Which of the following is a common place for pressure ulcers?

• A. Greater Trochanter
• B. Elbow
• C. Shoulder Blade
• D. Face

Answer: (A)

Pressure ulcers form when sustained pressure over a bone compresses blood vessels and reduces blood flow to the overlying skin and soft tissue, leading to ischemia and tissue damage. Areas with prominent bones and little surrounding padding are most vulnerable, especially in people who are immobile or unable to shift position.

The greater trochanter—the prominent bone on the outer hip—is a common site because it has thin soft tissue coverage and bears substantial pressure when someone lies on their side or sits with weight on the hip. While the elbow, shoulder blade, and face can develop ulcers under certain circumstances, they are less typical in the usual bedridden elderly patient compared with pressure over the hip region. Preventing ulcers involves regular repositioning, offloading pressure with pads or cushions, and maintaining skin care and good nutrition.
