What factor enhances the effectiveness of a sling and swathe for mid-humerus fractures?

The effectiveness of a sling and swathe for mid-humerus fractures is significantly enhanced by the stabilization of both the shoulder and elbow. When both joints are stabilized, the movement of the fractured mid-humerus is minimized, which helps to reduce pain and prevent further injury. This stabilization supports the limb in a position that maintains alignment and can facilitate healing by confining the fracture to a stable environment.

While additional padding, the application of ice, and elevation of the limb can offer benefits in terms of comfort and swelling control, they do not directly contribute to the immobilization and stabilization critical for managing a mid-humerus fracture. Proper positioning and stabilization of the adjacent joints are paramount to ensuring that the broken area is kept still and secure, which is the primary goal in fracture management.
