Week 1 Session 1 - PPT: Orthopedics & Orthotics Flashcards
What is the concept of dual obliquity applied to orthosis fabrication?
Metacarpal heads are higher on the radial side and lower on the ulnar side.
This figure indicates:
Arches of the hand must be supported in orthosis fabrication.
Which of these bony prominences is the most common pressure point?
The ulnar styloid.
Label the following creases:
A. digital crease
B. distal palmar crease
C. proximal palmar crease
D. thenar crease
E. wrist crease
Label the following position:
Safe position/intrinsic plus; it involves wrist extension, MCP flexion, IP extension and thumb opposition.
What kind of orthosis lever is this?
Class 1 lever system
Label this position of the hand.
Functional position; slight wrist extension, slight MCP and IP flexion, thumb in palmar abduction/opposition
Label the type of orthosis in the picture.
Resting orthosis
Label the type of orthosis in the picture.
Hand-based thumb orthosis
Label the type of orthosis in the picture.
Dorsal wrist orthosis
What are the steps for making a resting orthosis?
- Pattern making: makes it specific/unique to the person.
- Fitting the pattern on the patient.
- Score the pattern on thermoplastic material
- Heat the thermoplastic material and cut out the pattern.
- Heat the thermoplastic material again and mold to the patient’s hand.
- Trim the orthosis to improve the fit.
- Heat velcro hook to attach to orthosis.
- Fit completed orthosis on patient!
