I've been using rubber tubing to shape the thermalplastic because the plastic doesn't stick to the rubber. I tried vinyl tubing, but the that material instantly bonded to the plastic.
Then I got the "bright idea" that I could just use the soft vinyl as part of the splint. (I'm being a bit sarcastic with bright idea since it seems kind of obvious now).
I created a tool to split the vinyl tubing laterally down the center. Then added colored thermalplastic to the inside of the half-tube. Shaping was *much* easier.
Here are the results:
 |
| Splint with sample of vinyl tubing used. |
 |
| Bottom of splint. Vinyl tubing visible. |
 |
| Finished splint mounted. I think it's a little too short. |
 |
| back view |
 |
| View of side with finger arced back. (used when drying under splint) |
 |
| Side view with finger bent. No movement, but proximal side of splint should extend closer to MCP joint. |
Condition of the finger after removing splint v12
 |
| V12 was touching the skin. You can see indents where. |
