Thanks for all the compliments on him everyone. I won't tell him because he's conceited enough already :-P.
BB - I think everyones covered it nicely, but I would emphasize TAKE THE TIME YOU NEED TO HEAL and FOLLOW YOUR DRs ORDERS. I had a fall that landed me in the hospital a few years ago. It was XC and put me off jumping for a very long time. I then took a break while at uni/year abroad so for nearly 4 years. I am just now getting back into jumping, though I have had a lot of fun on the flat. I spent one summer working at a guest ranch and took a course of polo lessons at uni, though spent most of that 4 years out of the saddle. I found Jane Savoie's books on fear are also useful.
When you do get cleared to ride, don't pressure yourself at all and maybe think outside the box. You can have a lot of fun learning something new, as I discovered.
