"The height of broken bones" may have serious consequences. Some of them were pulled into crutches with uneven legs, and some were turned into lame people with valgus legs. It's just that walking is too uneven, and what's more serious is osteoporosis. They dare not dismantle the fixed steel frame, and some fall into lifelong illness after dismantling it.

The so-called "broken bone height" is a medical "osteotomy and lengthening" and a surgical method to overcome the imbalance of the length of both limbs (mainly lower limbs). The principle is that human tissues can undergo cell division and proliferation under certain stress stimulation. Human growth needs adequate nutrition and proper exercise. People's height is related to heredity, such as congenital deficiency, lack of nutrition and exercise, and short stature, which can also be achieved through "osteotomy and lengthening of both lower limbs".

According to this principle, combined with modern orthopedic technology, limb osteocytes can be regenerated, thus realizing limb lengthening. This technique was first used in the 1940s and 1950s to treat some patients with congenital limb deformity, trauma and poliomyelitis, and later developed to treat dwarfism. In the 1970s, foreign countries began to try to use this technology to extend the lower limbs of some people with low normal height. In the early 1990s, normal operation began to be applied in medical practice in China.

This operation is a process in which the patient's bilateral tibia (calf bone) is amputated, fixed and pulled by special instruments, so that the broken bone is gradually muscled and ossified, and the surrounding muscles, nerves, blood vessels and other tissues are also prolonged. It is usually advisable to stretch 1mm every day to avoid irreversible damage caused by excessive stretching or excessive traction. The extendable length varies from 5 to 18 cm. It is necessary to closely observe the sensation, skin, color, swelling and surrounding blood circulation of the distal limb during the operation.

This kind of operation may be good news for people who are too short or whose lower limbs are severely asymmetrical to work or live normally, but it is not necessarily desirable to increase their height for the sake of beauty. It should be reminded that this kind of operation has certain risks, and the postoperative recovery time is long, and there may be many complications such as delayed healing of fractures, nonunion, muscle atrophy and joint stiffness.
