I did a little more digging and found that Trucco had a fast recovery that even the doctors were amazed with and he was out of the hospital in just 5 days! Also, the accident happened near the beginning of that writer's strike, so he had a good amount of time to recover before filming started up again.
I still can't help but wonder, though, if it was Trucco's accident that gave the writers the idea to have Anders 'thrown in the vat' as an integral part of the storyline....
