Any OTs on line please who can tell me what this strap might be called?

[Happytodayhappytomorrow]

I had an appointment today with an OT at the hand clinic and she was tossing up between giving me the medium size strap or the small. She left it to me to choose and I chose the medium but with hindsight, I think I should have chosen the small. (My hands were perhaps swollen due to the heat of the tube journey and the heat in the hospital). I’m looking online to order myself the same thing in small but I’m struggling to find the exact same thing. The strap that goes around the outside of the thumb is apparently the important bit.

Any tips gratefully received.

TIA

Oops

It could be a thumb spica or a wrist and thumb splint or thumb stabiliser. I can't tell how long it is to be sure. Could you show me the full splint end to end? Is it for your CMC joint?

Oh to clarify I'm an OT by trade, use to work in orthopaedics but it was a good few years ago now!

Also you could you call the OT and ask them to pop the small one in the post to you

Thank you mummyoply
I don’t remember the OT’s name so I might struggle to track her down at the hospital.
Hopefully these two photos show it better?
