Wow, sounds pretty serious. Hopefully after it heals you won't have lingering pain around your hip.
Sounds a lot like something I did the other day, but I was going from grass back to the MUP on my road bike. Didn't take it a 90 deg angle and my front wheel fell into the gap and I started to go over sideways. I was also cleated in but I ripped my foot out and broke the metal clip on the pedal, so I was able to catch myself with that foot...and after hearing your results, thank goodness I did.
Again, hope all goes well and certainly hope you don't end up needing another surgery.
