lower extremity amp Flashcards
K0
does not have the ability to or potentially amb or to transfer safely without assistance
a pro does not enhance their QoL or mobility
K1
have the ability of the potential to amb or transfer using a pro in level surface of fixed cadence
normally limited or unlimited household amb
K2
has the ability of the potential for amb
transverse low level barriers such as curbs, stairs, or uneven surfaces
limited community amb
K3
has the ability of the potential for variable cadence amb
community amb
can transverse most environmental barriers
may have a vocation, therapeutic, or exercise activity that demand pro use beyound normal means
K4
has the ability of the potential for prosthetic amb that exceeds basic amb skills, exhibiting high impact, stress, and energy levels
child, active adult, or athlete
what are the pressure tolerate areas on the trans tib pro
patellar tendon
pre tib muscle
lateral aspect of fib
medial tib
popliteal fossa
pressure sensitive ares of the trans tib
tib condyles
fibular head
distal fib
tib tubercle crest
distal tib
hamstring tendon
what is the suspension
o This is the part of the prothesis that prevent it from falling off as you move
o Gel liner
what is a blocking gel liner
have a pin in the bottom that prevents the pro from falling of
what is the socket
o This is the part of the pro that your res limb slides into
what is the shank
the part that connets the socket to the foot
what is the aligments
the spacial relationship between the socket and pin
what are Sheaths
worn next to the skin to minimize
- shearing forces
- sweat
- aid in skin integrity
- or may be worn between liner and the pro to help with donning
what are liner liners
worn against the skin and act as a sweat absorption aid under a gel liner.
what are the two types of liners
gel and foam
what is the point of liners
Liners are worn between the leg and the socket.
They provide protection and comfort for the residual limb and can sometimes also assist with suspension.
how often do we clean liners
every evening
Wash with lukewarm water and mild, odorless soap
turn right side out to dry overnight
what are the two typed of sockets
patella tendon bearing
total surface bearing
patella tendon bearing where is the pressure
Counter-pressure of the patellar tendon bar and posterior popliteal region
total weight bearing socket where is the pressure
uniform distribution without significant accommodations for pressure
what do we use socks for
used to accommodate changes in size of the residual limb
what can wrinkles in socks leas to
can cause unwanted skin issues and wounds
Too many socks can cause
Feeling of a long prosthetic limb
Sensation of hill climbing
“Hammocking” (when socks prevent residual limb from fitting snugly in prosthesis with the residual space resembling a hammock) may cause distal discomfort
Pressure on tibial tubercle
Difficulty donning
Too few socks can result in
Short prosthetic limb
Sensation of dropping into a hole
Excessive pistoning
Distal pressure
Pressure on distal patella
Pressure on distal fibula, fibular head or medial tibial flare
Easy donning
what is a Quadrilateral socket used for
trans femoral
opposing forces to keep the ischial tuberosity on a ledge that is built into the socket
what is the main WB in a Quadrilateral socket
the ischial tuberosity
what is ischial containment socket used for
force is focused primarily through the medial aspect of the ischium and the ischial ramus
socket encompasses both the ischial tuberosity and the ramus; the specific contour depends on the musculature, soft tissue, and skeletal structure of the amputee.
Sub-ischial brimless sockets
vacuum suspension system and gel liners to ensure constant contact with the socket to minimize movement, maximize femoral control, while lowering trim lines
what is one thing true about all trans femoral sockts
These sockets use the entire residual limb to evenly distribute weight bearing forces.
