I've talked to two people on getting the screws and plates removed, and the recovery time is much faster than the actual surgery, just a few weeks for the majority of the swelling to go down. However, they still have to make the same incision points to remove them, so they may be cutting over old scar tissue or tissue that has become thicker.
I guess the question I'm asking myself is, did this doctor make any effort to reach out to you? Maybe there was something sent. I hope you can find someone that worked there, look them up under Facebook, or Linkin, or google search the front receptionist name.
There is a guy on YouTube by the name RNK, he does a lot of urban exploration, he's been in multiple hospital settings where the doctors left mountains and mountains of file cabinets with patients records in them, look him up. I think a proper disposal of records is appropriate in these circumstances, who knows what they did with your records, or if they certified them as destroyed and shredded. I worked for a medical company once under contract, so I know the shredding services they contract out.
