Have done both my wrists (though not at the same time thankfully). The first time was a clean break and it is 100%. The second one I really smashed up and have got less than 50% movement back after 2 years. It’s also still very painful when using it in certain ways (e.g. it’s very painful when pushing down on on long and steep descents but fine when pulling up like lifting a heavy suitcase).
My advice would be to take it slow and make sure you do all the physio exercises as often as you can. Don’t worry about the lack of movement or strength at the moment, as it will (hopefully) come back over the next few weeks/months.
In both my cases it was several months before I could ride again. You may also need to get over any fear you have when back on the bike. It took me a long time to get over it the first time but I was prepared the 2nd time. Good luck.
