Ooooh... that is a nightmare scenario. Sorry to hear it BUT I will leave you with this...
 
One of the most talented guitar/strings players I know (seriously anything with strings on it he can rip out on... and I don't mean metal crap, he's a traditional teacher) had hist entire left wrist and part of his hand totally shattered and filled with pins in his twenties. They said he would never play again.
 
Boy were they wrong.
 
And as far as the osteoperosis... that is going to be an issue as the bones knit for sure but you just gotta crank up the calcium and vitd intake (magnesium and potassium probably as well). I'm sure this has been mentioned already by the docs but if not look into it.
 
Of course you should be being cared for by speciliasts who deal with musician's injuries and rehab as well. Since it is your career at stake and IIRC you are in England you should be able to get it covered by insurance... and if not spend the extra dough or hunt around for a sympathetic rehab place to take your case.
 
Best of luck to you. I truly do feel for ya. That... freaking... BLOWS!
 
It is good chance to dig down into the theoretical. There is always more we can learn mentally even when our hands/bodies are fuxxored.
 
Cheers!

I really wish you all the best in your recovery. It's tough when things go south, been there man. On the plus side it's winter, the perfect season to be laid up. They can do some amazing things with newer tech and rehab options.
 
Keep us up to date. As Bit said, we're all rooting for you.

Thanks, Beeps.  I already receive a lot of treatment for the osteoporosis.  I have had yearly bisphosphonate infusions, but am currently enjoying a "drug holiday" - I love that term, it sounds so much more fun than the reality. I am also constantly on Calcium and Vitamin D supplements.
 
I can't seem to face music at all at the moment. My studio has never been so neglected.  I had many plans for when I was forced into not playing, but can't seem to face being in here at the moment.
 
I have planned to start back at work on Wednesday, so need to start preparing lessons, but seem to keep putting it off.
 
Thanks again or your kind words and support.

Thanks, John.
 
I have been kept busy over the festive season with my family - a 7 year old and a 18 month old, which has been lovely, but frustrating - not being able to build the toys Santa brought, or play with them as much etc.
 
I am pinning my hopes on some good news on Tuesday, but think I am fooling myself.
 
Thanks so much for your king wishes, and Happy New Year to you all.

I worked with a guitar player a while back who became a good friend. He has played with 801, Andy MacKay, Brian Eno, supported King Crimson and far too many to mention.
 
He damaged his right arm at one point - think i was out of action for a year+.
 
He now has one of the most remarkable Left Hand legato/Hammer-On/Pull-Off techniques that I have ever seen. Utterly astounding.

I echo all here that want to see you back here in great health. You've been through some tough times but we are all pulling for you. Do what your Doctor says and don't be impatient. Even when you feel better don't push yourself. Time is what is needed, take it.   

Following my m/c accident a year and a half ago, my right thumb was fractured and dislocated (bottom joint, where it joins the hand).  It was pinned into a more fixed 'pinch' position (thumb-index finger pinch).  It was still not in the right position so they operated on it again and this time double-pinned.  It was still not in the right position (bodies are harder to fix than cars), and I've lost most of the movement in that joint.  However, due to the position it was fixed in, I can still hold a plectrum perfectly well, perhaps even better than before.  This would have been a problem if, for example, I played slap bass, but for finger picking or plectrum picking it's perfectly fine.  Hitch-hiking is off the table though (unless I use my left hand).  Which joint is causing you problems?

@John - Thanks, John.

They have fused the metacarpal phalangeal joint of my right thumb, so it sounds like the same one.  They were setting it into a fixed 'pinch' position so that I could still hold a pick and fingerpick (I trained as a classical guitarist originally).
 
It will mean I lose some of the reach of my right hand on the piano, which is a pain, but luckily I have quite big hands so should still manage octaves, hopefully. Gone are the days of playing tenths..
 
Slap bass had not occurred to me.  I do teach bass, so that may be an issue.  I am reminded of the line in Mike Senior's book (I think) - the best mixing strategy for slap bass is the mute button.. 

I hope all is going well at this point ... best wishes for full recovery.

tbh, I couldn't play slap bass before, so not a huge loss for me ;-)
 
I guess if you can slap using the wrist only (rather than relying on free movement of the thumb), then things should be OK.
 
Best wishes for your recovery!  I may need to have mine fused at a later time, similar to you, depends on how vigorous the onset of early arthritis is in that joint.
 
p.s. on the subject of guitarists coming back from injury, check out Julian Bream's recovery from his car accident.  Quite remarkable.
