After the fracture, the growth mainly depends on the periosteum, cell proliferation and division of endosteum and epicondyle, gathering to the fracture end, mechanization in the blood of the fracture, and mechanization of fibrous tissue to form a fibrous skeleton, and the fibrous bone scab is usually formed in about 3~4 weeks. The time of formation and performance of bony scabs are different in different parts of the body. Generally, the bony scabs will grow more firmly in about 3 months, and the density and strength are relatively strong, and the scabs will be molded with the activities of the human body, and become more in line with the structure and form of the scabs of the human body.
