I'm very sorry to hear of your brother's accident.
I can relate, as I also broke my ankle about five years ago and had to have an operation. A small plate and six screws were used to stabilize the break. I was out of the hospital within several hours of check-in. I was off of crutches at five weeks and have made a 100% recovery with full range of motion. It is amazing what results that can be achieved with a successful operation. Today it is as if it never happened, except for just a small scar on my ankle.
John will be in my prayers for a successful operation and recovery.
