As long as the fracture is well aligned and well fixed, adults can heal in about 3 months, and children can heal even faster, in about 1-2 months. A very small number of patients have difficulty growing after a fracture, mainly due to local blood flow, personal constitution, underlying diseases, nutritional status and other factors, which can manifest as delayed healing or non-healing of the fracture. When the symptoms of fracture appear, you must go to the orthopedic department of the hospital in time, so that the doctor can choose the standard treatment plan according to the specific situation, and to carry out standardized rehabilitation training at a later stage to promote the recovery of fracture and prevent the emergence of adverse complications.
