Pressure ulcers are usually found on bony parts of the body, but can occur almost anywhere that pressure has been applied for a period of time. Ulcers generally appear where bones are close to the skin and where the skin presses against a firm surface, such as a chair or mattress.
The areas prone to pressure ulcers for various different positions or postures are as follows:
- When sitting: tail bone (coccyx), buttocks (ishium), backs of heels, elbows, shoulder blades
- When lying on your side: ear, side of your shoulder, pelvis, hip, knee, ankle bones (malleolus)
- When lying on your back: back of your head, shoulder blades, elbows, tail bone (coccyx), heels, toes
