100 days after the fracture, that is, about 3 months after the fracture, during this period, the fracture is in the growth of the repair period, has not been completely healed, so this stage should pay attention to a reasonable diet, avoid blind tonic, regular work and rest to avoid smoking and drinking, and actively exercise to avoid the early weight-bearing and so on. 1. Diet: After the fracture because of the reduced activity, should avoid a lot of supplements, eat more rich in protein, multi-vitamin diet, avoid greasy food, eat more crude fiber diet, to prevent constipation, appropriate supplementation of calcium-containing food, to promote healing of the fracture. 2. Work and rest: Avoid irregular work and rest, such as staying up late, avoid smoking and drinking, because nicotine and other substances in cigarettes will hinder fracture healing, and the stimulation of alcohol will make the microcirculation of the fracture tip impaired, causing the contraction or spasm of the microcirculation blood vessels, which will reduce the blood supply to the fracture tip and affect the healing of the fracture. 3. Functional exercise: Functional exercise should be carried out actively after the fracture, but it needs to be carried out under the guidance of the doctor. Early weight bearing will affect the alignment of the fracture line because the fracture scabs have not yet healed firmly, which will easily lead to delayed healing of the fracture or secondary injury. It takes 100 days for a fracture to heal, and fracture patients should be treated actively under the guidance of a doctor, as long as they keep their mood happy and standardize their treatment and rehabilitation, they should be able to regain their health soon.
