Diabetic peripheral neuropathy is the most dangerous and most common complication of diabetes as it relates to foot health. When the nerves that detect pain, temperature, and pressure are damaged by chronically elevated blood sugar, the early warning system that protects the feet from injury is silenced. Wounds develop, deepen, and become infected without the patient’s awareness — leading to a cascade that accounts for the majority of non-traumatic lower extremity amputations in the United States. At Balance Foot & Ankle in Southeast Michigan, Dr. Tom Biernacki provides specialized diabetic neuropathy foot care designed to prevent this outcome.

Understanding Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy (DPN) results from damage to peripheral nerve fibers — particularly small unmyelinated fibers responsible for pain and temperature sensation, and larger myelinated fibers responsible for touch and proprioception. Chronic hyperglycemia damages the microvasculature supplying nerve fibers (endoneurial hypoxia) and causes advanced glycation end products that impair nerve function. The result is a symmetric, length-dependent (“stocking-glove”) pattern of sensory loss starting at the toes and ascending toward the knees. Motor neuropathy causes intrinsic muscle atrophy — loss of the small muscles that maintain toe alignment — leading to the characteristic claw toe and hammertoe deformities that create high-pressure points prone to ulceration.

The Danger of Painless Feet

A patient with severe DPN may step on a nail, develop a blister from ill-fitting shoes, or sustain a burn from a hot surface and feel nothing. The wound progresses from a superficial skin break to a deep ulcer, then becomes infected with bacteria, and may involve bone (osteomyelitis). A diabetic patient with an ulcer that reaches bone has a high probability of requiring amputation if treatment is delayed. This entire process can occur silently over days to weeks. The absence of pain is not a sign that everything is fine — it is the most dangerous sign that neuropathy is advanced.

What Diabetic Neuropathy Foot Care Involves

Comprehensive diabetic neuropathy foot care at Balance Foot & Ankle includes: annual comprehensive diabetic foot exam (Medicare-covered) with 10-gram monofilament testing for protective sensation, vibration threshold testing, vascular assessment (ankle-brachial index when indicated), and inspection of all skin, nails, and joint deformities. Routine nail care and callus debridement prevent pre-ulcerative lesions from progressing. Custom diabetic insoles (prescription in-depth insoles) redistribute plantar pressure away from high-risk areas. Medicare Part B covers one pair of therapeutic diabetic shoes plus three pairs of custom insoles annually for qualifying diabetic patients. Wound care for active ulcers, with biofilm debridement, offloading, and topical wound management, is provided for established patients. Patient education — daily foot inspections with a mirror, water temperature testing before bathing, prohibition on walking barefoot — is a core component of every visit.

Preventing Charcot Neuroarthropathy

Charcot neuroarthropathy is a devastating complication of severe DPN in which the bones and joints of the foot collapse due to impaired proprioception and inflammatory osteolysis. The patient typically notices a warm, swollen, red foot without a clear injury history. X-rays show fragmentation and dislocation of midfoot joints. Immediate non-weight-bearing and casting is essential to prevent the deformity from progressing to a rocker-bottom foot that is nearly impossible to shoe and highly prone to plantar ulceration. Dr. Biernacki is experienced in recognizing Charcot early, before the dramatic deformity develops, and initiating urgent offloading.
