After the systemic treatment of fracture repositioning and fixation, patients can take some oral bone grafting medication to promote fracture healing, and the duration of oral bone grafting medication can be decided according to the degree of fracture comminution and their own conditions. Generally, oral bone grafting medication can be taken for 6-12 weeks, because the healing after fracture is divided into 3 stages, including the hematoma mechanization period, which is about 2-4 weeks, and the bone scab formation period, which is about 6-8 weeks, and the bone scab shaping period. Oral bone-setting medications have a role in the process of scab formation and can promote fracture healing. As the scab gradually hardens and bone strength increases, there is no need for oral bone-setting medications. However, the type of fracture is different for each person, the healing time of simple fracture and comminuted fracture is different, and the healing time of fracture is different for osteoporotic patients and young adult patients, so there is a difference in the time of taking oral bone-setting drugs.
