I think you lose 0.3-0.4mm due to compression if I'm correct?

It's a tough choice for me cause I'd want 6cm and not lower, however I know there are more risks once crossing 6cm so I'm not sure cause 6.4cm all of a sudden seems much bigger risk

I'm curious to know more about this as well, did you ever find anything out that was concrete @GeTs?

Depends on the device, with monorials at most you Will get .3 mm less, with Ilizarov there is generally a larger lose. Some Catagni patients lose something near to 1.5 cm.

I have read there are higher infections rates with LON. Not sure about LATN

I personally wouldn't really care about how much further to lengthen to reach a specific height because there are safe limits that you should never exceed (~20% of original bone length). So I would just try to lengthen as much as possible within the safe limits regardless of the amount of lengthening because even if you didn't reach your lengthening goal, you shouldn't be lengthening beyond the safe limits anyway!

That's crazy, someone not knowing going for and expecting to be 5'9 would end up barely 5'8 in this case. Imagine all that time, effort and money to be a whole cm and half shorter than planned.

Yes, that is the disadvantage of external fixation

I don't think it happens to all external fixation cases, at least at that degree.
In my case I haven't lost anything (or at least not more than 2mm which is almost non countable).

Bodybuilder, you remember the idiot that said he got his frames removed in 4 months without a nail. He said he had lost half a cm. Maybe it is that those who aren't ready to have their frames removed without support or being ready risk losing some height.

Thats my point. If callus formation is 100% then with internals or externals I can't understand how you could lose height, especially that much.
If someone waits about 45-50 days for every cm he lengthens then I doubt if they lose more than 1-2mm after frame removal.

Yes, do you know if subsidence exist when you only use Internal Nails? That thing according to some docs, like Dr.B, is not fully understood yet.

I don't think that subsidence can happen with internals as when you take them out the bone is fully consolidated.

I don't really know when it happens as I didn't have it in my case but as I said I believe that if your bones are completely consolidated it won't happen.
So the only thing an LLer can do is to be patient and take fixators out only when the callus is very strong.

Maybe walking while in fixators can compress the callus a little bit, but you dont cant fight with eqiinus if you dont do It.
