Question 1

What is the concept of dual obliquity applied to orthosis fabrication?

Answer 1

Answer 3

The ulnar styloid.

Question 4

Label the following creases:

Answer 4

A. digital crease
B. distal palmar crease
C. proximal palmar crease
D. thenar crease
E. wrist crease

Question 5

Label the following position:

Answer 5

Safe position/intrinsic plus; it involves wrist extension, MCP flexion, IP extension and thumb opposition.

Question 6

What kind of orthosis lever is this?

Answer 6

Class 1 lever system

Question 7

Label this position of the hand.

Answer 7

Functional position; slight wrist extension, slight MCP and IP flexion, thumb in palmar abduction/opposition

Question 8

Label the type of orthosis in the picture.

Answer 8

Resting orthosis

Question 9

Label the type of orthosis in the picture.

Answer 9

Hand-based thumb orthosis

Question 10

Label the type of orthosis in the picture.

Answer 10

Dorsal wrist orthosis

Question 11

What are the steps for making a resting orthosis?

Answer 11

1. Pattern making: makes it specific/unique to the person.
2. Fitting the pattern on the patient.
3. Score the pattern on thermoplastic material
4. Heat the thermoplastic material and cut out the pattern.
5. Heat the thermoplastic material again and mold to the patient’s hand.
6. Trim the orthosis to improve the fit.
7. Heat velcro hook to attach to orthosis.
8. Fit completed orthosis on patient!
