What are the most common sites of junctional hemorrhage?

The most common sites of junctional hemorrhage are indeed the proximal thigh and groin. Junctional hemorrhage refers to bleeding that occurs at anatomical junctions of the body where major blood vessels are located and are particularly challenging to control in tactical or combat situations. The proximal thigh and groin area are critical regions due to the presence of the femoral artery and vein. In cases of trauma, injuries to these vessels can result in significant blood loss, making it a high-risk area for junctional hemorrhage.

In tactical combat casualty care, recognizing and effectively managing hemorrhage at these sites is crucial, as it can significantly impact the casualty's chances of survival. Techniques such as applying a tourniquet or direct pressure may be necessary to control bleeding in these locations.
