text: I have a spur on the joint of my thumb nearest to the palm and the thumb is a trigger thumb as well. The brace doesn't completely immobilize my whole thumb as I would like it to. I had to roll up some gauze and put it on the inside of the palm side of the brace that runs just on the edge of the brace from the wrist up towards the mid-thumb to fill a gap and help immobilize better. I'm contemplating on buying another one that goes around the lower part of my palm instead of just my wrist.
