A closed fracture is a type of bone break where the skin remains intact, meaning there is no open wound at the fracture site. This type of fracture can occur due to various causes, such as falls, sports injuries, or accidents. Closed fractures can vary in severity, from hairline cracks to complete breaks. Diagnosis typically involves imaging techniques like X-rays to assess the extent of the injury. Treatment often includes immobilization with a cast or splint, and in some cases, surgery may be necessary to realign the bone. Proper healing is essential to restore function and prevent complications.
