Minor fracture 20 days usually can not be fully recovered, the specific situation is that minor fracture generally refers to the fracture is not significantly displaced, or incomplete fracture, so the fracture of the relationship between the fracture is still well maintained, the fracture after rest, braking, can be successfully healed. After 20 days, there is only a small amount of connection of the bone scab, the stability of the fracture end is still poor, and it is not possible to carry out weight-bearing and activities. At this time, the main focus on muscle exercise to promote fracture healing, while improving the edema of the surrounding tissues. Therefore, a minor fracture will not be fully recovered in 20 days, and still need to continue braking and rehabilitation training, and usually the fracture will be fully repaired in 6-8 weeks. In elderly patients, due to osteoporosis, the time for bone healing will be significantly prolonged.
