It usually takes about 3 months after a sacral fracture to be able to walk on the ground, but at the beginning of walking on the ground, it is best to use crutches or be assisted, and gradually exercise slowly to be able to abandon the crutches and walk independently. Premature walking on the ground will lead to poor healing of the sacral vertebrae, and there will be corresponding sequelae, such as intermittent pain, pain and soreness when encountering seasonal changes, etc. In addition, how long it takes to walk on the ground after a sacral fracture is related to age, physical fitness and the severity of the injury, generally young people can walk on the ground independently within 3 months when the injury is mild, and older people can walk on the ground independently only after about 6 months.
