 50)
Starts distally in UE and/or LE
Smoking cessation halts disease
progression
Buerger's Disease
-
What are diabetic foot ulcers usually caused by? (3)
Impaired sensation
Structural abnormalities
Poor blood flow to injured area
-
What are the primary causes of amputations? (6)
- Trauma
- Frostbite
- Cancer
- Congenital
- Infection
- Burns
-
Are lower or upper limb amps more common for dysvascular amps?
Lower (97%)
-
Impact of ray resection or partial foot (2)
- Endurance - body has to work more to balance itself
- Righting reactions
-
Problem with walking on Syme's
There will be leg length discrepancy -> over time will affect hip, pelvis and spine
-
Why do BKs require a manual wheelchair?
for resting legs for day/week/month to prevent wounds
-
Most common lower extremity amp
BK
-
Why are tensor bandages used for stump wrapping?
- To control swelling in foot –used because of its durability and pressure
- Can redo during the day
-
used for edema management, similar to pressure gradient stocking
Juzo sock
-
Aids in preventing flexion contractures
Limits swelling of amputated limb
Amputee board
-
Primary focus of bilateral BKA
transfers -- start with either a slide board or a front-on transfer
-
Why are stubbies used at first for AK Prothesis? (2)
- Low centre of gravity, good for falls
- Increases hip strength
-
Locks in extension
Provides maximum stability
User can release the knee manually
Used with weak, unstable and bilateral amputees
Single Axis-Locked Knee
-
No automatic lock in extension
Lightest and most durable above knee prosthesis
Single Axis - Free Knee
-
Multiple axis of rotation
Overall length shortens when in swing phase, reducing risk of stumbling
More stable in stance phase and with heel strike
Decreases upper leg length discrepancy when sitting
Polycentric Knee
-
Allows for variable gait speeds
Very stable in stance phase
Heavy, costly and require frequent maintenance
Good for very active people
Hydraulic Knee
-
Onboard sensors detect movement and control the knee accordingly
Goal is more natural gait pattern and improved function with non-walking tasks
Microprocessor Knee
-
Wheelchair hanger angle for BKA
70, sometimes 80 degrees
-
Wheelchair hanger angle for AKA
60 degrees
-
Can Right AKAs use their prosthesis to drive?
NO
-
Postoperative Therapy Program (5)
- Promote wound healing
- Control incisional and phantom pain
- Maintain joint range of motion
- Aid with body image and psychosocial
- concerns
- Education on self- tensoring
-
Pre-prosthetic Therapy Program (5)
- Residual limb shrinkage and shaping
- Residual limb desensitization
- Maintenance of joint ROM
- Education on limb hygiene
- Maximizing functional independence
-
Prosthetic Therapy Program (6)
- Gait re-training
- Sock selection
- Stump inspection
- Balance
- Functional Transfer
- Educate on cleaning instructions
