The absence of swelling does not necessarily mean that there is no fracture. There are some fractures that can indeed have no swelling in the soft tissues surrounding the fracture, due to the relatively small amount of violence and less invasion of the soft tissues adjacent to the fracture site, and therefore, do not result in significant swelling of the limb as well as the fracture site. The proprietary signs of a fracture do not include the presence or absence of swelling as such, but mainly the presence or absence of significant deformity, bone rubbing sounds, bone rubbing sensation, and paradoxical activity. For relatively specific fractures, such as bruxism and cleft fractures, the absence of significant fracture displacement can result in no swelling of the limb and the fracture site as usual, or even only mild pain.
