Diabetic foot ulcers are open wounds on the feet that develop due to a combination of peripheral neuropathy (loss of protective sensation), peripheral arterial disease (reduced blood flow), and repetitive mechanical pressure — the triad that makes diabetes the leading cause of non-traumatic lower extremity amputation in the United States. At Balance Foot & Ankle in Southeast Michigan, Dr. Tom Biernacki provides comprehensive diabetic foot ulcer management focused on healing wounds, preventing infection, and reducing amputation risk for patients throughout the region.

Why Diabetic Foot Ulcers Are Serious

The combination of sensory neuropathy (inability to feel pain), motor neuropathy (intrinsic muscle weakness causing toe deformities and abnormal pressure distribution), and autonomic neuropathy (dry, fissured skin that breaks down more easily) creates conditions where small injuries — a blister from a shoe, a crack in dry skin, or pressure over a bony prominence — progress to open wounds without the patient noticing. Once open, reduced blood supply impairs wound healing and immune response. Early detection and expert wound management significantly reduce the risk of infection, osteomyelitis (bone infection), and amputation.

Wound Classification and Assessment

Dr. Biernacki evaluates diabetic foot ulcers using the Wagner Grading System and the University of Texas Wound Classification, which assess wound depth, presence of infection, and degree of ischemia. Vascular assessment (ankle-brachial index, toe pressures, or referral for vascular imaging) is critical for determining whether adequate blood flow exists to support healing. Probe-to-bone testing and X-rays assess for osteomyelitis. MRI is the gold standard for diagnosing bone infection when X-rays are inconclusive. This systematic assessment guides treatment decisions and establishes realistic healing expectations.

Treatment Approach

The foundation of diabetic foot ulcer treatment is offloading — removing the mechanical pressure that created and perpetuates the wound. Total contact casting (TCC) is the gold standard for plantar forefoot and midfoot ulcers; it distributes weight across the entire plantar surface and prevents patients from inadvertently loading the wound. Removable cast walkers (RCW) are an alternative when TCC is impractical, though patient adherence is lower. Sharp debridement of non-viable tissue and callus at each visit is essential — necrotic tissue harbors bacteria and prevents wound edge migration. Wound dressings are selected based on wound characteristics: moisture-retentive dressings for clean granulating wounds, antimicrobial dressings when surface bacterial burden is elevated, and negative pressure wound therapy (wound VAC) for larger wounds or post-operative defects. Antibiotic therapy is reserved for clinically infected wounds — not all diabetic ulcers are infected, and overuse of antibiotics promotes resistance. When vascular disease is limiting healing, vascular surgery referral for revascularization dramatically improves wound closure rates.

Advanced Wound Therapies

For wounds that fail to progress with standard care, advanced therapies may accelerate healing. Platelet-rich plasma (PRP) injections deliver concentrated growth factors directly to the wound bed. Bioengineered skin substitutes (dermal matrices, amnion-based products) provide a scaffold for new tissue growth. Hyperbaric oxygen therapy (HBOT) — in which the patient breathes 100% oxygen under pressure — increases oxygen delivery to ischemic wound tissue and is covered by Medicare for diabetic foot ulcers that have not responded to 30 days of standard care in patients with adequate vascular supply. Dr. Biernacki coordinates these advanced therapies as part of a comprehensive wound care plan.
