Quick answer: Diabetic Foot Wound Care Guide Michigan is a common foot/ankle topic that affects many patients.

Diabetic foot wounds — ulcers, open sores, and blisters on the feet of diabetic patients — are the most common cause of non-traumatic lower limb amputation in the United States. Approximately 15% of diabetic patients will develop a foot ulcer during their lifetime, and 85% of diabetes-related amputations are preceded by a foot ulcer. The mechanism is the deadly combination of peripheral neuropathy (cannot feel pain), peripheral artery disease (poor wound healing), and susceptibility to infection. At Balance Foot & Ankle in Howell and Bloomfield Township, Michigan, Dr. Tom Biernacki, DPM provides urgent diabetic wound evaluation and comprehensive wound care.

Quick Answer: Diabetic Foot Wound Care

Any open wound on a diabetic foot requires same-day or next-day evaluation by a podiatrist — do not wait to see if it heals on its own. Clean the wound with saline or clean water, cover with a non-adherent dressing (not tight tape), keep weight off the foot if possible, and call immediately. A wound that is not at least 50% smaller within 2 weeks of appropriate treatment is at high risk for osteomyelitis (bone infection) and amputation. Red streaking up the leg, fever, or foul odor from the wound is a hospital emergency — call 911 or go to the ER immediately.

Why Diabetic Feet Are Uniquely Vulnerable

Three mechanisms combine to make diabetic foot wounds life-threatening:

• Peripheral neuropathy — Damage to sensory nerves from chronic hyperglycemia removes the pain warning signal. A diabetic patient may walk for days on a developing wound without feeling it. By the time the wound is noticed (often by a family member or at a routine appointment), it may already be infected or have eroded to bone.
• Peripheral artery disease (PAD) — Up to 50% of diabetic patients over 50 have significant PAD. Reduced blood flow to the extremities impairs the immune response, limits antibiotic delivery to infected tissue, and dramatically slows wound healing. Even minor wounds may not heal if perfusion is insufficient.
• Immune dysfunction — High blood glucose impairs neutrophil function (the primary cell that fights bacterial infection), making diabetic patients significantly more susceptible to deep tissue infections and osteomyelitis from what would be superficial wounds in non-diabetic patients.

Classifying the Wound: The Wagner Scale

• Grade 0 — Intact skin; risk factors present (pressure point, corn, callus, deformity); preventive treatment
• Grade 1 — Superficial ulcer; involves skin only; no infection; managed with off-loading and dressing changes
• Grade 2 — Deep ulcer; involves tendon or joint capsule; requires urgent evaluation; often requires debridement
• Grade 3 — Deep ulcer with osteomyelitis (bone infection) or abscess; requires hospital-level treatment; IV antibiotics; surgical debridement
• Grade 4 — Gangrene of part of the forefoot; surgical resection required
• Grade 5 — Gangrene of the entire foot; major amputation required

What to Do When You Find a Wound

Immediate steps:

• Clean with saline or clean water — do not use hydrogen peroxide or iodine, which damage the wound bed
• Apply a non-adherent dressing (Telfa, foam dressing) — do not use tight tape or waterproof coverings that trap moisture
• Stay off the foot as much as possible — a total contact cast or removable walker boot dramatically accelerates healing by reducing wound stress
• Call Balance Foot & Ankle immediately: (810) 206-1402 — same-day evaluation for diabetic wounds
• Go to the ER immediately if: red streaking up the leg (spreading cellulitis), fever, rigors (chills with shaking), foul odor with pus, or the wound has turned dark/black (tissue death)

Professional Wound Care: What Happens at Your Appointment

At Balance Foot & Ankle, diabetic wound evaluation includes: assessment of wound depth and extent (probing to bone if deep), vascular assessment (ankle-brachial index and/or toe pressure to determine if blood flow is adequate for healing), X-ray to screen for osteomyelitis and foreign body, and culture of wound bed to identify causative bacteria for targeted antibiotic selection. Wound care typically includes sharp debridement (removal of dead, necrotic tissue), specialized dressings, and total contact casting or removable walker boot for off-loading.

Off-Loading: The Most Important Treatment

Off-loading — removing weight from the wound area — is the single most important treatment for diabetic foot ulcers, regardless of wound care products used. A wound under continued weight-bearing stress cannot close because each step traumatizes the fragile healing tissue. Total contact casting (TCC) is the gold standard for plantar forefoot and heel ulcers, achieving healing rates of 70–90% within 6–8 weeks when compliance is maintained. Removable walker boots are an alternative but compliance must be monitored — patients who remove the boot at night defeat the purpose.

Osteomyelitis: When the Bone Gets Infected

Osteomyelitis (bone infection) complicates approximately 20% of diabetic foot ulcers and is the primary driver of amputation. It should be suspected in any wound that probes to bone on examination (the “probe-to-bone” test has 89% positive predictive value for osteomyelitis), any wound over a bony prominence, and any wound not healing after 2 weeks of appropriate treatment. MRI is the most sensitive imaging study for osteomyelitis. Treatment requires 6 weeks of IV or highly bioavailable oral antibiotics; infected bone must sometimes be surgically removed (resection) to achieve cure.

Prevention: Stopping the First Wound

• Daily foot inspection — Check all surfaces including between toes using a mirror; have a family member inspect areas you cannot see clearly
• Appropriate footwear — Extra-depth diabetic shoes with custom accommodative orthotics, Medicare-covered annually
• Never go barefoot — Diabetic patients should not walk barefoot at any time, including indoors
• Nail and skin care — Professional nail trimming; moisturize feet daily (not between toes) to prevent skin cracking
• Annual podiatry examination — Monofilament neuropathy testing, vascular assessment, and pressure point identification
• Blood sugar control — A1C <7% significantly reduces neuropathy progression; each 1% A1C reduction lowers microvascular complication risk by 25–35%

Frequently Asked Questions

When should I see a podiatrist?

If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).

What does treatment cost?

Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.

How quickly can I get an appointment?

Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.

More questions patients ask

How often should diabetics check their feet?

Diabetic patients should perform daily self-examinations of both feet, checking for cuts, blisters, redness, swelling, calluses, and temperature changes. Professional diabetic foot exams should occur at least annually, or every 3-6 months for patients with neuropathy, peripheral artery disease, or history of foot ulcers. Dr. Biernacki provides comprehensive diabetic foot care programs.

Why do diabetics have foot problems?

Diabetes causes peripheral neuropathy (nerve damage reducing sensation), peripheral artery disease (reduced blood flow), and impaired immune function. This combination means injuries go unnoticed, heal slowly, and are prone to infection. Approximately 15% of diabetics will develop a foot ulcer, and diabetic foot complications are the leading cause of non-traumatic amputation. Prevention through regular podiatric care is essential.

What are the signs of diabetic neuropathy in feet?

Early signs include tingling, burning, or numbness starting in the toes and progressing upward. Other symptoms include sensitivity to touch, muscle weakness, balance problems, and loss of reflexes. If you experience any of these symptoms, schedule an evaluation with Dr. Biernacki at 810-206-1402 for nerve conduction testing and a comprehensive neuropathy management plan.
