ORTHOTICS AND PROSTH ETICS
FINAL EXAM (Q&A) ALREADY
PASSED.
Question : T/F UE Amputations is more common than
LE
Correct answer: FALSE. LE= 90-95% of amputations
UE= 5-10% of amputations
Question : What is the most common cause of UE
amputations?
Correct answer: TRAUMA 75% of UE ampations=
trauma (MVA, machinery accidents, GSW, electrical burns)
Question : Should you refer a patient with a finger
amputation to a prosthetist?
Correct answer: Yes! They do cosmetic restoration
Question : Proper terminology
Correct answer: Upper Limb, NOT "upper extremity"
Limb deficient, NOT "amputee" Residual limb, NOT "stump"
Question : Your patient is amputated at the wrist, what
level of amputation is this called?
Correct answer: Wrist Disarticulation
Question : Your patient has an amputated finger, what
level of amputation is this called?
Correct answer: Finger amputation
Question : Your patient is amputated across the carpal
bones with a full remaining wrist, what level of amputation is this called?
Correct answer: Transcarpal
Question : Your patient has full elbow, but is amputated
along the radius. What level of amputation is this called?
Correct answer: Transradial Anywhere along the radius
Question : Your patient is amputated at the elbow, what
level of amputation is this called?
Correct answer: Elbow disarticulation
Question : Your patient is amputated along the humerus,
what level of amputation is this called?
Correct answer: Transhumeral Anywhere along humerus
Question : Your patient is amputated at the shoulder,
what level of amputation is this called?
Correct answer: Interscapulothoracic Usually from
cancer
Question : Your patient has an elbow disarticulation, but
their prosethetic is too bulky with outside hinges, and too long. What is an alternative option?
Correct answer: Revision surgery They amputate further
up on the humerus, to allow for a better fitting prosethetic with better proportions. more arm does NOT equal better; no fx advantage to elbow disarticulation.
Question : Your patient had a finger amputation, and had
a prosthetic finger made. What type of prosethtic is this?
Correct answer: Passive Functional/Cosmetic
Advantages: -Lightweight -Cosmetic -Simple -Little
maitenance -Great for partial hands -Provides opposition, stabilization, and balance -Off the shelf =
inexpensive Disadvantages: -No active prehension -
Limited function -Decreased durability -Custom = expensive
Question : T/F A passive functional prosthestic allows
for active prehension.
Correct answer: FALSE. No active movement;
PASSIVE/cosmetic
Question : What are the advantages of body powered
prosthetics?
Correct answer: -Heavy duty construction -
Proprioception -Less expensive -Lighter in weight - Reduced cost of maitenance
Question : What is a big disadvantage of the body
powered prosthetic?
Correct answer: Grip force is limited by strength and
rubber band tolerance!
Question : Your patient has an battery powered
prosthetic that is controlled with the electrical signals generated naturally by muscle contraction. What type of prosthetic is this?
Correct answer: Myoelectric
Question : What's the biggest disadvantage of a
myoelectric prosthetic?
