I am 15yo and currently 5'5, however I am coming towards the end of my growth. I am planning to lengthen 5cm Tibia, 5cm Femur, 3cm Radius and 3cm Humerus since I have very short limbs. How can I achieve this lengthening in the shortest time frame and which doctor will do this? (I am going to wait till I am 21/finished university to get surgery)
