Fractured bone is a verbal term used by the common people, which literally means that there is a crack in the bone, but it is not completely broken. There is no clinical diagnosis of “bone fracture”. So what does “fractured bone” belong to? By definition, a “bone fracture” is actually a cracked fracture, which is subordinate to a fracture and is a type of bone fracture. Since this type of fracture does not displace significantly after it occurs, and most of them do not show up clearly on X-rays, the probability of missing the diagnosis is very high. Usually, the pain in the affected area is not relieved after 2-3 weeks, and after reviewing the X-rays and comparing them with those taken at the time of the injury, signs of fracture healing and bone scab formation can be seen. Most avulsion fractures are treated conservatively and have a very good prognosis, but in cases where articular surfaces are involved, the impact on joint function needs to be weighed to determine the treatment plan. What about avulsion fractures? Avulsion fracture, in fact, is under the action of external force, as well as muscle contraction, the attachment point of tendons and ligaments on the bone was torn out of the small bone, clinically speaking, also belongs to a kind of bone fracture, just because the fracture block is relatively small, ankle sprain of the inner ankle or the outer ankle of the avulsion fracture is more common. Due to the very small fracture fragments, avulsion fractures are usually treated conservatively, and in the long term may lead to pain in the affected area with activities, while the exact degree of pain varies from person to person.
