What are common signs of a fractured bone?

A fractured bone typically presents with a distinct set of symptoms, which include pain, swelling, deformity, and an inability to use the affected limb. Pain is often immediate and severe, as the fracture can cause damage to surrounding tissues, nerves, and blood vessels. Swelling tends to occur rapidly due to inflammation and fluid accumulation in the area. Deformity can manifest as an abnormal angle or position of the bone, indicating a break. Finally, the inability to use the affected limb, either due to pain or mechanical instability, is a key indicator that a fracture may have occurred.

The other choices do not encompass the full range of indicators that would conclusively point to a fracture. Light bruising and redness may suggest a soft tissue injury rather than a fracture. Pain only during movement does not reflect the potential for severe pain that exists at rest in many fractures. Swelling with increased temperature may not specifically relate to bone fractures and could indicate other conditions, such as an infection or sprain. Thus, recognizing the comprehensive signs highlighted in the correct choice is crucial for identifying a fracture.
