What is the most effective method for reducing swelling in a fracture?

The most effective method for reducing swelling in a fracture is the elevation of the fractured limb. Elevation helps minimize swelling by promoting venous return, which decreases the hydrostatic pressure in the dependent limb. When a limb is elevated above the level of the heart, gravity assists in reducing the accumulation of fluid in the tissues, which is a common response to injury.

In contrast, applying heat can exacerbate swelling because it increases blood flow to the area, potentially worsening inflammation. Increased physical activity is typically not advisable immediately after a fracture, as movement can lead to further injury and increase swelling. Immobilization with a brace is beneficial for stability and pain management, but alone it does not effectively address edema since it does not aid in fluid return as elevation does. Thus, elevation stands out as the most direct and effective strategy for managing swelling following a fracture.
