What do I do?

Edit Post

My English is not good, please forgive me.Asian people have a lot of short arm,I am one of them.

My wingspan is about 157cm  and my body height is about 160(night)-162cm(morning).I aims to lengthen by 7cm femur to reach about 167cm.Maybe I'll become a monster?
Arm surgery seems to be very dangerous? Please give me any suggestion.

thanks
