A little recovery news...
I had my first follow up with the surgeon this week. Now that the surgical pain is done, it is time to start working on passive range of motion. Just some gentle stretches several times a day trying to restore range of motion to work out stiffness and make sure I don't end up with troublesome surgical adhesions.
Out of curiosity, I picked up the couch bass and put it on my lap this afternon. Not much I can do yet - fretting is as much/more a shoulder action as a forearm/hand thing. And external rotation is still limited, so reaching the 7th fret is a stretch too much. In time I'll get there, but I will have to try regularly to see where I am.

And I am still typing one handed. So, please read everything I post slowly.
