Which is the most common site for a pressure injury?

The sacrum is the most common site for pressure injuries due to its anatomical location and the significant contact it has with surfaces during prolonged immobility. The sacral area experiences pressure from the weight of the body, especially when an individual is lying in a supine position. This region has a high-risk profile because it is located over a bony prominence, which makes it more susceptible to pressure-related damage when circulation is compromised.

In circumstances where patients have limited mobility, such as those who are bedridden or have diminished sensation, there is an increased likelihood of sustained pressure on the sacrum. This can lead to tissue ischemia and subsequent breakdown, forming ulcers if not properly managed with repositioning and pressure relief interventions.

While other areas like the back of the head, hips, and heels can indeed develop pressure injuries, they are less common than the sacral region. The heels and hips may be affected, especially in specific patient populations or positions, but the sacrum remains at the forefront as the primary site for these injuries due to its vulnerability in general healthcare settings.
