A pressure ulcer results when there is localized damage to the skin and underlying tissue as a result of compression between a bony prominence and an external surface. Damage is caused by the forces of pressure, shear, and friction acting individually or in combination with each other.

Pressure ulcers, previously termed decubitus ulcers, are also commonly referred to as pressure sores and bed sores. Common sites for pressure ulcer formation are the sacrum, over the ischial tuberosity, the trochanter, and the calcaneus.

Other locations are the elbow, ankle, scapula, and the occiput. However, the most common sites are the sacrum and the heels. Pressure ulcers affect from 1. Pressure ulcers occur more commonly in certain subsets of patients, such as elderly individuals ie, those over the age of 70 , patients who have had surgery for hip fracture, and patients with spinal cord injury. Patients in nursing homes or assisted living facilities or who are otherwise hospitalized are at increased risk for developing pressure ulcers.

Pressure ulcers are classified according to the extent of tissue damage per the National Pressure Ulcer Advisory Panel:. Dark Skin Considerations: Erythema can be subtle in darker skin and may appear as a slightly different color, or the skin may be slightly darker than normal.

Discoloration, warmth, induration, or hardness of skin may be the only signs of a stage I ulcer in people with darker skin tones. Deep tissue injury may also be difficult to detect in patients with more deeply pigmented skin.

Also, because a good amount of tissue is lost in the process, the affected area is closed by transplanting tissue from other parts of the body in a procedure called flap or skin graft surgery.

Pressure ulcers develop in 4 stages. In stages 1 and 2, surgery is not usually required. In fact, the ulcer can be treated by debridement, which is the removal of dead tissue from a wound, such as a pressure ulcer or burn. However, stages 3 and 4 ischial pressure ulcers are more difficult to treat and will require surgery.

The surgical excision of an ischial pressure ulcer is recommended for people with stages 3 or 4 of the condition. Those with early stages do not require surgery but are still closely monitored to prevent the condition from progressing. A combination of the above components will lead to a skin injury, which usually starts small.

However, as the break in the skin grows larger and becomes infected, a pressure ulcer develops. If the condition is not treated in the early stages, the pressure ulcer will continue to grow and affect the bone. To treat the condition, the surgeon will remove dead tissue as well as a part of the affected bone.

After removing the affected parts, the wound is closed. To do so, the surgeon will perform graft or flap surgery. Skin grafts can be performed when only a small amount of tissue has been affected by the pressure ulcer. If a larger amount of tissue and bone needs to be removed, the surgeon will perform myocutaneous flap surgery.

The procedure involves removing a sizeable amount of tissue and blood vessels from another portion of the body and transplanting it into the area where the pressure ulcer was removed. Patients can expect a relatively good chance of recovery. However, treatment should continue until the wound has fully healed. The procedure begins by having the patient lie face down on an operating table.

After the anaesthetic has taken effect, the surgeon will make an incision around the pressure ulcer.
