Batman's Medical Records

As I recall, Bruce's injuries from Bane breaking his back were explained by a car accident, at least in the Knightfall novelization. Also in that novel, the doctor treating him noted how incongruous his injuries were with the "dangerous games" of his "youth" he claimed as the cause. The implication is that he simply doesn't go to the hospital very often.

I'm not sure why he wouldn't use several of the actual explanations as an excuse. Gotham is well known to have several criminals wielding dangerous chemicals running around. He could plausibly claim he got hit by some Fear Gas, then deny any requests for blood drawing. Everyone assumes he's on something besides Fear Gas, when he really doesn't want them to find evidence of exposure to other toxins and chemicals. There are legal measures, I presume, but he can afford the best lawyers in the world.

As for psychology, he has a ton of psychological experience, and could probably find a way to stick to his "profile" as Bruce Wayne, assuming he didn't already have it determined ahead of time.

I mean, half the article's premise is that Batman is unable to come up with plausible explanations, or doesn't have ones ready. Batman.

The locusts will swarm the studio and systematically devour the sets, the backdrops, the desk and the seat cushions, while the hosts..."
