Parker's surgeon just called. She had no difficulty removing the plate from his leg and she got the fatty cyst out of his neck without complications. She also identified the screw that had hidden the infection from his immune system and has sent it in for culture, but she suspects it's a run-of-the-mill bacterium that, absent the screw, his body would barely have noticed.
He'll be a little wobbly for a day or so and he'll have to wear his cone for two weeks, but the surgery wasn't nearly as invasive as the original repair. So, he's expected to make a full and speedy recovery before the end of the month. I'll pick him up tomorrow morning and post photos of his new haircut shortly after.
