For anyone in consolidating phase or someone finished with this process, does your lengthening height actually reflect your real world height?
If you lengthened 7.5cm let’s say femurs or 5cm tibia, did you ACTUALLY measure 3’ taller or 2’ taller in reality? Or was it a somewhat/slightly shorter number by any chance?
I am booking to have external tibia with Solomin/kulesh done about 2 months from now, if anyone can please give me advice / their feedback it would be deeply appreciated. They seem like experienced decent doctors on this forum but if anyone has additional insight pls PM/comment.

Femur is tilted so femur will never be the exact amount. Slightly less.
Tibia should be straight so it should be really close to exact amount.
This is assuming you have a doctor who can competently read x-rays and measure accurately. There is a magnification factor on x-rays so you need something to compare with like a coin or something to get accurate measurement, the x-ray ruler is not inherently accurate.

By slightly less, do you mean like 5-10%? Or more
-
if the bone is lengthened 5cm then the height increase is 5cm - not sure what you are questioning??

For femurs is something like 0,5-1% less than distraction.

I was curious as to whether this actually reflected accurately in real life

Oh that’s nothing the lol, I was just thinking because bones are not 100% straight and slightly tilted how much discrepancy would be in the xray amount and actual height

Yes it's true they are not straight but the loss is less than it appears. You can draw a triangle in the femur and calculate every lenght to realize that the difference between mechanical and anatomical axis is not considerable. To tell the truth even during the osteotomy and nail insertion there's most likely a little femur lenght loss.
-
Is that true? I honestly thought that the osteotomy would give you like 1-2 mm more
-
An osteotomy inevitably lead to a minimun bone loss, and you have to add the alignment that is just theoretically perfect, so it leads a minimun loss in the main axis.
But these are just bullsh, irrelevant consideration, these losses are not palpable nor interesting.
The "osteotomy" gives you some mm only because the doc at the end lenghten the nail such as you could do by yourself at home with the machine, it's not the ostetomy itself.

Dr. Paley has talked of this: essentially the axial deviation conundrum because the femur is at a slight angle (also known as the "q" angle).
But he says it is negligible and avoidable and at most some can lose up to 1mm per cm lengthened. So 8mm total deviation from 8cm but then if you were to use Pythagorean theorem you would find the actual lengthened amount to be very, very close to the max of 8cm but not quite.
In other words, it's nothing to even worry about and any loss is negligible.

People need to stop being neurotic over a few mm anyways.
Remember in real life you won't even notice a few mm difference, it truly is negligible

Agreed. No need to replace 1 dysphoria with another.
