A fracture can cause swelling in the leg due to the body's inflammatory response to injury. When a bone breaks, blood vessels around the fracture may be damaged, leading to bleeding and fluid accumulation in the surrounding tissues. This influx of fluid, along with the release of inflammatory substances, results in swelling as the body attempts to protect and heal the injured area. Additionally, swelling can also occur from muscle spasms and the immobilization of the leg.
