The orthopedic specialist I went to advised that the hardware and rod may be removed after a year from initial surgery. It's an out-patient procedure which will leave me on crutches for about a week. I'm going to have the surgery as soon as I'm allowed, but until then I have to build up my muscles and build up fat so that leg won't experience as much atrophy as it did after the accident. It's amazing, there was nearly no muscle or fat left in the leg after six days in the hospital, in a cast.
Whether the screws are actually moving or just causing pain from their location, I don't know. In any case I'm going to hold that 37mm Ti rod in my hand one day. Perhaps I'll melt it down and make a bike part out of it
