Fracture healing takes about 8 to 12 weeks; during this time, it passes through the hematoma mechanization phase, the scab formation phase, and the scab remodeling or remodeling phase. 1. Hematoma mechanization phase: This phase takes about two weeks. Two to three days after the fracture, the hematoma around the fracture begins to be replaced by granulation and is gradually mechanized, followed by fibrosis to form a fibrous bone scab; about one week later, the proliferating granulation tissue can be differentiated to form hyaline cartilage. 2. Scab formation period: this period takes about 4~8 weeks, firstly the fibrous bone scab is formed. Afterwards, the fibrous bone scab gradually differentiates into osteoblasts, which form bone-like tissue, and then transforms into woven bone. Finally, a bony scab is formed, which is visible on X-ray as a shadow of the scab, and the fracture line is faintly visible. 3. Scab remodeling or remodeling phase: This phase takes about 8 to 12 weeks. In order to withstand the stresses of bone movement, the woven bone is further modified to become laminated bone. This process takes place in concert with osteoblasts and osteoclasts. For patients with bone fracture, they should immediately go to the relevant departments of regular hospitals for treatment under the guidance of professional physicians to avoid delaying the condition; after treatment, they should also follow the doctor’s instructions and do a good job of recovery.
