How long to take bone grafting medication after a radius fracture must be determined by the age of the patient and the specific growth of the fracture. In the case of a normal adult with adequate nutrition, the bone-setting medication can usually be discontinued after about 4 weeks of taking bone-setting medication. After 4 weeks, you can review the photos and if you see a blurred fracture line, which proves that there is primary bone scab growth, you can stop taking bone-setting medication at that time. In the case of middle-aged and elderly patients, osteoporotic patients or patients with poor nutrition, taking bone-setting medication can be extended for 2-4 weeks as their fracture growth is relatively slow, and the medication can also be discontinued if the fracture line is blurred in the review photos around 6 weeks. However, in the case of children or infants, as their fracture growth ability is relatively good, they usually do not need to take bone-setting drugs, and the fracture can heal normally.
