The presence of scab growth indicates that the entire fracture site is in the process of healing, but not complete healing. After the fracture, there is a period of hematoma as well as a period of scab formation and shaping of the fracture site. The fracture site is not very solid during the whole process of scab growth, and no part of the fracture can be fully weight-bearing at this time, only non-weight-bearing functional rehabilitation exercises of the adjacent joints can be performed to promote the recovery of muscle atrophy, promote blood circulation to the fracture site, which is conducive to accelerating the growth of scab and promoting the healing of the fracture. After that, it is still necessary to review the fracture after a period of time to observe the maintenance of the fracture position and the healing of the fracture, and then decide whether the next step can be weight-bearing functional rehabilitation exercises, or to determine whether the fracture can be 100% healed to carry out normal daily life.
