A fracture is a medical term that refers to a break in a bone. This can happen due to various reasons, such as accidents, falls, or conditions that weaken bones, like osteoporosis. When a fracture occurs, it can cause pain, swelling, and difficulty moving the affected area. There are different types of fractures, including simple fractures, where the bone breaks cleanly, and compound fractures, where the bone pierces the skin. Treatment often involves immobilizing the bone with a cast or, in some cases, surgery to realign the broken pieces. Proper healing is essential for restoring strength and function to the bone.
