A bone fracture is a medical condition where there is a break in the continuity of a bone. This can occur due to various reasons, such as trauma, falls, or conditions that weaken bones, like osteoporosis. Fractures can be classified into different types, including simple fractures, where the bone breaks cleanly, and compound fractures, where the bone pierces the skin. Symptoms of a fracture often include pain, swelling, and difficulty moving the affected area. Diagnosis typically involves imaging tests like X-rays or CT scans. Treatment may vary from immobilization with a cast to surgical intervention, depending on the severity and type of fracture.
