Bone age is short for skeletal age and needs to be determined with the help of a specific image of the bone in an X-ray camera. Changes in human skeletal development are essentially similar, with each bone developing in a continuous and stage-specific process. Bones at different stages have different morphological characteristics, therefore, bone age assessment can more accurately reflect the level of growth and maturity of an individual. Girls stop growing at 17.3 years of age and boys stop growing at 18.4 years of age. After the epiphysis closes, it indicates that the growth is basically over and the possibility of growing taller is not particularly high, but due to the subsequent action of bone cells, it is possible to grow 3 to 5 cm taller. The growth rate of different parts of the human skeleton is not the same, the development of the distal extremities is much earlier than the proximal skeleton development, when the body’s growth rate slows down, the proximal thoracic and cervical vertebrae growth has not completely stopped, there is still a lot of room for growth, so after the closure of the skeleton, through effective methods, can still help grow taller. Specific methods are the following: 1, more calcium: after the closure of the bone age, if more attention to calcium supplementation, to a certain extent can help grow taller. In the daily more active calcium supplements, eat more food containing calcium or can promote the body’s absorption of calcium, such as: milk, beans, animal liver, egg yolk, fish, meat and other foods. 2, reasonable diet: after the closure of the bone age, usually eat more healthy and nutritious food, pay attention to the scientific collocation of diet, to develop healthy eating habits, which can also promote physical development and help grow taller. 3, do muscle stretching training: after the closure of the bone age, by doing some muscle stretching training can also help to increase height. For example: running, jumping, soccer, volleyball, basketball, gravitational upward and other sports, are sports that promote growth and development, through daily practice, even if the bone age has closed, can still grow taller. 4, sufficient sleep: the body after sleep, growth hormone secretion than usual, and last longer, conducive to growth.
