A break in the integrity or continuity of the bone is called a fracture. Based on the degree and morphology of the fracture, it can be classified as an incomplete fracture or a complete fracture. Incomplete fractures include: (1) cracked fractures: also known as bone fractures, fractures resemble cracks in porcelain, without displacement, and are mostly seen in fractures of the skull, iliac bone, etc.; (2) green branch fractures: fractures are similar to the situation when a young branch is broken, and are mostly seen in children, as children’s bones are softer and therefore less likely to break. Complete fractures include: transverse fracture, oblique fracture, spiral fracture, comminuted fracture, insertion fracture, compression fracture, depression fracture, scale separation, etc. As can be seen, bone fracture is a kind of fracture, which does not lead to the displacement of the fracture end, but only the disruption of the continuity of the bone, but the integrity of the bone still exists, the pain of patients with this kind of fracture is relatively small, and the clinical manifestations are less obvious. Treatment of fractures is mainly conservative, with external fixation in a plaster brace or brace. The fracture heals quickly and usually leaves no sequelae due to the fracture, so treatment is relatively simple and easy. However, it is easy to miss the diagnosis.
