I have been diagnosed with non-stenosing tendovaginitis (also called trigger finger) on the 4th and 5th fingers of my right hand. The problem has been going on for 7 months now, two months ago my doctor started a treatment with a custom made splint to wear during the nigth, which holds my two fingers in a semi-bent position, but things have only got worst since then.
It's not clear to me what is the benefit of wearing a splint at night in a position that is basically the same that my fingers assume without a splint, I asked my doctor and she said that this is to avoid the contraction of the fingers that happens during the R.E.M. phase of the sleep. Does anybody know about this (specifically, what is the reasoning behind using a splint to treat trigger finger)?.
I also told my doctor that on the Mayo Clinic site I read that the splint should keep the fingers in an extended position instead of semi-bent, but she said that Mayo Clinic was wrong.
