Yesterday, I saw a 30-year-old woman who had a fracture of the fifth metatarsal of her left foot, which was not greatly displaced. Although the doctor repeatedly ordered it, the patient either kicked the object with her foot or stepped on the ground with weight on her left foot during the period of cast immobilization, and as a result, there was no obvious bone scab growth in the 8-week film. Here we emphasize that fracture braking is the first priority, only when the fracture end is stable, the fracture can heal; improper activities, the fracture will naturally grow slowly if the fracture end is displaced beyond its own repair ability. In addition, the fracture is displaced and painful, some patients rely on pain medication without other treatment, which is not very useful and may damage the stomach, affect the absorption of nutrients and affect the health. Therefore, it is important to reset and then keep the fracture stable.
