In reply to SteveJC94:
I've managed a couple of wrist fractures in my life, and can only advise that they take time. Last one I had was a Smith's fracture, which is what you describe with some anterior displacement, which was fixed with pins which were removed. I had a backslap for a week following the surgery, then into a splint as you describe. By the sounds of things, a bit more complex than your non-displaced fracture, but anyway:
It took me quite a while to regain full strength in the wrist, and it still can be a little weak on undercuts 7 years later (apparently characteristic for that position and a Smith's fracture, so maybe less relevant). Following the removal of the pins (6 weeks post repair) I was back climbing easy stuff in three weeks, and probably took me about 6 months post injury to get back to full speed. My main advice would be a) do your physio b) do your physio and c) do your physio, as the joint will be pretty stiff following a period of issue. And go easy on your return to climbing - stick indoors, stick to boulder/top rope and slowly build up the load and steepness of the angles you climb on. You'll know by feel when you are ready to make things more difficult.
