AKA Prosthetic Components Flashcards
Alignment of femur in ischial containment socket
Adducted alignment of femur in the socket
Mediolateral and AP dimension of ischial containment vs. quadrilateral socket
Ischial containment is narrower mediolateral.
Quadrilateral socket is narrower anteroposterior.
Advantage of a polycentric knee
It has a mobile center of rotation that allows for stability and control
Amputees with residual femur < how much are fitted as hip disarticulation
<5cm
Which of the 5 AKA suspension systems has less medial lateral control and is less secure
Total elastic suspension belt
Where is weight bearing for a hip disarticulation prosthesis?
Ischial tuberosity

BKA use a rubber suspension sleeve.
AKA use a waterproof suspension belt.
Which of the 5 AKA suspension systems is the most secure suspension method with greatest control
Suction socket
What is the standard prosthesis used for a hip disarticulation
Canadian hip disarticulation prosthesis
Where is weight bearing concentrated in ischial containment socket?
Medial aspect of ischium and ischial ramus
2 socket designs for AKA
- Quadrilateral transfemoral socket
2. Ischial Containment Socket
Which of the 5 AKA suspension systems is used with those with volume fluctuations and has good shear control
