hi,
legs height:
https://ibb.co/tZGK2w5
How is the ratio of femur and tibia calculated?
for example:
femur bone : 335mm
tibia bone : 324mm
Thanks.
Quote from: short on August 19, 2019, 11:58:30 AMtibia/femur = 0.8 on average
Thanks.
My ratio result: (335/324)
1,03
if +7cm femur ratio result: (335 + 70)
1,25
if +6cm tibia ratio result: (324 + 60)
0,87
According to these results, is my tibia lengthening better?
Maybe I measured the bone size wrong from the x-ray, but I don't think you're going to notice small mms.
When measuring femur and tibia, the length of the bone is measured?
For example, are my X-ray measurements correct?
Quote from: Polski on August 19, 2019, 02:24:14 PMUr wrong your Ratio is arround 0.96
How do you calculate ?
is 0.96 normal legs ratio? (Non lengthening)
Quote from: Infinity on August 19, 2019, 10:30:39 PMHi James, from where did you got these numbers from? Looking at your x-rays if the numbers are measurements taken from the lines you have drawn than they are wrong. pls look up online to see where the femur and tibia bones start and finish.
I had an X-ray. There are measuring tools from X-ray application.
But I do not know where the lengths of the femur and tibia are measured 
I just measured the size of the main bone. (femur and tibia)
Do you know how to measure? (point to point etc.)

The difference from the other measurement:
I measured the femur from the vertex of the bone.
There is not much information about measurement on the Internet.
I made this measurement by looking at x-ray pictures on the internet.
Size results:
404 / 350 = 1,15
Does my legs have a tibial ratio with the femur?
They say 0.8 in the forum, but the average of femur and tibia in medical research on the Internet is 1.20.
I don't know what the 0.8 value in the forum is.
Quote from: Infinity on August 20, 2019, 09:25:22 AMlooking at x-rays, the new measurements seems more accurate. Tibia line should finish at the end of tibia bone but you are overlapping it to the ankle bone so your tibia measurement might be a little less than you have now.
Your femur to tibia ratio seems standard to me, I am enclosing a link that will show you how to measure tibia and femur length.

Thank you.
What is the 0.8 femur tibia ratio that people say in the forum?
Is that another measure?
Quote from: Infinity on August 20, 2019, 01:04:44 PMIt means that ideally tibia should be about 80% of the length of femur, give or take 2-3 percents. If femur is 40cm than tibia is about 32 cm. Once you will measure correctly you will see that you are with in the acceptable normal range i.e., tibia is between 78%-82% of the femur length is very standard. IMO after lengthening, for the sake of functionality and aesthetics, at most tibia length should be with in 70-90% of the femur length.
Quote from: short on August 20, 2019, 02:25:13 PMexactly!
It's a ratio calculation: tibia / femur = 0.8 means tibia = 0.8 * femur, so tibia = 80% of femur
On the other way: femur / tibia = 1.2 means femur = 1.2 * tibia, so femur = 120% of tibia
It's the same same equation resolved differently.
Thanks. I understand.
0.8 and 1.2 different values but femur and tibia ratio calculation is the same.
I made a simple ratio calculation excel file.
I hope there are no mistakes

Quote from: dunghuynh2227 on October 24, 2019, 10:24:20 AMwhat if i have equal length ? my tibias 39 and femur 39 cm ( I lenghten tibias form 33 to 39cm )
I do not know this
This is only medically to calculate the lower and upper bone proportions.
