UE Prosthesis From The That One Guy Flashcards
75% of amputations in adults are caused by _____
Trauma
Who will typically be more skilled with their UE prosthesis, a unilateral or a bilateral user
Bilateral user
a unilateral user primary uses it as an AD
What is the preferred level of below and above elbow amputation
90-100% of humerus or radius/ulna remaining
disarticulation is best!
A below elbow amputation is also called
Trans radial
What are the choices for an UE amputation pt
No prosthesis
Passive function/ cosmetic
body powered/ conventional
myoelectric/external power
hybrid
adaptive
What are the advantages of a cosmetic or passive function prosthetic
Cosmetic
Light weight
Simple
Low maintenance
Inexpensive
Great for partial hands
Provides opposition
what are the disadvantages of a cosmetic UE prosthetic
no active prehension
limited function
decreased durability
unreal expectations for cosmesis
custom silicone very expensive
a body powered prosthetic is driven by what kind of system
Harness system
driven by scapular abduction, chest expansion, shoulder depression or other shoulder movements
Advantages of a body powered prosthetic
Heavy duty construction
proprioception
less expensive
light
maintenance
Disadvantages of a body powered prosthetic
Grip force limited
FUnctional ROM limited
harness can be restrictive and uncomfortable
poor cosmetics
possible over use or nerve entrapment
How does a double control harness work?
One harness strap controls each movement
one for the terminal device (hand) and one for the elbow
The most common kind of body driven orthotic has what kind of terminal device
Voluntary opening - it stays closed unless you act on it
this makes it easier to grip things with
What are the advantages of a myoelectric/external power prosthetic
greater function
increased cosmesis
greater grip force
reduced or elimiated harness
Disadvantage of myoelectric/ external power prosthesis
increased cost
weight
environmental interference
Hybrid prosthesis advantages
Greater functional envelope
Reduced weight
Greater grip force
Reduced harness system
Feedback of forearm flexion velocity
Reduced initial maintenance and costs
Hybrid prosthesis disadvantages
increased weight on harness
control harness required
What is an adaptive prosthesis
customized for specific activity
What is contraindicated for Osteo-integration patients
Swimming in water
doing anything that will get the site dirty
High intensity physical activity
osteo-integration is mainly for what kind of pts
pts with a hard to fit residual limb
What kind of osteo-integration procedure is FDA approved
Screw Fixation
Note: Pt must fail having a normal prosthetic first to qualify for this through insurance
