A bone scab is not the only indicator of walking, so there is no such thing as a bone scab that has to grow to a level where you can walk. Bone scab mainly refers to a cartilaginous, fibrous, bony structure formed during the repair process after the fracture. Generally speaking, bone scabs are divided into internal and external bone scabs, internal bone scabs, which grow in the cancellous bone, and external bone scabs, which grow outside the bone cortex. The end of the fracture, as well as the surrounding bone crust, is differentiated from intramembranous osteoblasts as well as from osteocytes within the cartilage. Generally speaking, when the patient takes the radiographs, if there is already found to be obvious growth of the bone scab, the fracture site healing is relatively good, and there is no localized pain, you can generally walk on the ground. But patients must pay attention to when walking, not fully weight-bearing, need to walk on crutches, and walking time should not be too long, so as not to affect the patient’s recovery. Because each person’s fracture site is different, the degree of injury is also different, so we recommend that patients must pay attention to good care after the fracture.
