Hip, Knee, and Ankle Disarticulation Flashcards
What is key with disarticulations
Distal end bearing
How is hip casting done
In standing and you use wood and foam to provide a counter balance
True or False:
A total contact suction socket is not often seen with a hip disarticulation
True
Why is a total contact suction socket not seen often with a hip disarticulation (2)
- It is hard to do
2. During the swing phase of gait the prosthesis wants to pull off of the body
What is a benefit of hip disarticulation flexible silicone socket
Componentry is able to be lined up properly like a normal leg is
How does a patient with a hip disarticulation ambulate
By sitting down into the socket to get knee flexion needed for walking
True or False:
99% of the time hip disarticulation prostheses will be endoskeletal
True
What are issues with the prosthesis of a patient with a hip disarticulation (4)
- Prosthetic foot
- Alignment
- Weight
- Cosmesis
What is a translumbar amputation
From the waist down is removed
Do knee disarticulation prostheses have a quadrilateral or ischial containment socket
Nope
What don’t knee disarticulation prostheses not have a quadrilateral or ischial containment socket
Due to the longer residual limb and being able to grab lots of the thigh for fitting
What does not having a quadrilateral or ischial containment socket afford the patient
There is nothing in the groin area
What type of knee joint do the prosthetics for knee disarticulations have
Polycentric knee that collapse right below prosthesis
Does someone with a syme’s amputation have the ability to do distal end weight bearing
True
What type of socket does a person with a syme’s amputation receive (3)
- Canadian style posterior opening
- Socket VAPC medial opening
- Expandable wall socket
True or False:
With a syme’s amputation the distal circumference is much larger than proximal circumference
True
Why is the distal circumference of the syme’s amputation larger than proximal
Due to the malleoli
True or False:
The expandable wall socket is hard to make
True
How does the expandable wall socket work
Residual limb is placed in socket and then the bladder is inflated holding limb in place
What are the issues with a syme’s amputation (3)
- Prosthetic foot
- Alignment
- Cosmesis
True or False:
For partial foot amputations a rocker sole is commonly used
True
What are modifications that can be made to the shoe for a patient with a partial foot amputation (6)
- Extra depth
- Soft upper (soft top)
- Length (half inch longer than longest toe
- Firm heel counter (so back doesn’t crush)
- Heel low and broad (provides stability)
- Insole should be resilient
