Pressure sores after lower limb loss are areas of skin and tissue damage caused by constant pressure, rubbing, or pulling on the skin of the residual limb. They form when blood flow to the skin is reduced, which prevents the tissue from getting the oxygen it needs to stay healthy. This can happen from sitting or lying in one position for too long, moisture on the skin, or repeated friction. Early signs may include redness, warmth, or tenderness, and if not treated, these areas can turn into open wounds. Pressure sores can be painful, slow-healing, and limit daily activities. Prevention includes changing positions often, keeping the skin clean and dry, and checking the area daily for any changes. If a sore develops, it is suggested that you see a wound care specialist to relieve pressure, protect the area, and receive other appropriate treatment.

Understanding Pressure Sores, Pressure Ulcers, and Arterial Ulcers
Wounds that develop on the skin due to pressure or poor blood flow require careful attention. Pressure sores, also called pressure ulcers, form when constant pressure reduces blood supply to an area, often over bony parts of the body. This can happen in individuals who spend long periods of time sitting or lying down. Without relief of pressure, the skin and underlying tissue can break down, leading to an open wound.
Arterial ulcers develop for a different reason. These wounds are caused by reduced blood flow through the arteries, which limits the oxygen and nutrients needed for healing. They are often found on the feet or toes, and may appear as deep, painful sores with well-defined edges. The surrounding skin may feel cool, and healing can be slow without improving circulation.
From a wound care perspective, identifying the cause is essential. Pressure-related wounds require off-loading, which means reducing or redistributing pressure on the affected area. Arterial ulcers require evaluation of blood flow and may need medical intervention to improve circulation.
Proper care includes keeping wounds clean, protected, and monitored for signs of infection such as redness, swelling, drainage, or increased pain. Dressings are selected based on the condition of the wound and surrounding skin. Early treatment can help prevent complications and support healing.
