Linear fractures are breaks in a bone that occur in a straight line. These fractures can happen due to various reasons, such as trauma, stress, or overuse. They are often seen in long bones, like the femur or humerus, and can vary in severity. Diagnosis of linear fractures typically involves imaging techniques like X-rays or CT scans. Treatment may include rest, immobilization with a cast, or in some cases, surgery. Proper healing is essential to restore the bone's strength and function, allowing individuals to return to their normal activities.
