As for the question of how long the process of bone scab growth, usually, it takes about 4-6 weeks for the growth of bone scab to be in the period of primitive bone scab formation, and 6-8 weeks later, it is in the period of mature bone scab formation, which is the time needed for the process of bone scab growth. However, there are many factors affecting the growth of the fracture scab in clinic, such as the age, physical quality, the severity of the injury at that time, and the degree of active treatment and protection at a later stage, which will affect the process of the patient’s localized growth of the bone scab. If the patient has diabetes mellitus, it will affect the patient’s local bone scab growth, for such patients must actively control blood sugar, control blood sugar within the normal range, more conducive to promote the growth of bone scab. At that time, the injury is very serious or localized comminuted fracture patients, will also affect the later growth of bone scab.
