The impact of prominent bony features on pressure sore development is significant, as these features can increase the risk of compression. When bony prominences are exposed or come into contact with hard surfaces, they create pressure points. This pressure can restrict blood flow to the skin and underlying tissues, leading to tissue ischemia and, ultimately, pressure sores or ulcers.

In settings where individuals may be immobile for extended periods, such as in medical facilities or for individuals with certain disabilities, the presence of prominent bony areas means that these locations are more likely to endure prolonged pressure. The combination of this compression, alongside other factors such as moisture and friction, can greatly contribute to the formation of pressure sores.

While weight distribution, reduction of shear and friction, and enhanced mobility are relevant factors in the discussion for overall skin health and pressure sore prevention, they do not directly address the specific challenge posed by bony prominences. In contrast, the increased risk of compression at these sites is a clear and direct correlate to the development of pressure injuries.
