Which signs might indicate an extremity fracture?

Recognizing signs of an extremity fracture is crucial for effective diagnosis and treatment. Swelling and crepitus under the skin are significant indicators of a fracture. Swelling often occurs due to inflammation and bleeding in the area following a fracture, while crepitus refers to a crackling or popping sensation created by the movement of broken bone fragments through soft tissue. The presence of both signs combined strongly suggests that a fracture has occurred, as they are direct physical manifestations resulting from the injury.

Intense pain may accompany a fracture, but it is not exclusive to fractures and can occur in many other types of injuries, thereby making it less definitive on its own. Full range of motion would typically not be observed in the case of a fracture, as the injury usually results in reduced mobility. Skin discoloration can occur due to various injuries and conditions, including bruising or blood pooling from an injury, but it is not specific enough to confidently indicate a fracture. Thus, swelling and crepitus are the most indicative of an extremity fracture.
