LE Prosthetics Flashcards
What are 6 components of a prosthesis?
Construction type (Exo or endo) Socket Skin interface Suspension Skin Foot/Ankle/Knee
When is exoskeletal construction recommended?
Only with morbidly obese patients
- Durability is only benefit
- Structural integrity is provided in rigid outer shell/foam interior
What is K0? (K QUESTIONS WILL BE ON THE QUIZ PER RIJO RAJAN AND JANICE)
No ability or potential to ambulate or transfer safely with prosthesis
What is K1?
Has ability or potential to use a prosthesis for transfers or ambulation on level surfaces at a fixed cadence (limited or unlimited household ambulator;; no community)
What is K2?
Has the ability or potential for ambulation with the ability to transverse most environmental factors ( a limited community ambulator.)
What is the main difference between K1 and K2, per class lecture?
Can they get over a curb or not? Can they leave the home?
What is K3?
Has the ability or potential for prosthetic ambulation with variable cadence (use beyond simple ambulation) (e.g. exercise) - unlimited community ambulator
What is K4?
Has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting high-impact, stress, or energy levels (athlete)
What is the one choice for Prosthetic shins?
Pylon: • Tube clamp adaptor • (allows transverse motion) • Vertical shock pylon • Variety of materials • Torque absorber • Weight rated
What are the 2 most common socket designs?
- Patella tendon bearing
2. Total surface bearing
Which is the most common TT socket design?
Total surface bearing
How do you want the LE weight line aligned?
You want an imaginary straight weight line though the trochanter, knee, and ankle
- Line can be slightly anterior to knee
- If line is posterior, it means you are stuck in flexion / no stability
