Yah that’s what I watched too :| idc if he says the nail is full weight bearing, something is bound to go wrong. No doctor with credibility should approve this for patient safety.

May I ask, how do you know something is bound to go wrong? I sense fearmongering here. It was his decision to lenghten a certain amount and if he has any complications, he has to deal with them himself. Besides, as far as I've read, there are almost no untreatable complications.

Quote from: GrowGrow123 on September 01, 2023, 12:12:48 AMNo, I think he is right. He was referring to the plane seat and not being literal.

I did some sleuthing. Here goes.

On March 23, he says his femurs are 45cm and his tibias are 37cm. On April 16, he says he has reached 172 cm in length after 7cm lengthening from his original 165cm. So we can estimate that in the month that passed he gained roughly 3 cm. Which means on March 23, he had only lengthened about 4cm.

That means his original femurs are 41 cm and his tibias are 37 cm.

So, no, his femurs aren’t literally shorter than his tibias. I would also be willing to bet that he’s underestimating how long his femurs are. It is common for people to overestimate how long their tibias are and to underestimate how long their femurs are due to the head of the femurs being above the trachonter landmark on the hips.

He himself, in his diary, mentions not being super sure how to measure his tibias and femurs. So it is very likely he made the measuring mistakes most people make. I would guess his original tibia to femur ratio is between 0.83 - 0.90. Longer than most people’s ratio, yes, but nowhere near “femurs shorter than tibia” as you suggested.

His original height was 161.3cm if you click on his diary it’s literally the first thing at the top. Not sure where you pulled 165cm from but I’m sure that means all your other calculations are totally off.

because you need to consolidate 12+ cm of bone which is incredibly difficult to do. You’re walking effectively on a singular, very long nail and minimal callus that could definitely give way and bend. I linked earlier a thread where the validity of full weight bearing on betzbone was heavily questioned. Also did you see him walking? it looks horrible aesthetically at such a dramatic length with shorter tibias - I’ve seen others go toward 9cm and even that was seriously pushing the limit. The complications get exponentially worse when you lengthen that much. I’ll happily eat my words if I see no nail bend on x rays and full consolidation in a year.

“ In spite of the extensive experience of the treating surgeon, many soft tissue and bone problems are possibly expected. Safety of the patient has to be more important than gaining more length [42]. For example, if a weak regeneration zone develops, which is not responsive to cycles of compression distraction, the surgeon has to reduce the expected area of lengthening by gradual compression to improve the regeneration and avoid nonunion. In our opinion we think that this procedure has to be undertaken by a surgeon with great experience in the field to handle the potential complications”

“ We believe that optimum lengthening of the lower limbs can be done only up to 5 to 7 cm, beyond which outcome may be suboptimal in view of cosmesis (trunk-limb proportions) [4, 19], altered biomechanics, and soft tissue function [10]. ”

And yes - often the complications are treatable with procedures like bone grafting. But then let’s be blunt about those risks and additional costs upfront if we are going to start advertising 12+ cm as safe.

On March 26, he says this (quoted):

“I've now reached 7cm and I now stand at 172cm tall, and I feel tall around people who are at my old height now. I have two sisters who are a 166cm and 167cm tall, and there is a clear difference in our height - and knowing I was shorter than them that is such a weird and special feeling. And this is still wide duckass and wide-legs, so in reality I am not actually 172cm yet.”

172 - 7 = 165, right?

The larger point here is that he says a lot of things in his diary. Some contradictory. I wouldn’t take his statements at face value.

If you have a photo of him standing straight before surgery, we can lay this to rest lol.

This guy seems to be a bull ter then. I don’t know what the truth is about the whole thing. But even without any measurements, it’s apparent to anyone his legs look out of whack. Hopefully for this guy’s sake he either always wears long pants or maybe decides to do tibias.

After we stop lengthening, how many days gap should we take before frame removal surgery?

How many days should we take break, after our limb lengthening Target reached , before we remove frame?

If somebody thinks 12 cm on their femurs is safe, they need to stop spreading fake news, and tempting others to play with fire.
