For patients with cracked pelvic fractures, it is generally necessary to rest for about four weeks before they can gradually get down on crutches and engage in light weight-bearing activities. Although the pelvic area cracked fracture, the fracture end of the alignment of the line is relatively good and the pelvic area of the bone is cancellous bone, blood good, this fracture recovery is relatively fast, but the fracture recovery, stabilization is also need time, general fracture end of the four weeks before the growth of primitive bone scabs, will be relatively stable. Therefore, even if the patient’s fracture is a cleavage fracture, it is necessary to rest for four weeks, after the fracture is stabilized and the primitive bone scab grows, then the patient can go down to the ground, in order to avoid going down to the ground too early, which will affect the recovery of the fracture, and it is easy to lead to the displacement of the fracture after the excessive force is put on the fracture.
