Perhaps it's most likely the nature of the break in that something was needed to pull and hold the irregularly fractured bones together forcefully so that they fuze together. In any case only physicians with specific injury X-Ray and other data , not us football message board folks, understand the tradeoffs.
I think you hit the nail on the head, PWP.
It seems that the plate was always needed for the healing process, due to the nature of the break and the specific bone(s) that were at risk.
Many here have said that the plate was put in so that "he'd be ready for the playoffs," but I think that the 6-8 week timeframe for healing was going to put him in line to probably play in the playoffs anyway. The insertion of the plate is most likely due to the nature of the injury.
It was known back then that they'd need to operate again? Yes, but wasn't that just to "remove" the plate and it was to be AFTER the season?
Was it known 4 months ago that they'd need to operate now? And then operate AGAIN after the season (if all goes well) to remove THE NEW plate (put in in the 4th operation)?
It's a little confusing.
I agree that it's a little confusing, kennyb.
From what I understand, you are right about the plate being put in with the idea that it would stay there until after the 2013 season. For one thing, it was a bigger plate that wouldn't make him as vulnerable to another break (unless it happened in the "perfect storm" setting), and it was likely put in to aid the healing due to the strange and rarer nature of the outside bone etc.
Another reason they didn't want to remove it is that any kind of surgery increases the chances at problems and infection, so you don't want to go in too many times--particularly in a small window of time like we're seeing.
So, NO...they did not plan on Gronk having to go back into surgery this May from what I understand. The surgery was planned on happening to remove the plate when the season of 2013 was completed. The infection that was discovered is the reason why they are needing to now "look around," and make sure it has cleared out and isn't spreading down throughout the bone.
If everything's okay, they'll replace the plate and everything will be fresh and ready to go. If there is still signs of an infection when they go in this time, they won't bother wasting their time/efforts in replacing the plate...that will be done with the upcoming FIFTH surgery. The only thing that will be done if they see signs of infection this time will be a thorough cleaning of the area to help to better remove that infection. The problem with having an infection is that they cannot really know until once they are in there, in terms of whether or not anything is still lingering.
