In a patient with a normal study, surgery has really no place. Normal pictures don’t get operated on. Very important principle. Sometimes patients in their frustration will want to have something done, just do something, but it’s about the same as saying, well, you know, I couldn’t get this watch to run, so I’m going to go out in the garage and I’m going to get my hammer and chisel and we’ll see if doesn’t help. It doesn’t make much sense. The right surgery for the right problem, results in good outcomes. The wrong surgery for a particular problem when it’s wrong, very, very unlikely to help people.
