What Causes Foot And Toe Ulcers How Do You Get An Ulcer
There are many possible causes. The most common include:
- Neuropathy from diabetes.
- Peripheral arterial disease.
- Deformed toes.
- Walking in an odd way where you put too much pressure on one part of your foot or toe.
- Friction. Your foot or toe may rub against the toebox of your shoe.
Assess Wound With A Full Exam
The best treatments begin with a comprehensive exam with a full evaluation.
Generally, this will begin with a process called debridement, which involves removing all dead skin from the feet. Many foot ulcers hide under callused skin, so only debridement can expose the real wounds and help your doctor evaluate the extent of your injuries.
If your circulation is especially poor, your doctor may wait to perform debridement until a vascular physician is able to identify the source of poor circulation, such as a major clogging of the blood vessels, and perform the treatment or surgery necessary to boost circulation again.
Whether debridement occurs first or second in this process, it creates clean edges around the diabetic foot ulcer and encourages healthy tissue to grow.

Ways To Treat Foot Ulcers
If you are currently experiencing a foot ulcer or think you have a foot wound while diabetic, then its important to seek professional care as soon as possible. This is not a normal wound you can treat at home as foot ulcers go past skin level where you need a professional Podiatrist to treat the wound and see if there are any complications such as infection. The faster you get professional help, the more chances you have in treating your wound. Regular family doctors will usually refer patients with foot ulcers to a professional wound care center where they specialize in foot wounds such as a foot ulcer. A diabetic wound care specialist in California, such as the Wound Institute of America, can provide the most advanced diabetic wound treatment with the latest wound care technology. Your primary doctor can provide a referral for your treatment to be continued at a professional center.
Wet To Dry Dressing Or Simple Saline
This dressing has a good debriding action and helps in wound bed preparation. Wet-to-dry dressings are described in the literature as a means of mechanical debridement. It is very absorptive as well as adherent and one of the cheapest dressings used throughout the world, but requires frequent dressing change based on wound severity. Dressings should be moistened before removal to minimize any chance of bleeding. A gentle cleanser will minimize wound irritation and discomfort. When treating a granulating or epithelizing wound one should soak the dressing thoroughly with normal saline for five minutes to prevent trauma and heavy bleeding.

Preventing A Diabetic Foot Ulcer
Holistic treatment of the individual with diabetes can help treat the underlying health issues and not only promote faster wound healing but also minimize risk factors that may have contributed to the development of a diabetic foot ulcer. Good diabetic control and lifestyle modification include:
- Keeping blood glucose levels optimal.
- Good nutrition and eating habits.
- Reducing high blood pressure.
- No smoking.
Individuals with diabetes should be instructed to:
- Examine their feet daily with a mirror and to look carefully for fungal infections or any abnormality.
- Wash and dry feet at least once a day in lukewarm water , paying special attention to dry between the toes.
- Not use heating pads or put feet close to heaters.
- Always use footwear inside and outdoors.
- Use close-toed shoes if they can’t feel their feet.
- Always use socks and change them daily.
- Have their nails cut carefully straight across by a trained professional .
- Treat dry feet with lubricants containing urea or salicylates, but don’t apply between toes.
In addition, every patient with diabetes should have a comprehensive foot exam yearly. Along with a careful physical exam, health care professionals should reinforce best practices of diabetic foot self-care at each visit to make sure the individual understands the recommendations and importance of caring for their feet.
Wound Care Centers Can Help Foot Ulcer Patients With:
- Debridement: An innovative way to heal ulcer wounds is to remove dead skin and tissue around the wound for the body to continue healing the infected area.
- Wound Offloading: the best thing to do for a wound is to remove any excess weight and pressure to allow healing. This can be done with wheelchair use, crutches and specialized medical foot gear.
- Wound Dressing: There are specialized wound dressings that can go over the wound to heal with either special healing collagen or antibiotic medication to prevent infection. This will be wrapped within every visit to a wound care center.
- Hyperbaric Oxygen Therapy: One of the most highly underrated wound care treatments out there is hyperbaric oxygen therapy. Hyperbaric oxygen therapy is exactly what you hear, oxygen therapy while in a chamber. This is a normal use for foot ulcers and it is shown to heal wounds at a rate of 80% faster than regular treatment. Inside a Hyperbaric chamber you take in 100% oxygen towards the areas in your body that are oxygen deprived and help your body heal at a faster pace because of the oxygen concentration. This treatment also helps kill bacteria in these infected wounds.
- Wound Surgery: You can close the wound with surgery and improve blood flow to the area of any damaged veins or arteries with surgical revascularization.

Nonsurgical Treatment For Diabetic Foot Ulcers
To help a diabetic foot ulcer heal, doctors at NYU Langone clean and disinfect the area. If the ulcer is infected, your doctor prescribes antibiotics to clear it up and prevent it from traveling to a bone in the foot.
Your doctor can refer you to an NYU Langone vascular specialist for additional medication if you have lower extremity arterial disease, a condition that impairs blood flow to the legs and feet and can cause an ulcer to heal more slowly.
NYU Langone doctors recommend regular wound care for foot ulcers, as well as other therapies.
Treatment For Diabetic Foot Ulcers
If a diabetic foot ulcer does occur, its important to seek medical care as soon as possible this is not a wound you should attempt to treat at home on your own. The faster a foot ulcer is properly treated, the greater chance it will heal completely and without infection or complications.
A diabetic wound care specialist, such as the Wound Care Center at Harrington, can provide the most advanced and comprehensive diabetic wound treatment. Your primary care physician can provide a referral to the wound care center. Our Wound Care Center team will then continue working hand-in-hand with your doctor throughout the wound treatment process.

Etiology Of Foot Ulceration
The etiology of diabetic foot ulcers usually has many components.4,7 A recent multicenter study8 attributed 63 percent of diabetic foot ulcers to the critical triad of peripheral sensory neuropathy, trauma, and deformity. Other factors in ulceration are ischemia, callus formation, and edema. Although infection is rarely implicated in the etiology of diabetic foot ulcers, the ulcers are susceptible to infection once the wound is present. Many of the risk factors for foot ulcer are also predisposing factors for amputation, because ulcers are primary causes leading to amputation.5,7,9 Recognized risk factors for diabetic foot ulceration are listed in Table 1.4

How To Prevent Diabetic Foot Ulcers
The first line of defense in preventing diabetic wounds is to follow the guidelines recommended to keep the disease itself under control:
- Maintain healthy blood sugar levels through a healthy diet and by taking medications as instructed by your doctor.
- Keep your blood pressure within a healthy range.
- Avoid alcohol and tobacco.
You should also take measures to avoid causing sores or wounds on the feet:
- Never walk barefoot.
- Wear shoes that fit properly and dont rub the skin.
- Wash your feet daily with mild soap and lukewarm water to prevent the buildup of bacteria on the skin, which can cause infection even in the tiniest skin breaks.
Because a loss of sensation in the feet may mean theres no pain felt even when an ulcer is present, its also extremely important for those with diabetes to regularly check for any foot sores or skin irritation. This way, the ulcer can be properly treated as early as possible.
Proliferation Of Tissue Resident Cells Is Crucial For Wound Closure
Wound closure requires reconstruction of the dermis before epithelial coverage by migratory basal keratinocytes can take place . This stage requires the reconstruction of the three-dimensional collagen structure of the dermis upon which subsequent cell populations are located. Therefore, fibroblasts and myofibroblasts are considered central players in this process . Their function is also supported by wound-resident macrophages, mast cells, and lymphocytes, in VEGF and TGF- dependent mechanisms . Importantly, this process is also closely associated with neovascularization of the wound bed, providing crucial nutrient and oxygen supplies to the healing site . M2 macrophages additionally support wound angiogenesis by direct and indirect mechanisms . Interestingly, these activities are similar to those observed in tumor-associated macrophages, as recently discussed elsewhere . Unfortunately, as mentioned before, in diabetic wounds, monocyte polarization towards M2 macrophages is inhibited, and pro-inflammatory polarization is promoted. Similarly, T2DM-impaired fibroblasts display a low activation level, decreased collagen deposition, and reduced paracrine signaling ability, including downregulation of TGF- pathway activation .

Data Extraction And Quality Assessment
Two independent authors extracted the following information from each study separately: Author, year of study, type of wound assessed, name of system, clinical use, parameters of wound assessed, measurement statistics, ability to integrate into Electronic Health Records or Electronic Medical Records other advantages and challenges. Quality of the included studies were assessed with the revised Methodological Index for NonRandomised Studies criteria10 . Descriptive studies and technical reports on the use of artificial intelligence were not included in the quality assessment as the use of MINORS criteria is not validated for these types of studies.
How Does Hbot Help Your Diabetic Wounds Heal
Oxygen can only make its way through the blood within red blood cells. Since the circulation problems associated with diabetes slow the movement of red blood cells, important tissues become deprived of oxygen.
Without enough oxygen, cells struggle to produce the energy they need to block bacteria, synthesize new collagen, or regenerate and repair after injury. This is why diabetic wound healing slows until it comes to a full stop. Inhaling the concentrated flow of oxygen provided through regular HBOT treatments makes it possible to overcome oxygen deficiencies and stimulate a more effective healing process.

How Can I Prevent Or Reduce My Risk Of Foot And Toe Ulcers
It may be possible to reduce your risk of getting ulcers, and even stop them from coming back. Try to:
- Manage your diabetes. If you have diabetes you should wear appropriate footwear and never walk barefoot.
- Every day, examine your legs as well as the tops and bottoms of your feet and the areas between your toes. Look for any blisters, cuts, cracks, scratches or other sores. Also check for redness, increased warmth, ingrown toenails, corns and calluses. Use a mirror to view your leg or foot if necessary, or have a family member look at the area for you. See a healthcare provider immediately if you notice any problems.
- Wear appropriate shoes and socks. Talk to your podiatrist about what you need.
Dressings And Topical Products
Alginate and other dressings
Alginate dressings are derived from seaweed and come in the form of calcium alginate or calcium sodium alginate or alginic acid. These alginate products form a highly absorbent gel that can absorb large volume of wound exudates to avoid skin maceration yet still maintain a moist environment. A Cochrane review and meta-analysis in 2013 showed no significant difference in ulcer healing with alginate products when compared with basic contact dressings or silver hydrocolloid dressings. Another systematic review in 2016 also found no difference in healing time between other synthetic active dressings and traditional dressings, including wet to dry saline moistened gauze, Vaseline gauze, and hydrofiber. As an exception, moderate-quality evidence suggested that hydrogel was more effective in healing DFUs.

Identifying Diabetic Foot Ulcers
Up to 25% of patients with diabetes will develop foot ulceration in their lifetime. This makes it important that health care professionals regularly check their patients with diabetes for signs of ulceration and identify risk factors. Patients who have had diabetes for an extended duration, those that have had previous ulcerations, those with peripheral arterial disease , those who have lost sensation in their lower extremities, and older adults are at particular risk. Patients presenting with DFUs generally experience pain, swelling, and odor emanating from the foot. Identifying these signs early on can help prevent complications and keep the wound from worsening.2
Diabetic Foot Ulcer Symptoms
Normally a wound or sore on the skin would cause pain. But the same loss of feeling in the feet that often contributes to the development of a diabetic foot ulcer means that theres often no pain associated with the ulcer. This can make it difficult for people to realize that an ulcer is even there in the early stages, when treatment is most effective.
Aside from pain, another sign to look for is discharge or drainage from the wound in the socks. Ulcers that have been present for some time and that have become infected may also cause an unpleasant odor.

When To See Your Doctor
If you begin to see blackened flesh around an area of numbness, see your doctor right away to seek treatment for an infected foot ulcer. If untreated, ulcers can cause abscesses and spread to other areas on your feet and legs.
At this point, ulcers can often only be treated by surgery, amputation, or replacement of lost skin by synthetic skin substitutes.
What Is A Diabetic Foot Ulcer
A diabetic foot ulcer is an open sore or wound that occurs in approximately 15 percent of patients with diabetes and is commonly located on the bottom of the foot. Of those who develop a foot ulcer, 6 percent will be hospitalized due to infection or other ulcer-related complication.
Diabetes is the leading cause of non-traumatic lower extremity amputations in the United States, and approximately 14-24 percent of patients with diabetes who develop a foot ulcer will require an amputation. Foot ulceration precedes 85 percent of diabetes-related amputations. Research has shown, however, that development of a foot ulcer is preventable.

Effectively Dressing Diabetic Foot Ulcers
Creating an optimal environment is essential to ensuring rapid healing and preventing complications. However, it can be challenging to effectively dress wounds located on the foot, particularly in cases of deformity or disease such as Charcot foot. To dress these wounds appropriately, health care professionals must often use non-traditional methods. Using best practices and more effective medical adhesive products can allow dressings to stay secure longer, even in unusual locations.2,4
Infection Control Infection in DFUs can lead to inflammation, delayed wound healing, gangrene, and amputation. To reduce the risk of infection and improve outcomes, health care professionals can use dressings that control bacterial load in the wound. Antibacterial agents such metronidazole gel and sisomicin can help control pathogens in the wound area.5
Wound Protection Because DFUs are located on the foot, they are more susceptible to additional injury than wounds in a less exposed location. This makes it important to choose a dressing that provides some amount of mechanical protection. Dressings that are secure and substantial can protect the wound area from additional damage. Using offloading techniques such as total contact casts and removable cast footwear can also help provide support the foot and prevent repetitive trauma.5
