Actually, there is humerus lengthening (arm lengthening). I knew some LL'ers that also took humerus lengthening post LL surgery. I think I know a user named Polycrates that did HL after he changed his height to 6'3. So there's still hope for you. But it will cost you more time and money to finish it. I think you can pull it off and live your life at the height you wanted and deserve. A lot of people have height dreams, not only you and me, but the majority of the people out there. And height dreams vary from someone suffering from extreme dwarfism that wanted to be 5'5 instead of 4'9. Or even that infamous Apotheosis dude that went from 5'6 to 6'2 and idk how the heck he looks accurate to a natural 6'2 guy. And even 7footers dislike being 7ft tall and they can change that through Limb Shortening surgery. Everyone has dreams and goals they wanted to reach and no one should be discriminated about it either because this is your choice, not theirs. Absolutely NO ONE can stop you because this is your dream and you can make it happen. Just put your mind to it, take some time and hard work and your wishes will come true. This doesn't count for you or me, but everyone. You only live once you know?
