In reply to haworthjim: Hi Jim,
I broke mine and the Pisiform at the same time. Quite badly. I had mine in plaster for 10 weeks. I continued climbing quite a lot with my cast on and also squeezed a rubber ball all the time.
I took the cast off myself after 10 weeks as I had to work, so I used a support-brace with a metal rod insert for around another 4 weeks on and off.
The worst point was the first week with the cast off. Arm was very weak. It got a lot better very quickly.
Now, 8 years on, my wrist is 98% fine. I have full movement, and only feel it in exceptionally strange twisting undercut moves.
It took 2 years to get to around 95% strength/movement.
That's not advice, just a run down of my experience.
Good luck.
Thanks,
Jack
