What should you do if you identify an open fracture?

In the case of a long bone fracture, as illustrated in the attached graphic, the basic principle of first aid is to immobilise the two adjacent joints (above and below the fracture site). This action, consistent with the so-called Pott's rule, prevents the displacement of bone fragments, which protects the victim from pain and additional damage to soft tissues, nerves, or blood vessels. In the case of open fractures, do not stretch the limb or use fibrous materials (such as cotton wool) directly on the wound.
