Welcome to the Diabetic Foot Files Podcast and the LIMBWatch series — where diabetic foot surveillance, wound intelligence, prevention science, and limb preservation come together. I’m Dr. G / Dr. WoundPicasso aka Dr. Gabrielle Hutcheson Donaldson, podiatrist and wound care specialist, and I’m here to educate, empower, and guide you through the evolving world of diabetic foot care.

From wound healing and pressure injuries to surveillance systems and amputation prevention, we break down the science, challenge the myths, and share strategies that help save limbs and improve lives. Whether you’re a patient, caregiver, clinician, or healthcare professional, this is your destination for diabetic foot education, prevention, and preservation.

So let’s dive in — because when you take care of your feet, they take care of you.

Latest Episodes:

Auto Amputation and Demarcation- When the Body Cuts You Off: Understanding Auto-Amputation Jan 18, 2026

Show notes

In this episode Dr. G explains auto-amputation — when severely ischemic tissue becomes irreversibly necrotic, the immune system walls it off (demarcation), and the dead segment desiccates and may spontaneously detach. You’ll learn the step-by-step mechanisms from loss of blood flow and ATP depletion to fibro-inflammatory border formation and bone resorption.

We also cover why demarcation is not healing, how infection can convert dry gangrene to dangerous wet gangrene, and when urgent vascular care is needed to prevent limb loss or life-threatening complications.

Wheelchair Wounds: How Sitting Can Cause Diabetic Foot Ulcers Jan 17, 2026

Show notes

This episode explores why wheelchair-bound diabetic patients are at high risk for foot ulcers despite not walking. It explains how static pressure, neuropathy, contractures, and poor positioning concentrate force on the heels, lateral toes, and dorsal toes, leading to deep, hard-to-heal wounds.

Dr. G covers common ulcer sites, pressure-mapping thinking, prevention strategies (heel offloading, padded foot plates, AFOs, daily inspection), the role of caregivers, and practical tips for limb salvage and early detection.

Talking Dirty With Me - Wound Care Edition- The Clinically Candid Wound-Care Language That Saves Limbs Jan 16, 2026

Show notes

Dr. G breaks down essential wound-care terminology and explains why precise medical language matters for diagnosis, treatment, and communication with colleagues. The episode covers types of cell death, infection descriptors, gas in tissues, depth and space terms, vascular terminology, biofilms, debridement techniques, and common board-style questions.

Listeners learn practical phrasing to replace vague descriptions (e.g., "purulent exudate" instead of "pus", "chronic limb-threatening ischemia" instead of "bad circulation") and how accurate documentation can improve care and limb salvage.

The Black Toe Manifesto -Black Toe, Big Stakes: How to Save Limbs — Ischemia vs Embolism vs Cholesterol Emboli Jan 15, 2026

Show notes

This episode explains why a "black toe" is usually a sign of systemic vascular failure and breaks down the three main causes—chronic digital ischemia, acute arterial embolism, and blue-toe (cholesterol) syndrome—covering how each presents, key distinguishing features, essential diagnostic tests, and immediate management steps.

Takeaway actions include calling vascular early, avoiding premature amputation, initiating urgent anticoagulation for embolism when indicated, providing supportive care for cholesterol emboli, and preventing future events through diabetes control, smoking cessation, lipid management, and careful vascular intervention.

Diabetic Foot Care in Pregnancy: Treating Two Lives at Once Jan 15, 2026

Show notes

Dr. G explains how pregnancy alters diabetic foot care and why you must treat maternal and fetal risks together. This episode covers stricter glucose targets in pregnancy, safest imaging (ultrasound, MRI without contrast), preferred local anesthesia (lidocaine without epinephrine), recommended antibiotics (e.g., clindamycin), and cautions on CT, gadolinium, and long-term silver or iodine dressings.

Key practical points include careful vascular and wound exams, prompt evaluation of puncture wounds and foreign bodies, multidisciplinary decision-making with obstetrics, and tailoring wound care and procedures to minimize fetal risk while managing maternal infection and ischemia.

Wound Farm: When Healthcare Rewrites the Rules Jan 15, 2026

Show notes

This episode uses George Orwell's Animal Farm as an allegory to examine how healthcare systems can prioritize profit, rules, and convenience over equitable wound care. Dr. G explains how delays, denial of vascular studies, and systemic bias lead to unnecessary amputations and worse outcomes for underserved patients.

He outlines practical wound-care commandments—vascular evaluation, offloading, infection control, prevention, and persistence—and urges clinicians and patients to choose limb salvage over quick amputation. The episode emphasizes endurance, patient advocacy, and treating every limb as if it belonged to someone you love.

Skin Gardening 101: Grow Skin, Don't Just Treat Wounds Jan 12, 2026

Show notes

Dr. Gabby (Dr. G) the Skin Gardener reframes wound care as "skin gardening," explaining how skin regenerates layer by layer and why diabetic foot ulcers reflect a breakdown of the body’s ecosystem. She covers history, skin anatomy and cell roles, how diabetes disrupts healing (neuropathy, ischemia, infection), and why the basement membrane, fibroblasts, and perfusion are essential.

Practical takeaways include the core needs for growth: oxygen and perfusion, offloading and mechanical protection, moisture balance, debridement, and replacing missing signals. She also previews future tools—stem cells, bioengineered skin, and personalized therapies—to cultivate better healing outcomes.

De Motu Cordis- Motion Is Life: How William Harvey Revolutionized Circulation Jan 11, 2026

Show notes

Dr. G traces William Harvey's discovery of blood circulation and shows how it transformed medicine and modern wound care.

The episode explains why movement, pressure, and vascular health are essential for healing diabetic foot ulcers and outlines clinical approaches—revascularization, exercise, offloading, and glycemic control—that restore circulation and save limbs.

Bones Always Tell the Truth: Mastering Bone Scans for Diabetic Feet Jan 08, 2026

Show notes

This episode explains bone scans as functional, nuclear medicine tests that reveal bone metabolism—blood flow, inflammation, infection, and repair—often before structural imaging shows changes.

Learn the three phases (flow, blood pool, delayed), how osteomyelitis typically lights up all phases, pitfalls like Charcot foot and ischemia, and advanced options (SPECT‑CT, labeled white blood cell scans, PET) that improve diagnosis and guide limb‑salvage decisions.

Skin Substitutes Part II : Skin substitutes trademark names , Every Indication, Every Mistake (Part 2) Jan 08, 2026

Show notes

In this episode we break down skin substitutes for diabetic foot ulcers: how they work biologically, why they are not interchangeable, and common errors clinicians make.

We review major categories and examples (bioengineered cellular grafts like Apligraf and Dermagraft; human dermal matrices like AlloDerm and GraftJacket; placental/amniotic products like EpiFix and Grafix; xenografts such as Integra; and synthetic matrices like OASIS), plus inclusion/exclusion criteria.

Practical application rules are emphasized: sharp debridement to bleeding tissue, infection control, optimized perfusion, strict offloading, proper dressing, and documentation. Stop after 2–3 failed applications and remember grafts are tools—not cures.
