Why are bony prominences susceptible to skin damage?Asked by: Danial Lang

Bony prominences are the areas of bone that are close to the skin's surface. These areas are most susceptible to pressure injuries because they have the least amount of cushioning. Which pressure points are vulnerable for a particular patient depend on the position in which most of that patient's time is spent.View full answer
Accordingly, Why do pressure ulcers usually occur over bony areas?
For people with limited mobility, this kind of pressure tends to happen in areas that aren't well padded with muscle or fat and that lie over a bone, such as the spine, tailbone, shoulder blades, hips, heels and elbows. Friction. Friction occurs when the skin rubs against clothing or bedding.
Beside the above, Which areas of the body are most susceptible to pressure injuries?. The most common sites are the back of the head and ears, the shoulders, the elbows, the lower back and buttocks, the hips, the inner knees, and the heels. Pressure injuries may also form in places where the skin folds over itself.
Keeping this in consideration, How do bony prominences prevent pressure ulcers?
In bed, body parts can be padded with pillows or foam to keep bony prominences (areas where bones are close to the skin surface) free of pressure. Place a pillow between the knees while sleeping on your side to prevent skin-to-skin contact and increase air circulation between your legs.
Which of the following areas is at a higher risk of skin breakdown?
Without proper care, this reddened area may develop into an opened wound. Incontinence, back of mobility and poor blood circulation are factors that place a resident at a higher risk for skin breakdown, or pressure ulcers.
- reddened or darkened areas.
- any change in the color of the skin.
- raised or hardened areas.
- warm areas felt near a red, dark, raised or hardened area.
Start appropriate preventative action (see recommendations 1.1. 1 – 1.1. 17) in adults who have non-blanching erythema and consider repeating the skin assessment at least every 2 hours until resolved.
If you're lying on your back, place a pillow under your lower calves to lift your ankles slightly off the bed. Sit upright and straight when sitting in a chair or wheelchair. This allows you to move more easily and help prevent new sores.
- part of the skin becoming discoloured – people with pale skin tend to get red patches, while people with dark skin tend to get purple or blue patches.
- discoloured patches not turning white when pressed.
- a patch of skin that feels warm, spongy or hard.
- pain or itchiness in the affected area.

Stage 1 sores are not open wounds. The skin may be painful, but it has no breaks or tears. The skin appears reddened and does not blanch (lose colour briefly when you press your finger on it and then remove your finger).
- Stage 1. The skin isn't broken, but it's discolored. ...
- Stage 2. There is breakage in the skin revealing a shallow ulcer or erosion. ...
- Stage 3. The ulcer is much deeper within the skin. ...
- Stage 4. Many layers are affected in this stage, including your muscle and bone.
Stage 1 pressure injuries are characterized by superficial reddening of the skin (or red, blue or purple hues in darkly pigmented skin) that when pressed does not turn white (non-blanchable erythema). If the cause of the injury is not relieved, these will progress and form proper ulcers.
However, it can take anywhere from three months to two years for a stage 4 bedsore to properly heal. If wound care for the stage 4 bedsore cannot be improved, the long-term prognosis is poor.
- Stage 1. The area looks red and feels warm to the touch. ...
- Stage 2. The area looks more damaged and may have an open sore, scrape, or blister. ...
- Stage 3. The area has a crater-like appearance due to damage below the skin's surface.
- Stage 4. The area is severely damaged and a large wound is present.
A pressure ulcer is a localized injury to the skin or underlying tissue, usually over a bony prominence, as a result of unrelieved pressure.
As the name suggests, DTI starts deep within tissue and does not usually become apparent until about 24–72 hours after the event that caused the tissue damage (Black et al, 2016).
Grade 3 or 4 pressure ulcers can develop quickly. For example, in susceptible people, a full-thickness pressure ulcer can sometimes develop in just 1 or 2 hours. However, in some cases, the damage will only become apparent a few days after the injury has occurred.
Clinically, separate identification of moisture lesions makes sense. They do not follow the same pattern as pressure ulcers. For example, they are not found over a bony prominence and can occur in areas of low pressure. There has been some debate about whether there can be a true definition of a moisture lesion.
Options that are antimicrobial or hydrocolloid, or that contain alginic acid, may be best. Dressings are available for purchase online. Use topical creams: Antibacterial creams can help combat an infection, while barrier creams can protect damaged or vulnerable skin.

Honey has been used as a medicine from the earliest ages. It has excellent astringent property and antimicrobial property, topical wound healing properties for sores, wounds and skin ulcers.
Find and correct the cause immediately. Test your skin with the blanching test: Press on the red, pink or darkened area with your finger. The area should go white; remove the pressure and the area should return to red, pink or darkened color within a few seconds, indicating good blood flow.
A skin assessment should include an actual observation of the entire body surface, including all wounds*, inspection of hair, nails, skin folds and web spaces on hands and feet, systematically from head to toe.
There are five key areas to note during a focused integumentary assessment: color, skin temperature, moisture level, skin turgor, and any lesions or skin breakdown.
