What is a Foot Ulcer?

On the most basic level, a foot ulcer is open sore on the feet, primarily on the bottom of the foot or toes.

8 Common Reasons Why Foot Ulcers Develop

• Uncontrolled Blood Sugar Levels: Elevated blood sugar levels can lead to the narrowing of blood vessels and stiffening of arteries. This restriction reduces blood and oxygen flow, which impairs the body’s natural ability to heal. As a result, when a foot ulcer develops, it may not heal effectively due to these complications.
• Nerve Damage: Nerve damage, often caused by uncontrolled diabetes, is a common issue for those living with the condition. Peripheral neuropathy, a type of nerve damage, can result in a loss of sensation and the inability to feel pain. This is particularly dangerous for diabetics, as they may not notice the presence of a foot ulcer or recognize when it has become severely infected.
• Poor Circulation: Our Dallas podiatrist highlights that diabetics are at an increased risk of developing peripheral arterial disease (PAD), which limits blood flow to the legs and feet. This poor circulation hinders the body’s healing process. Consequently, sores or wounds may develop into foot ulcers that fail to heal, potentially leading to severe complications or even amputation.
• Sedentary Lifestyle: A sedentary lifestyle, often linked to prolonged bed rest due to illness or injury, can further reduce blood circulation in the legs and feet for diabetics. This lack of circulation decreases the flow of oxygen-rich blood, significantly increasing the risk of developing foot ulcers.
• Weakened Immune System: Diabetes can impair the immune system, reducing the body’s ability to heal and regenerate new skin cells and tissue. As a result, diabetic foot ulcers may form and become infected if the immune system is unable to support proper healing.
• Trauma or Injury: Trauma or injury to the foot, such as cuts, scrapes, or blisters, can easily develop into foot ulcers if left untreated. In individuals with conditions like diabetes, reduced sensation due to nerve damage (neuropathy) can prevent them from noticing these minor injuries. When pressure is continuously applied to the wounded area through walking or wearing improper footwear, the injury fails to heal and worsens over time, increasing the risk of infection and ulcer formation. Early detection and proper wound care are essential to prevent minor injuries from escalating.
• Infections: Infections play a significant role in the development and progression of foot ulcers, especially in people with compromised immune systems or poor circulation. Bacterial infections can occur when a wound is exposed to contaminants, and without sufficient blood flow to deliver healing nutrients and oxygen, the body struggles to fight off the infection. For individuals with diabetes, high blood sugar levels can further weaken the immune response, allowing infections to spread rapidly. Untreated infections can result in severe complications, such as abscesses, tissue death, or systemic infection.
• Foot Deformities: Structural abnormalities of the feet, such as bunions, hammertoes, or high arches, can lead to uneven pressure distribution during walking or standing. These deformities create pressure points on specific areas of the foot, increasing the likelihood of skin breakdown and ulcer formation. For example, a bunion can cause excessive rubbing against shoes, leading to calluses, blisters, or open sores that may evolve into ulcers. Properly fitted footwear, orthotics, and timely treatment of deformities are key to preventing ulcers in individuals with foot abnormalities.

What is a Pressure Ulcer?

A pressure ulcer, or bedsore, is caused by prolonged pressure on a particular area of the skin. This type of ulcer is common among individuals who are bedridden, use a wheelchair, or have limited mobility. A pressure ulcer can develop anywhere on the body, including the feet. Common areas for a pressure ulcer to develop are the heels and soles of the feet.

Symptoms of a Pressure Ulcer

• Visible open wound
• Pain or tenderness to the touch
• Skin discoloration
• Swelling
• Warmth in the affected area

What is a Diabetic Foot Ulcer?

A diabetic foot ulcer is a sore on the skin of the foot that results from nerve damage or poor circulation due to diabetes. It most commonly develops around the toes and heels of the feet. Diabetic foot ulcers are extremely painful and dangerous since they can lead to severe complications if not treated. Complications include infections, amputation, and even death.

Those with diabetes are at higher risk of developing foot ulcers due to peripheral neuropathy or nerve damage, which can cause a decrease in sensation in the feet. If the person does not feel an injury to their foot, it can go undetected until it becomes a bigger problem. 

Symptoms of a Diabetic Foot Ulcer

• Open wound
• Drainage on your socks from the wound
• Redness or swelling
• Pain or discomfort
• Foul odor

Difference Between a Pressure Ulcer and a Diabetic Foot Ulcer

Pressure ulcers and diabetic foot ulcers are two types of wounds that can develop on your feet. They both can have severe consequences if not appropriately managed. There are several differences between the two types of foot ulcers:

• Cause: Pressure ulcers are caused by prolonged pressure on the skin and underlying tissues. Diabetic foot ulcers are a complication of diabetes.
• Location: Pressure ulcers often form on bony prominences, such as the heels of the feet. Diabetic foot ulcers are mostly found on the bottoms of the feet, toes, and sides of the feet.
• Appearance: Pressure ulcers have a distinct shape and can appear as a blister, open sore, or crater-like indentation. The surrounding skin may also be discolored or feel warm to the touch. Diabetic foot ulcers may be deep, with a callused edge, and the surrounding skin may have redness or swelling.
• Treatment: Treatment for both types of ulcers will depend on their severity and underlying cause. Pressure ulcers often require pressure-relieving devices, such as padding or cushioning, to reduce the amount of pressure on the affected area. Diabetic foot ulcers may require more advanced treatments, such as debridement and antibiotics, to treat or prevent infection, and surgery may be an option for more severe wounds.

What Does a Foot Ulcer Look Like?

A foot ulcer is usually characterized by a red crater-like wound often found near the toe or heel of the foot. Foot ulcers can vary in size and shape. In addition to the wound itself, there may be signs such as pain, swelling, discoloration, and warmth. As a foot ulcer worsens, there may be drainage and a foul odor, and black tissue may surround the wound.

If you notice any signs of a foot ulcer, seek medical attention immediately. The sooner you seek treatment from an experienced podiatrist, the more likely you are to prevent more serious complications such as infection or amputation.

5 Treatment Options for Patients With a Foot Ulcer in Grapevine

There are several different treatment options for patients with a foot ulcer in Grapevine, Keller, or anywhere in North Tarrant County, for that matter. Below, our experienced Grapevine podiatrist discusses the 5 most common treatments for foot wounds:

Off-Loading a Foot Ulcer

Off-loading is a crucial step in managing foot ulcers as it reduces pressure on the affected area, allowing the wound to heal more effectively. This can involve various methods, such as placing specialized padding over the ulcer to cushion and protect it from further irritation. Mobility aids like crutches help to avoid putting weight on the affected foot entirely. Additionally, braces or casts can be used to immobilize the foot and distribute pressure more evenly, while compression wraps can reduce swelling and promote circulation. The primary benefit of off-loading is that it minimizes repetitive trauma to the ulcer, creating an environment conducive to healing and reducing the risk of complications.

Medication for Foot Ulcers

Treating a foot ulcer often requires medication to address infections and support the healing process. When an infection is present, applying an antibiotic ointment directly to the ulcer, followed by covering it with a sterile dressing, helps prevent the spread of bacteria and promotes wound recovery. In more severe cases, oral antibiotics may be prescribed to combat systemic infections. These medications play a vital role in controlling bacterial growth, reducing inflammation, and preventing further complications, ensuring the ulcer has the best chance of healing without escalating into a more serious condition.

Cleaning a Foot Wound

Keeping the ulcer clean and dry is one of the most fundamental aspects of wound care. This involves gently washing the area daily with a mild soap and warm water to remove dirt, bacteria, and dead tissue, which can inhibit healing. After cleaning, the ulcer should be carefully dried and covered with a fresh, sterile dressing or bandage to maintain cleanliness and protect it from external contaminants. Proper cleaning minimizes the risk of infection, supports faster healing, and prevents the ulcer from worsening.

Debridement of a Foot Ulcer

Debridement, the process of removing dead or infected tissue from the ulcer, is essential for promoting recovery. Performed by a podiatrist using specialized tools, this procedure clears away necrotic tissue that can harbor bacteria and block the growth of healthy tissue. By exposing the healthy layers of skin and improving circulation to the area, debridement accelerates the healing process. Additionally, it reduces the risk of infection spreading and helps medical professionals better assess the condition of the wound, enabling more targeted treatments.

Surgery is an Option for Foot Wounds

When other treatments fail to heal a foot ulcer, surgery may be necessary to address the underlying causes. Surgical procedures can include correcting foot deformities such as hammertoes or bunions that place undue pressure on the ulcer. In some cases, shaving or removing problematic bone structures can help alleviate pressure points and improve alignment. Surgery can also address deeper infections that have reached the bone or other tissues. While surgery is more invasive, it offers the benefit of addressing the root cause of chronic ulcers, preventing recurrence, and significantly improving the patient’s quality of life by reducing pain and the risk of amputation.

Understanding The Stages of a Foot Ulcer

Stage 0: Pre-Ulcer Stage

At this initial stage, there are no visible open sores or ulcers on the foot. The skin appears intact and healthy, with no signs of damage or infection. However, individuals at this stage may experience conditions such as calluses, redness, or minor irritation, which can develop into ulcers if not addressed. Early preventive measures, such as proper footwear, regular foot inspections, and managing underlying conditions like diabetes, are essential to avoid progression to later stages.

Stage 1: Superficial Ulcer

At this stage, the ulcer is superficial, affecting only the outermost layers of the skin. The wound is shallow and does not extend into deeper tissues like tendons or ligaments. Conservative treatments, such as off-loading pressure from the affected area, cleaning the wound, and applying antibiotic dressings, are typically effective in promoting healing. Timely intervention is crucial to prevent the ulcer from deepening or becoming infected.

Stage 2: Deeper Ulcer

During this stage, the ulcer progresses beyond the outer layers of the skin and penetrates deeper tissues, such as ligaments, tendons, or even the bone or joint structures of the foot. The risk of infection increases significantly at this stage, making thorough cleaning, advanced wound care, and possibly the use of antibiotics critical to managing the condition. Without prompt treatment, complications like abscesses or systemic infections may develop.

Stage 3: Advanced Ulcer with Complications

In stage 3, the ulcer has severely impacted the deeper layers of the skin and underlying tissues. Complications such as abscesses, osteomyelitis (bone infection), or septic arthritis (infection in the joint) may be present. This stage often requires more aggressive treatment, including debridement of dead tissue, hospitalization for intravenous antibiotics, or imaging studies to evaluate the extent of infection. Surgical intervention may also be necessary to manage the ulcer and prevent further complications.

Stage 4: Localized Gangrene

At this stage, the presence of gangrene indicates tissue death, usually localized to the forefoot or heels. The affected area appears black or discolored and may emit a foul odor due to necrosis. Immediate medical attention is required, as gangrene poses a significant risk of spreading infection to other parts of the body. Treatment often includes surgical removal of the dead tissue and advanced therapies to improve circulation and control infection.

Stage 5: Extensive Gangrene

Stage 5 represents the most severe level, where gangrene has spread throughout the entire foot. The damage is extensive, and the risk of systemic infection or sepsis is high, posing a life-threatening situation. In most cases, amputation of the foot is the only viable option to save the patient’s life. Post-surgical rehabilitation and infection management are critical components of recovery, along with strategies to prevent future ulcers in the remaining limb.

Tips for Preventing Foot Ulcers

• Do a daily foot inspection to check for any signs of injury or abnormality.
• Take proper care of your feet, including washing and moisturizing your feet regularly.
• Avoid walking barefoot, and always wear socks to protect your feet.
• Wear shoes that fit correctly and are not too tight or rub areas of your feet.
• Keep your blood sugar levels under control.
• See a podiatrist at the first sign of a problem and for annual foot exams.
