Just packing and found this neoprene stretchy thing my physio gave me last year to try and stop my little finger from doing a wander down to the sea without its siblings. It is a splint of a kind. Don't know if it works because I only just found it buried at the bottom of an old handbag! I guess any strong stretchy fabric might work but alternatively you could ask your physio or OT for one. I've been wearing mine for an hour now and its making my pinky knuckle ache - Greta Garbo wants to escape!
