Open fracture of the calf, how many months can it grow back? For open fracture of the lower leg, generally after the fracture of the lower leg, the surrounding soft tissue damage is more serious, so the fracture healing is relatively slow. According to the normal fracture healing time, generally 72 hours of hematoma mechanization, about 2 weeks of fibrous connection of the fracture end, 4 weeks of the fracture end of the primitive bone scab growth, and then into the mature bone scab period needs about 2 months. So normal fracture healing usually takes about 3 months, there is obvious scab growth and the fracture line blurring. However, for open calf fracture, because the surrounding tissue destruction is more serious, the fracture healing is relatively slower, it usually takes about 5 months to have obvious bone scab growth. If the surrounding tissue destruction is very serious, often accompanied by bone nonunion, that is, the fracture does not heal. Therefore, after the open fracture of the lower leg, it is necessary to minimize the activity within 3 months, and apply the medication of activating blood circulation and removing blood stasis as well as the medication of promoting fracture healing to promote the healing of the fracture. At the same time, hot compresses can be applied to the fracture end to promote local blood circulation, which is also conducive to the recovery of the fracture, and the fracture should be reviewed regularly to see how the fracture is healing.
