After fracture surgery, the bone scab can be attached in about two weeks, but in small amounts, as primary scab formation. On radiographs, the fracture site is surrounded by a pike shaped scab shadow, but the fracture line is still faintly visible. This is followed by a period of scab remodeling and shaping, in which new trabeculae are gradually added to the primary scab and the arrangement becomes more regular and dense. Necrotic bone at the fracture end is revived by removal of dead bone and crawling replacement of new bone formation, and a complete bone scab connection is formed at the fracture site, a process that usually takes 8-12 weeks. After the above process, the fractured end will be completely repaired to achieve clinical bony healing, and the patient can resume normal activities, normal life, and can gradually resume sports.
