Q

Is scar placement during surgery important for UE amputation?

A

No, unlike LE scar placement is not critical as there is little weight bearing pressure placed on the limb and few bony concerns

Q

With a forearm UE amputation, what should we keep in mind?

A
  1. As distal as possible

2. Lose pro/supination so there is no rotation in the socket

Q

What are the important bony landmarks which much be considered when fitting the patient with a harness body-powered prosthesis?

A
  1. C7 - harness ring must sit below or it will place excessive pressure on cervical spine
  2. Clavicle - harness passes over the clavicle which may cause breakdown
  3. Acromion process - to measure length
  4. Scapula - need max mobility to assist with mechanics

Q

A hook is good for what?

A

Manual labor (very durable)

17
Q

What do UE amputees put around hand to help control tension?

A

Rubber bands

18
Q

T/F The above-elbow harness is naturally more involved than the below-elbow devide

A

True

19
Q

In the A/E harness, the anterior strap helps resist what?

A

Helps resist rotation of the unit

20
Q

In the A/E harness, the main suspension elements travel over what muscle?

A

Deltoids

21
Q

What shoulder motion operates terminal device in A/E harness?

A

Shoulder flexion

22
Q

How do you lock the elbow of an A/E harness?

A

Through depression of shoulder and humeral abduction and extension to operate terminal device

23
Q

Elbow must be what to operate terminal device?

A

Locked

24
Q

Newer arms are bionic in nature meaning what?

A

They are powered by the user through electronics

25
Q

Some arms are controlled by ____ in the residual limb while the newest arms are controlled by _____

A

Muscles

Thought processes

26
Q

Myoelectric arms are suspended through what saystems>?

A
  1. Pin and lock
  2. Suction
  3. Supracondylar
27
Q

What is targeted muscle reinnervation?

A
  • Nerves in residuum are transferred to target mm that no longer perform function
  • Augments signal to muscle for easier and enhanced prosthetic control
  • nerves grow into new target tissues and enhances control of myoelectric arm
28
Q

Targeted muscle reinnervation should only be used for what two types of amputations?

A
  1. Shoulder disarticulation

2. Transhumeral

29
Q

For osseointegration of the UE, how many surgeries will they have?

A

2 surgeries 6 months apart

30
Q

T/F Small studies report improved function and QOL for patients with osseointegration of the UE.

A

TRUE

31
Q

What are neural prosthesis interfaces?

A
  • Use functioning neural transmission pathways for direct control of robotic limbs
  • Can restore movement and touch
32
Q

neural prosthesis interfaces combine with two types of control?

A
  • Combing forward control with feedback control (something slipping from hand)
