In my case they put a pin in the tibia from the knee down, and attached a plate to the side of fibia.
3-4 weeks after the stitches were out I went diving!
The leg was weight limited to around 50lbs so it was kind of complicated but:
Put the drysuit on and walked into the water with crutches.
Buddies put my smallest set of doubles (double 7L tanks) on me and a fin and then we went diving (in my case with only 1 fin, and a rich nitrox).
Around a 100 minutes later the dive was over and I shed the doubles and fin in chest deep water, and with help, crutchs and a bit of time made it back to the car, whre friends helped me get out of the drysuit.
With the exception of the week I spent in the hospital due to my bone infection, I was doing at least 1 baby dive every week untill I was really able to dive, but with very long O2 decompression from non deco dives (Hyperbaric O2 is a treatment when bones don't otherwise heal quickly enough).
If at all possible, mobilize some friends, and do something similar.
Your peace of mind will say thankyou and you need a **** eating grin after all that.
