As the others have pointed out in that thread, none of your sources are relevant. Minor complications don't mean much, it's only the serious ones that matter.
Even if the prices were the same, I'd still choose external mainly because I prefer the low-invasiveness of externals compared to the shudder-inducing brutality of not one but two major surgeries for internals.
As for the reputable doctors, I believe we have different standards for what qualifies as good doctors. Like I wouldn't do this surgery in India with Dr. Parihar or with an unknown doctor like Dr. Kucukkaya or with a surgeon who has killed a patient like Dr. Giotikas.
You have no sources or evidence to back up your claims that externals are objectively better. Nor did they. Saying "Erm, well actually I don't like your sources" isn't valid.
Show proof.
But you, like them, can't. Show me a single statement from
any orthopedic surgeon that externals are safer than internals. I'm not even asking for a study. Give me somebody. Can you even find a PA or nurse that holds that view? Does any medical professional? I haven't seen a single one.
You don't have the $ for internals. Don't lie. It's OK you don't have the funds. If your height dysphoria is that bad and causes you that much pain, but you don't have the money, then I understand doing externals even with their risk profile. Height dysphoria can be debilitating. Doing anything to increase you height might be worth it to some individuals, and might be worth the risks. I won't argue against that.
You are trying to justify your bad decisions to make yourself feel better. That's a common thing humans do. I get it. But your coping. Your coping over the fact that you cannot afford an internal nail, so now you are ranting on this forum to make yourself feel better.
I don't want to see more people get butchered. There's nothing in it for me. I simply want to help people. Seeing internet strangers give bad advice to people who don't know any better is bad. There are real life implications of posting on this forum.
