It takes about 8 weeks to walk on the ground after a foot fracture. 2-4 weeks after the fracture is the period of local hemorrhage and hematoma mechanization, in which the local hemorrhage and hematoma undergoes fibrosis and thus the local hemorrhage and hematoma is gradually absorbed. The primary bone scab formation period is 4-8 weeks after the injury, which allows the formation of the primary bone scab through intra-membrane osteogenesis and endochondral osteogenesis, thus completing the initial connection of the fracture ends. The period of 8 to 12 weeks after the fracture is the bone shaping period, through the shaping of the primary bone scab, the shape of the fracture area is restored to the state before the fracture, and the strength of the bone is obviously enhanced. At about 8 weeks, the fracture should be reviewed and X-rayed to see if the fracture is initially healed and stabilized, and then the fracture can be put on the ground with the help of crutches for weight bearing.
