Bro I HIGHLY disagree with your last comment. If you go in with an “anything less” is dissatisfaction. You’re looking at it wrong. It should be looked at - basically what cyborg stated.
What’s the most gain with MINIMAL complications. And it seems the majority TOP doctors who are well respected and in ANY country , state 7cm femurs and 6 tibia as MAX. Which means it’s pushing it. Regardless of how far the nail can go.
So if you want that 3 in height. An internal rod on femurs technically goes to 8. You do the 7.5cm there and you’d be okay BUT the safest distance area apparently based on studies was 6.5cm on femurs and 5cm on tibia. It doesn’t make sense to get a height just to be crippled and disabled.
Pay attn to a lot of REAL diaries on here. Everyone past 7cm has BIG issues. Under 6cm had issues but was EASILY rectified/restore to within 90% or more of pre -ll.
I think you need to focus on how to get to 5’10.5 SAFELY. And not let these forums hype you up. B/c a lot of ppl hyping you ain’t even done a consult yet lol.
Be easy. And hope you safely get what you want
Can you share the data around femur > 7 cm is high risk of big issues? I recently did 8 cm on femurs at Paley, and met several other patients who did the same, and I think 8 cm on femur with a healthy recovery (at or near pre LL athletic ability) is very much possible. This is in the context of the average adult, not individuals who are world class athletes who make a living off of competitive sports......the average guy or gal who walks daily, may go for a casual jog or run, may play a light pickup game of b ball every so often, etc.......
There are a lot of other factors at play, for example, the patients starting height. I would argue that a taller guy like myself (starting height 5'9) doing 8 cm, has the same, or even less risk, than a shorter guy (e.g. starting height 5'4) who is doing 7 cm femurs simply based on relative length %.
Overall, I agree with your message that LLers should balance and optimize height gains and functionality, but I don't think its as simple as saying > 7 cm = big issues, there are many variables at play (e.g. starting height, age, muscle mass, natural flexibility, lifestyle, etc.)
