FINALS: Lower Extremity Prosthesis Flashcards
Q: What is the primary goal of preoperative management in amputations?
A: To prepare the patient physically and psychologically for surgery and prosthetic use.
Q: What is myoplasty?
A: Muscle-to-muscle attachment, used in amputation surgery; faster and simpler than myodesis.
Q: What is the purpose of a rigid dressing post-amputation?
A: Controls edema, protects the residual limb, and allows early prosthetic fitting.
Q: What is myodesis?
A: Muscle-to-bone attachment; provides better stabilization but takes longer.
Q: Why is preoperative counseling important?
A: It helps reduce anxiety, promotes understanding of rehab goals, and supports mental preparation.
Q: How do other amputees help in psychological recovery?
A: Peer support offers motivation, emotional support, and real-life perspective.
Stores/releases energy, springy feel, good for active users.
Energy-Storing Foot
Q: What is a positive indicator for transtibial amputation healing based on TcPO2?
A: TcPO2 > 35 mmHg at the calf.
Q: When is early amputation preferred over limb salvage?
A: When functional benefit is unlikely with limb salvage.
Q: What dressing offers best edema control and protection?
A: Rigid dressing.
A sock-like compression garment; easy to use but more expensive, worn 24/7.
Elastic shrinker
Q: What is the least effective shrinking device?
A: Elastic bandages.
Q: When is a preparatory prosthesis typically fitted?
A: 10–14 days post-surgery if the wound is closed.
Q: What are the goals of prosthetic training?
A: Realistic, individualized outcomes including ROM, ambulation, and ADLs.
Q: What is the first phase of gait training?
A: Initial gait training in parallel bars with balance and weight shifting.
Q: What are advanced gait training activities?
A: Walking on level surfaces, ramps, stairs, and learning falling techniques.
Q: How long is a preparatory prosthesis typically worn?
A: 3–6 months post-surgery.
Q: When is a definitive prosthesis replaced?
A: Every 3 years or with weight change of ±5 lbs.
Cushioned heel simulates PF, lightweight, good for elderly and kids.
SACH foot
Allows DF, PF, inversion, eversion, rotation; good for uneven ground.
Multi-axis foot
Allows DF/PF via bumpers; more stable knee; heavier than SACH.
Single-axis foot
Light, shock-absorbing, for moderately active or obese amputees.
