Diabetic Foot Ulcers (DFU)
- Diabetic foot ulcers are open sores or wounds that are commonly located on the bottom of the foot. Other medical conditions, including peripheral arterial disease and neuropathy, lead to the development and prolonged healing of these ulcers. Diabetics have a 25% lifetime risk of developing a foot ulcer and these ulcers can lead amputations in diabetics.
- Venous ulcers (also referred to as stasis, insufficiency or varicose ulcers) are the result of malfunctioning valves in the vein, causing pressure in the veins to increase. These typically occur on the lower leg. The resulting high pressure in the vein causes blood to pool when it is not efficiently pumped back towards the heart (venous insufficiency). In addition, the increase in pressure stretches the vein walls, causing the veins to leak and the surrounding tissues to break down.
- Arterial leg ulcers occur because of poor blood supply to the legs due to a blockage or narrowing of the arteries in the leg (atherosclerosis). Without treatment of the underlying poor arterial blood supply, ulcers take a long time to heal or may never heal, which may lead to amputation.
- Pressure ulcers are injuries to skin and underlying tissue resulting from prolonged pressure on skin that covers bony areas of the body, such as the heels, ankles, hips and tailbone. People most at risk of pressure ulcers are those with a medical condition that limits their ability to change positions or those who spend most of their time in a bed or chair.
- Postoperative wounds are those wounds that occur after surgical procedures. Complications after surgery may include wound dehiscence (separation of the layers that were sewn together), infection, seroma (collection of fluid), or hematoma (collection of blood).
- Traumatic wounds are typically defined as cuts, lacerations or puncture wounds which have caused damage to both the skin and underlying tissues.
1st and 2nd Degree Burns
- Damage to the skin or other body parts caused by extreme heat, flame, contact with heated objects, or chemicals. Burn depth is generally categorized as first, second, or third degree. The treatment of burns depends on the depth, area, and location of the burn, as well as additional factors, such as material that may be burned onto or into the skin.
- Necrosis is the death of cells in living tissue caused by external factors such as infection, trauma, or toxins, which is almost always detrimental to the health of the patient and can be fatal. Necrotic tissue can delay wound healing, and it is often necessary for the dead or dying tissue to be removed before any progress towards healing can be made. When substantial areas of tissue become necrotic due to lack of blood supply, this is known as gangrene.
