Title: how much should I lengthen?
Post by: Jokerhastowait2022 on September 10, 2020, 02:59:43 PM
Hey there LL community!

I'm a 19 years old male, and I am thinking about doing LL for both tibia and femur. I've already made my mind on how much I want to increase in tibia which is 5cms, but not sure how much I should lengthen in femur in order to maintain the healthy proportions. Hope you can help me decide.

current night height/ morning height:173 cm /175 cm
wingspan: 174cm
tibia length: 37.5 cm
femur length:45 cm
torso - head: 56.5 cm/25.5 cm
body type: Endomorph

Thank you for your replies in advacne.

If u want .8 tib/femur ratio for ideal arthritis reduction then you need to do 8cm Femurs, at least 7cm. For arthritis reasons. But unless u x-ray legs then u probably are measuring them wrong anyways so ignore everything until u get an x-ray if u really care about the numbers

dear ghkid2019, thanks for your reply, but I don't understand the relationship between tibia/femur ratio and possible arthritis complications, can you clarify this for me? Moreover, I don't get why an x-ray is necessary for measurements. can you also elaborate on that?
Don't you think 7-8 cm increase in femur is a bit excessive for a 174 wingspan?

Scientific studies show the optimal ratio for Tibias to Femurs is 0.8. any deviation will more likely result in arthritic issues versus a simple 0.8 ratio.

And x-rays are needed because what you're feeling may not be really what you feel. You might be adding 2 cm cuz thicc skin or whatnot and minding 3cm because u measuring the wrong part of bone. Blah blah

Wingspan is an opinionated question, so I don't answer
