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 reasons, such as falls, sports injuries, or accidents. The bone may be partially or completely broken, but the surrounding tissues are generally not exposed to the outside environment. Diagnosis of a closed fracture typically involves imaging techniques like X-rays, which help visualize 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 strength to the affected area.
