Has anyone had their limbs lengthened by 13 cm?

Edit Post

Hello, forum friends, I am 163cm tall and have a wingspan of 170cm. My body proportions are abnormal and my legs are short. I calculated that if I lengthen my limbs by 13 to 15cm, I can reach the normal level. I would like to ask my friends how long it will take for the tibia and humerus to return to normal after being lengthened by 13cm. I plan to go to Germany for surgery

The most perfect male body proportion is 0.615, and the dividing line is centered on the belly button. My legs need to be lengthened by 14cm to achieve a body proportion of 0.608
