Fracture surgery after 40 can recover well, need to combine the fracture site, the patient’s age, there is no serious underlying disease, at the same time need to combine the severity of the patient’s fracture judgment, for most of the fracture 40 days can not be fully recovered. 1. Fracture site: generally the recovery cycle of upper limb fracture is shorter than that of lower limb fracture, but generally at least 6~8 weeks. 2. Patient’s age: generally the younger the age, the faster the recovery cycle. Especially for children’s fractures, many of them can see the growth of bone scab in about 40 days, but for the fracture of lower limb weight-bearing position, even if there is growth of bone scab, it can’t reach the standard of full recovery. 3. Whether there is underlying disease: If the patient has serious underlying disease, such as low albumin, diabetes, the recovery cycle will be longer than normal, delayed healing or non-healing of the fracture. 4. Fracture severity: for serious comminuted fractures, the recovery time is relatively long, even longer than the normal recovery cycle. There are many factors that affect the recovery of fracture and they vary from person to person. It is important to follow up on time to determine the growth of the fracture and evaluate it with plain radiographs before proceeding to the next step in the treatment program.
