Seventy days after hawksbill fracture surgery, it is in the period of primitive bone scab formation, in which a large number of bone scabs are formed at the fracture site. Fracture healing is theoretically divided into hematoma inflammation mechanization period (about 2 weeks), primitive bone scab formation period (about 2~3 months) and bone scab remodeling and shaping period (about 1~2 years), so the fracture is in the period of primitive bone scab formation at about 70 days, at this time there are a large number of bone scabs formed at the fracture. At 70 days, the fracture is close to the degree of clinical healing, but not completely healed, in this period of time the patient can carry out rehabilitation exercises to prevent adhesion of tendons, but pay attention to the right amount, in order not to cause pain. In addition, it is also necessary to avoid weight bearing on the hand, maintain a healthy mindset, and actively cooperate with the diet in order to promote the early recovery of the fracture site.
