What symptom does fracture heal period have?
summary
The process of fracture healing can be divided into three stages: 1. Hematoma organization stage, in which the growth of fiber connection takes about 2 weeks. The callus formation stage, that is, the fracture has reached the clinical healing stage, which takes about 2 months. In the callus shaping stage, the bone marrow cavity is recanalized, and it takes about 2 years to recover. One hundred days of injury. Listen to the doctor and take care of yourself. What symptom does fracture heal period have? Let's talk about it
What symptom does fracture heal period have?
Hematoma was formed in the fracture, and the fracture end was necrotic due to the interruption of circulation. Hematoma clots, necrosis caused aseptic reaction. With fibrin exudation, capillary proliferation, fibroblasts and phagocytes invasion, the organized hematoma was gradually removed, granulation tissue was formed, and then evolved into fibrous connective tissue, making the fracture end become fibrous connection. This process was completed 2 weeks after fracture.
The proliferation of osteoblasts in the periosteum and periosteum leads to the formation of new bone inside and outside the fracture end (endochondral bone). The new bone increases continuously and makes both ends heal to form fusiform, which is called internal callus and external callus. The fibrous connection between fractures and medullary cavity transforms into cartilage tissue, which is called endochondral bone, and forms annular callus and intramedullary callus at the fracture site. The original callus was formed after the two kinds of callus healed. It usually takes 4-8 weeks.
The new bone trabeculae in the original callus increased gradually, arranged regularly and compactly, the necrotic bone at the fracture end was removed continuously, and the new bone was replaced by crawling resurrection, then the fracture site formed a bony connection, which generally took 8-12 weeks. With the limb movement and weight-bearing, the callus on the stress axis was strengthened, the callus outside the stress axis was removed, the medullary cavity communicated again, and the normal structure was restored. The fracture marks were completely removed.
matters needing attention
Fracture patients, often accompanied by local edema, congestion, bleeding, muscle tissue damage and other conditions, the body itself has the ability to resist these repair, and the body repair tissue, long bone muscle, callus formation, blood stasis and detumescence of raw materials is to rely on a variety of nutrients, it can be seen that the key to ensure the smooth healing of bone fracture is nutrition.
