I find smug, self serving amusement in the fact that so many skilled therapists and doctors shrivel at the thought of using thermoplastic to support a joint. Whilst their trepidation works to my advantage, ultimately it helps no one. So here is a basic recipe.
|It should look similar to this too thick, poorly fitted pre-fab thing|
- Get a piece of thermoplastic, 1.6mm thick.
- Cut out a pear shaped piece, long enough to extend from just proximal to the IP joint of the thumb, to just distal to the CMC joint.
- Put the plastic in hot water just as if you were softening a mouth guard.
- When it has softened enough, place it over the dorsum of the thumb, working it into shape so that it contours well
- Trim to fit, making sure it doesn't impinge over the CMC with wrist extension and radial deviation.
- Tape on.
- Refer to a hand therapist for treatment (happy with that BC?)
Rehabilitation after that is more involved, and here's where you need to refer to an experienced hand therapist because the splint cannot be expected to do anything more than limit more damage. If you can get that at least half right, it's a start. I can always fix up your smashed up, finger dinted thermoplastic disasters afterwards and no one needs to know but us!
Look after those fingers,
