Quote from: azr on January 12, 2021, 06:56:03 PMWhat if you split it tho ? 4cm first year then 4 cm next year ?
One year Gap let's you stretch out everything with time and it'll be very doable so the concern at that point if you space two surgeries apart will shift to whether you are fine with the proportions provided by 8cm Tibias
I am 160 cm so to only gain 8cm and be 168cm will NOT (In my opinion) be that much life changing. Thats why i m considering +16cm.. And the safest way will be to split it. 176cm seems reasonable Plus i ll be like the world approximate average.. I m really thinking this is the ONLY option for me

The whole 8cm tibias in two 4cm lengthenings needs to be explained way more. So over 5cm and it's a hard stop according to Paley yet 8cm split is ok. The soft tissues and tendons don't get naturally longer they are still stretched out just the same. What mechanism makes 8cm ok if split?

You can also generally get more growth if you do femurs and tibias separately as opposed to together. The reason is because often times the muscles struggle to grow enough and the break gives your muscles a chance to catch up.

None that I'm aware of. Just do your 8 cm if you want 8 cm.

Formerkidds point makes sense that doing 8cm split into 4cm each gives muscles a chance to recover but ultimately your ligaments and tendons don't get any longer they just stretch so your going to have the same issues on tibias anyway.
Does anyone know any diaries where anyone has done 8cm tibias with Paley split into 4cm lengthenings?

Paley (and I think most reputable doctors) will make you slow down or stop if the muscles get too tight. I was told there are some risks of damage if things get too far out of wack, although I don't know the specifics.

This is wrong! Look up distraction osteogenesis in limb lengthening. Yes your soft tissues do stretch, however they also grow due to the mechanical stretching force, similar to how your soft tissues get longer during your growth spurt in puberty.
The reason why its better to split 4 cm and 4 cm a year apart is so that the soft tissues have time to actually grow. Remember soft tissues don't grow as fast as bone, and a distraction rate of 0.5mm/day to 1mm/day is way too fast for your soft tissues to keep up. This can cause nerve damage or scarring/fibrosis.
Do your research before spreading misinformation please!

In all of cyborg4lifes interviews with Doctors from Paley to Lee they all said the bone can be lengthened much further than soft tissue due to limits with the tendons and ligaments having fixed amount of stretch in them. I can't find any information which shows that ligaments and tendons will grow and not stretch. Can you link any sources.

The soft tissues are the limiting factor because like I said they don't grow fast enough to keep up with the lengthening of .5 to 1mm/day. Paley himself has said the soft tissues grow as well.
" Ilizarov in 1951 began developing his methods of “distraction osteogenesis”. He developed the process of new bone (termed regenerate) and soft tissue regeneration under the effect of slow and gradual distraction. Gradual traction on living tissue creates stresses that can stimulate and maintain the regeneration and active growth of certain tissue structures, termed the “law of tension stress” (Ilizarov, 1989; Paterson, 1990). "
Seriously look up distraction osteogenesis. It is the process being used in limb lengthening. Study up on it, and rewatch the Rozbruch and Paley interviews they mention it briefly too.
