How much of the femoral length remains in a Long Transfemoral Amputation?
>60%
35-60%
<35%
How much of the femoral length remains in a Standard Transfemoral Amputation?
How much of the femoral length remains in a Short Transfemoral Amputation?

20-60%
What are the advantages of a transfemoral amputation relative to the more distal amputations?
Greater Healing Rate
Easier socket fit
Shorter hospital stay
Less incidence of Phantom Pain
Less incidence of surgical complications
Gait training is easier
The quadrilateral socket for a transfemoral amputation allows for muscle contractions.
The Quadrilateral socket (TFA) is characterized by reliefs and bulges.
The Ischial Containment Socket is characterized by narrow medial / lateral diameter with greater width in the anterior / posterior dimensions
The Quadrilateral Socket (TFA) is characterized by narrow medial / lateral diameter with greater width in the anterior / posterior dimensions.
The Ischial Containment socket (TFA) is characterized by reliefs and bulges.
Stability of a Knee Unit is accomplished by which of the following?
Residual limb exerting a backward force within the socket
Residual limb exerting a forward force within the socket
Knee axis aligned posterior to the weight line
Knee axis aligned anterior to the weight line
Stance, braking or locking mechanism
Movement of the residual limb and pelvis
Gravity
Swing Control of a Knee Unit is accomplished by which of the following?
Momentum
Mechanical extension
Locking mechanism
Which of the following Swing-Phase Control Mechanisms are appropriate for K1 and K2?
Mechanical Friction
Pneumatic Control
Microprocessor Controlled Fluid Friction
Hydraulic Control
Which of the following Swing-Phase Control Mechanisms are appropriate for K3 and K4?
C-Leg and Genium are which type of Swing-Phase Control Mechanisms?
The Weight-Activated Stance Brake Knee (WASB) imparts a characteristic gait deviation and limits cadence to a single speed.
The Weight-Activated Stance Brake Knee (WASB) imparts a characteristic gait deviation, but is otherwise appropriate for K3.
Which Hip Joint Mechanism is described below? At toe off, knee flexion pulls the hip joint against the posterior extension stop. As the knee rotates forward the weight and slight pelvic posterior rotation flexes the hip. Because the prosthesis is at full length during mid swing the prosthesis must be significantly shortened to permit toe clearance, however, most amputees tend to vault with the contralateral leg.
Canadian Hip
Hip Flexion Bias System
Littig Hip Strut
Which Hip Joint Mechanism is described below? As weight passes over the prosthesis during stance the coiled spring is compressed. At toe off the spring is released.
Which Hip Joint Mechanism is described below? A carbon fiber strut is fabricated to the anterior portion of the socket. Weight bearing during stance compressed the strut and as the body weight is reduced going into swing the prosthetic thigh is deflected forward. No additional pelvic motion is required.
