Sorry to hear about your injury, and best wishes for a steady and full recovery!
My suergon had no interest in X ray or MRI before or after, and said once he got in there he would know what was going on, and before he got out of there he would know how well it was fixed. He said once they suture the tendons down, they actually test the thing my manually moving it. If need be, he said he would use some wire to hold it down, and this would be removed later. I woke up 2 hours fifteen minutes later, and all was good. My scars are exactly 4".
It sounds like the surgeon did what he neeeded to do, and only he can answer your questions about what was done. My suregeon sure seemed to be done with me after surgery, and didn't offer much explanation. (He has warmed up in the 3 visits since) Your caregivers may simply not know how to answer your questions, and perhaps your PT can act as your advocate, and arrange for the surgeon to come down the hall and meet as a team.
Regarding your question on medical care in the states, we are at present undergoing an emotional national debate on health care reform. I wouldn't touch that question with a ten foot pole.
Hope you keep working through it and good luck!
