Residual Limb And Prosthesis Management Flashcards
Interface between the RL and the prosthesis
Socket
Generally, these areas are the most tolerant to pressure in a prosthesis
Muscle (as opposed to bone)
Most common socket design for transfemoral prosthesis
Ischial containment socket
Most common socket design for transtibial prosthesis
total surface bearing or patellar tendon-bearing socket
Functions of gel liners
- Cushing the limb
- Hosting a suspension mechanism (i.e. pin or lanyard)
- Maintaining suspension through negative pressure
These can be applied underneath the liner directly on the skin to relieve irritation when using a prosthesis
Gel sheath
Can be used to accommodate for space in the prosthetic socket.
Generally made of foam, plastic
Can improve fit of prosthesis
Insert
These accommodate for decreased residual limb volume and are used to maintain a congruent and comfortable fit
Socks
When should the prosthetist be notified for recasting? (Sock ply)
In excess of 12-15 ply
Initial wear schedule for prosthesis
Start at 1 hr per day: 30 mins spent ambulating
Inspect for skin breakdown
Add 1 hr each day with 50% time rest:use
When should shrinkers be worn? Why?
During the day while not wearing prosthesis
Important for fit and shaping of the RL
Pre-prosthetic phase
Lasts approximately 6 weeks
- limb protection
- contracture prevention
- single limb mobility skills
When can a patient begin wearing a shrinker?
When sutures are removed
Medicare supports a new prosthesis every ___ years
5
Bundle of nerve endings that group together and can produce pain due to scar tissue, pressure from the prosthesis, or tension in the RL
Neuroma
