I have not had the surgery but I have helped do them many times. I have done a lot of Ortho during my time in the O.R. I take it your fracuture is stable and there is no compromised blood supply or nerve damage. If you are having plates and screws you should be okay. They have special plates these days with a clover leaf shape to fit these areas. As I said if the only issue is the fracture and no vascular, nerve or tendon damage the recovery should be okay. The problem is sometimes if the fracture is through the head you could develop arthritis in the joint. These fractures can be distal to the head and that is a little better. Either way when you deal with a joint in your body you can always have problems. If that head is not shattered it is very unlikely they would relace the head. I wish you luck. This is not medical advice just giving my input based on my experience assisting in these cases.
