A 20-day minor fracture usually does not heal well, because a minor fracture usually takes 6-8 weeks to heal completely, but if the patient has a medical condition, is undernourished, or is even an elderly patient, the healing time can be further extended to 8-10 weeks, or more than six weeks in the case of younger patients. Therefore, a minor bone fracture will not heal completely in 20 days, and a significant fracture line and cortical fracture will be found when the X-ray is taken for review. Patients should not bear weight or be overly active, otherwise further aggravation of the fracture will occur, which will affect the smooth healing of the fracture and can lead to delayed healing or non-healing of the fracture, with more serious consequences. Therefore, patients should strengthen nutrition, maintain local fixation, and cooperate with functional exercises to accelerate the smooth healing of the fracture.
