From my reading there are two sorts of plate, a straight one that attaches to the bone, and a hooked one that can impinge on the joint, and that's what happened to me. I could ride for an hour, two at most, but any more than that was really painful. So the plate more or less had the come out, and I got the elbow plate done at the same time.
Meds are dulling the pain. But no clue how I will sleep tonight.
