Generally speaking, 4~8 weeks after fracture belongs to the period of bone scab formation, so one month after the left inner ankle fracture surgery, you can review the X-ray film to observe the formation of bone scab at the broken end of the fracture, and judge whether the fracture healing is normal or not. The healing process after fracture surgery is mainly divided into hematoma mechanization phase, bone scab formation phase, bony healing phase, bone shaping phase, in which one month after the fracture healing into the bone scab formation phase, the fracture will appear at the end of the density is lower than the soft tissue, and higher than the normal bone high-density shadow, which is the formation of the primitive bone scabs, indicating that in the fracture after the surgery recovery is normal. After one month, if no obvious bone scab shadow is found through review, it means that the fracture healing is slow or poor, which needs to be examined and judged by the attending physician, and further treatment is needed if necessary.
