This was talked about in several other topics but i figured it deserved its own since its a very important issue.

I have heard that you can walk with fixators during lenghtening phase, as well as consolidation phase, and the fixator and pins are supposed to keep the bone in place and prevent the gap from closing from pressure during lengthening and consolidation phase.

But it seems some people have lost height mysteriously, after lengthening was done. So is it true that the gap created in the bone for height gain can actually compress if you stand up and/or walk? Are the fixators not reliable? and during consolidation phase is it still possible for the gap to compress even though you are wearing the fixator? in this phase shouldnt the bone already have formed enough callus in the gap to make it impossible to compress unless it was fractured?

It is spine compression. Deal with it.

So are you sure that the height loss isnt due to compression of the bone gap? Some comments in that other thread made me confused. I was hoping that the external fixator would be able to guarantee that the height gain was maintained. However in swedens case it must be something else like the spine i guess as he had nails inserted as well..

Hey Wannabegiant.

You only wear the external fixture during the lengthening phase. And any lost you made during your lengthening phase you can make up for. It just means you have to spend more time lengthening.

He measured his height several times when he came back home. And his noticed his height lost yesterday? And his bones were already 98% consolidated. I don't know. Personally, these are my speculations

1. Inaccurate measurement before (eg. measuring standing on ballerina foot)

2. Spinal compression?

Yup, I have no clue.

I am convinced if you or exercise a lot on the first year after LL you can loose some height.

Why are you convinced of something that doesn't make sense, and for which no evidence exists?

The bone will either stay where it is or break. It doesn't shrink or slide or compress or anything like that.

I'm pretty sure it's the spine compression.

Hey yeah in Swedens case he removes the frames after lengthening cause he inserted nails as well, LON or LATN, not sure. So he cannot have lost height by compression of the gap. so probably spine or inaccurate measurment.

And i know i can make up for lost height during lengthening phase, but as you did, i will probably lay down most of the time to make sure i dont waste time making up for lost height gain.

What i really want to know is if you do externals only like me (which means i need to wear them for like 3 months after lengthening phase is over) then is it possible for the gap to compress while im walking around during consolidation phase? Since i want to fly home to my own country after lengthening is done, i wont be able to make up for any losses that could happen then. But I thought the external fixators would be reliable in holding the bone and the gap in place, so you dont lose any height. Is it really possible for me to lose height during this phase? it doesnt seem reasonable, if its true then i might not dare to go home until the bone is consolidated and i can remove the frames.

Most pin bending happens in the beginning. Once they've bent however much they're going to bend from bearing your weight and resisting lengthening, they're done bending.

Oh i see, i thought for some reason that the doctor would replace pins that began to bend. what you said makes perfect sense though. So when i know the pins cant bend anymore, then it should be safe.

awesome thank you!

On the other hand, i guess that means i need to be really careful in the beginning of consolidation phase, like when im flying home and im carrying my luggage, that would increase the weight load on my fixators, which might cause extra bending? but i guess the pins have a limit to how much they can bend which should already have been reached? unless they break which seems unlikely
