A linear fracture is a fracture in which the fracture line is clear and the fracture end is normal. It is called linear because it looks like a line segment on the x-ray and there is no change in the shape of the fracture; this type of fracture is a relatively minor fracture. This type of fracture is also called a crack fracture, which can also be imagined as a piece of glass that has been dropped and cracked, but not broken. It is usually a linear fracture caused by external forces and violence, and the basic symptoms are painful movement and redness and hematoma in the injured area. Patients with linear fractures should seek timely medical attention from orthopedics, thoracic surgery, and neurosurgery according to their condition, as timely treatment can heal and will not leave sequelae. In addition to medical treatment, patients should also take care of their daily life and diet, such as preventing secondary injuries caused by falls and excessive exercise at home, and eating a diet high in protein, vitamins and calcium.
