To prevent external rotation of the legs when applying a Pelvic Compression Device (PCD), what should be done?

When applying a Pelvic Compression Device (PCD), securing the knees and/or feet together is essential to prevent external rotation of the legs. This is important because external rotation can compromise the effectiveness of the PCD in stabilizing the pelvic area and controlling hemorrhage. By keeping the legs aligned and together, the device can apply appropriate pressure to the pelvis, reducing the risk of further injury or instability.

Other options, such as elevating the legs, wrapping the thorax, or maintaining hip extension, do not specifically address the concern of external rotation. Elevating the legs may actually increase the risk of external rotation rather than mitigate it. Wrapping the thorax does not influence the position of the legs directly, and maintaining hip extension does not provide the necessary stabilization to prevent rotation at the hip joint. Hence, securing the knees and/or feet together is the most effective intervention for this particular situation.
