In reply to MischaHY:
I'm the proud owner of a (non-climbing related) TFCC tear. Having decided surgery, I've found two things really helpful:
1) Rice bucket training:
2) Taping while climbing: start by looking at and then play around till you get something that works. I've found that I use elastoplast to block out some range of motion in ulnar deviation helps a lot. I know that there are some particular types of hold that I find tweaky, and if a route starts to cause an ache I play it cautious and come back another day.
