Whether or not a fracture can be weight bearing or walking on the ground and functional exercise at 2 months must be decided according to the specific fracture site and the growth of the bone. If the fracture is an ordinary femur shaft fracture, knee fracture or upper middle tibia fibula fracture, or foot fracture, there is obvious growth of the bone scab in 2 months, and you can start to bear weight or walk on the ground, functional exercise. However, in the case of femoral neck fracture, intertrochanteric fracture, lower tibial fracture, and fractures of the navicular and talus of the foot, the blood circulation in these areas is not as good, and the growth of the fracture is relatively slow, so it is not yet possible to start weight-bearing or walking.
