1

How much %age of forearm is kept in a very short, short and long transradial amputation?

Very short = <35%
Short = 35-55%
Long = 55-90%

2

What structure needs to be maintained in wrist disarticulation to preserve supination and pronation

Distal Radioulnar joint

3

3 levels of transhumeral amputation

1. Humeral neck = <30%
2. Short = 30-50%
Standard = 50-90%

4

What is prehension

Ability to hold or grasp something

5

What are 3 advantages of doing an elbow disarticulation instead of transhumeral?

1. No risk of bone spur or HO at the elbow disarticulation level
2. Improved prosthetic suspension
3. Allows for greater lifting, pulling, and pushing

6

In a transhumeral amputation with residual limb >35%, what 2 suspension systems are used to attach the socket?

Figure-8 OR shoulder saddle and chest strap

7

Amputation of the hand is considered if...

Irreparable damage occurs to 4/6: skin, blood, bone, nerve, flexors, extensors. It is then considered a "mangled" hand.

8

What is a forequarter amputation

Removal of arm, scapula and part of clavicle

9

Transhumeral residual limbs shorter than _____% will be fitted as a shoulder disarticulation

30%

10

When doing a transhumeral amputation, how many cm above the elbow does the amputation have to be

>6.5cm above the elbow

11

Most common level of amputation in the upper extremity

Transradial

12

What muscle do you want to preserve in a transradial amputation if you want to keep good elbow flexion?

Brachioradialis

13

A transradial residual limb length of ____% to ____% is preferred when optimal externally powered prosthetic restoration is goal

60-70%

14

If cosmesis is of importance to an amputee with a wrist disarticuation, what kind of amputation would be more appropriate?

Long, below-elbow amputation

15

For the majority of cases, what is the reason behind shoulder disarticulation or forequarter amputation?

Malignancy
