Bone fractures, as the name suggests, refers to a crack-like fracture in a bone. Although it is a simple fracture and the bones are not obviously displaced, maintaining proper alignment is still important. However, a fracture does represent a change in the continuity of the bone. If effective repositioning and fixation are not carried out, displacement of the fracture can occur. Therefore, it is generally advised for patients to use a cast or a brace for external fixation. If the patient moves frequently without effective fixation, the crack fracture may develop into a displaced fracture. Once a displacement occurs, it can become complicated, potentially requiring surgical treatment. Therefore, patients with bone fractures are advised to rest and avoid vigorous activities, and to ensure effective repositioning and fixation.
