To follow the thread of tangentially related concepts:
The Ilizarov apparatus (caution NSFL). The leg is intentionally broken, then a terrifying cage encourages it to heal in a different size or shape.
I’m not sure how much it’s used now, but I was presented with it as patient as a potential option about 20 years ago. It was kind of a “please don’t pick this one it’s clearly worse” choice. Thankfully they’d done about a decade of prep work to enable me to pick the less extreme option.
I’d be very surprised if it was to become taller. I’d have to watch the clip again, but I only recall seeing the device stretching his pants on one leg.
I know they’ll do it to fix leg length discrepancies above a certain threshold, especially if the other procedure isn’t viable. I don’t know if there’s other medical reasons to consider it.
