The flashcards below were created by user alannaheeres on FreezingBlue Flashcards. What would you like to do?


  1. 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
  2. What are diabetic foot ulcers usually caused by? (3)
    Impaired sensation

    Structural abnormalities

    Poor blood flow to injured area
  3. What are the primary causes of amputations? (6)
    • Trauma
    • Frostbite
    • Cancer
    • Congenital
    • Infection
    • Burns
  4. Are lower or upper limb amps more common for dysvascular amps?
    Lower (97%)
  5. Impact of ray resection or partial foot (2)
    • Endurance - body has to work more to balance itself
    • Righting reactions
  6. Problem with walking on Syme's
    There will be leg length discrepancy -> over time will affect hip, pelvis and spine
  7. Why do BKs require a manual wheelchair?
    for resting legs for day/week/month to prevent wounds
  8. Most common lower extremity amp
    BK
  9. 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
  10. used for edema management, similar to pressure gradient stocking
    Juzo sock
  11. Aids in preventing flexion contractures
    Limits swelling of amputated limb
    Amputee board
  12. Primary focus of bilateral BKA
    transfers -- start with either a slide board or a front-on transfer
  13. Why are stubbies used at first for AK Prothesis? (2)
    • Low centre of gravity, good for falls
    • Increases hip strength
  14. Locks in extension
    Provides maximum stability
    User can release the knee manually
    Used with weak, unstable and bilateral amputees
    Single Axis-Locked Knee
  15. No automatic lock in extension
    Lightest and most durable above knee prosthesis
    Single Axis - Free Knee
  16. 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
  17. Allows for variable gait speeds
    Very stable in stance phase
    Heavy, costly and require frequent maintenance
    Good for very active people
    Hydraulic Knee
  18. Onboard sensors detect movement and control the knee accordingly
    Goal is more natural gait pattern and improved function with non-walking tasks
    Microprocessor Knee
  19. Wheelchair hanger angle for BKA
    70, sometimes 80 degrees
  20. Wheelchair hanger angle for AKA
    60 degrees
  21. Can Right AKAs use their prosthesis to drive?
    NO
  22. 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
  23. Pre-prosthetic Therapy Program (5)
    • Residual limb shrinkage and shaping
    • Residual limb desensitization
    • Maintenance of joint ROM
    • Education on limb hygiene
    • Maximizing functional independence
  24. Prosthetic Therapy Program (6)
    • Gait re-training
    • Sock selection
    • Stump inspection
    • Balance 
    • Functional Transfer
    • Educate on cleaning instructions
