Fabrication of Orthoses Flashcards
what does a well-designed orthoses pattern lead to?
a well fitting orthosis
what does an orthoses pattern provide?
two-dimensional guide
what material should you use to make a pattern?
any type of paper (Kleenex and paper towel will work)
where must the pattern extend beyond to form a shallow trough with adequate support
beyond lateral borders of hand and forearm
why do we cut out the pattern from the patient and place it on the client?
to ensure it does not block joints
unnecessarily
how do we heat thermoplastic material?
- Electric fry pans (with liner)
- Orthosis pans
- Hydrocollators (hot packs)
what is the recommended temperature?
150-160 degrees F for most materials
how long is the heating time?
ranges 5 secs - 60 secs
what is the working time?
depends on material/thickness
what are heat guns recommended for?
only only for spot heating, minor
adjustments, edge finishing or heating adhesive on Velcro
what can padding do?
- Can enhance wearing tolerance of the Orthosis
- Allow for extra space at design and
moulding phases to contour over a bony prominence, avoiding additional pressure
what are orthoses considerations for paediatrics?
age
compliance
ability to communicate (e.g. pain,
irritation)
short lever arms (decreased Mech advantage)
sensitive skin
what are orthoses considerations for older adults?
cognitive functioning
ability to don/doff effectively
sensitive/thin skin
bony areas
how long should the client initially wear the orthosis for to determine fit and comfortability?
20 minutes and then remove it to check for redness or discoloration of the skin e.g. skin irritation or vascular compromise
