Time Does Not Heal All Wounds- The Dangers Of Normalizing Non Healing Wounds
Dr. G examines why "time heals all wounds" is dangerous for diabetic foot ulcers and explains when to reassess care. She highlights the four‑week benchmark, the importance of baseline measurements, and objective tracking of wound progress. The episode reviews common causes of non‑healing ulcers — persistent inflammation, poor perfusion, infection, inadequate offloading, devitalized tissue, and systemic factors — and stresses early vascular and surgical consultation when needed. Clear communication, multidisciplinary care, and timely reevaluation are essential to preserve limbs and restore function; time alone is not a treatment.

LIMBWatch Series: Kelly Laurel - Portable OR in a Backpack: How SurgiBox Is Saving Limbs Anywhere
LIMBWatch: Closing the Surgical Access Gap — How Portable Operating Room Technology Could Change Limb Salvage What if a sterile surgical environment could be created in minutes, virtually anywhere? In this episode of LIMBWatch by Diabetic Foot Files, Dr. G welcomes Kelly Laurel, President and CEO of SurgiBox, to explore the groundbreaking potential of the SurgiField System, a portable surgical environment developed through collaboration involving MIT, Harvard trauma surgeons, and the U.S. military. We discuss how this compact, backpack-portable technology uses HEPA-filtered air and positive pressure to create an ISO Class 7-equivalent surgical environment, potentially expanding access to procedures in settings where conventional operating room infrastructure is unavailable or difficult to access. Kelly shares lessons from nearly 25 years of military service, her personal experience waiting weeks for a brief hand surgery, and a remarkable demonstration in Jordan in which a vascular surgeon performed a diabetic foot ulcer debridement using the SurgiField System during a medical congress. For diabetic foot care professionals, the conversation explores a critical question: Could portable surgical technology help bridge the gap between recognizing a limb-threatening problem and delivering timely intervention? Dr. G and Kelly examine the consequences of operating room delays, the challenges of prioritizing foot and hand procedures, and the potential applications of portable surgical environments in wound debridement, limb salvage, dialysis access procedures, emergency care, and selected procedures in remote or resource-limited settings. The discussion also addresses the practical realities of bringing medical innovation to patients, including regulatory approval, insurance reimbursement, affordability, and the challenge of translating promising technology into sustainable clinical practice. From military medicine to global health, this episode challenges conventional thinking about where surgery can take place and how healthcare systems can respond when time is critical. Because in limb salvage, time is tissue. And when access to timely surgical care is the missing link, innovation may offer a new path forward. 🎙️ Guest: Kelly Laurel, President and CEO of SurgiBox 🎧 Host: Dr. Gabrielle Hutcheson Donaldson, DPM, CWSP, DABPM 🌍 Series: LIMBWatch by Diabetic Foot Files 🦶 Focus: Diabetic foot care, limb salvage, surgical innovation, global health, and access to timely intervention. Interested in exploring the SurgiField System or collaborating on potential clinical applications? Healthcare professionals interested in learning more or discussing potential pilot programs can contact Kelly Laurel at Kelly@SurgiBox.com. This episode explores emerging applications of portable surgical technology. Appropriate use depends on the procedure, clinical circumstances, applicable regulatory authorizations, and professional judgment.

LIMBWatch Series: Oxygen, Wound Healing & The Science of Saving Limbs with Dr. J.B. Shah
LIMBWatch: Oxygen, Wound Healing & The Science of Saving Limbs with Dr. J. B Shah What if a wound that refuses to heal is telling us something we have yet to recognize? In this episode of LIMBWatch, the diabetic foot surveillance series brought to you by Diabetic Foot Files, welcomes Dr. J.B Shah, an experienced physician leader in wound care, hyperbaric medicine, and limb preservation, with more than three decades dedicated to treating complex wounds and educating clinicians. Dr. Shah is the founder of TIMEO2 Healing Concepts and has held prominent leadership positions in organized medicine, including serving as President of the Texas Medical Association. His work emphasizes the critical role of oxygen in wound healing and the importance of evidence-based, multidisciplinary care. Together, we explore the science behind oxygen delivery, tissue hypoxia, and chronic wound healing, examining why some diabetic foot ulcers fail to heal even when the patient appears to have adequate blood flow. In this episode, we discuss: 🩺 The Oxygen–Wound Healing Connection: Why oxygen is essential for cellular function, collagen synthesis, immune defense, and tissue repair. 🩸 Hypoxia vs. Ischemia: Understanding the difference between inadequate blood supply and inadequate oxygen availability at the tissue level—and why this distinction matters when evaluating a non-healing wound. 🔬 The Hidden Biology of Chronic Wounds: How prolonged tissue hypoxia can impair cellular function, disrupt healing, and contribute to persistent wounds. 🫁 Hyperbaric Oxygen Therapy Explained: How systemic hyperbaric oxygen therapy works, how it differs from topical oxygen therapy, and why patient selection and clinical evidence matter. 📊 Selecting the Right Patient: The role of transcutaneous oxygen measurements, identifying potentially correctable causes of hypoxia, and evaluating whether a patient may benefit from oxygen-based therapies. 🦶 Beyond the Chamber: Why hyperbaric oxygen therapy is not a miracle cure—and why debridement, offloading, infection management, vascular assessment, glucose control, nutrition, and comprehensive wound care remain essential. ⚠️ The Importance of Early Intervention: Why even a small diabetic foot wound can become limb-threatening, particularly when neuropathy, infection, and vascular disease coexist. 🤝 The Power of Multidisciplinary Limb Salvage: Why timely referrals, coordinated care, and collaboration among podiatrists, vascular specialists, wound care clinicians, and other healthcare professionals can make a meaningful difference. 🤖 The Future of Wound Care: Dr. Shah shares his perspective on how artificial intelligence and point-of-care technologies could help clinicians identify wound complications earlier, stratify risk, and guide patients toward appropriate treatment pathways. 💡 LIMBWatch Rapid Fire: Dr. Shah answers important questions about the most overlooked factors in wound healing, the importance of individualized offloading, the biggest mistakes clinicians make, and the need to treat the whole patient—not just the wound. One of the most powerful messages from this conversation is that a diabetic foot ulcer should never be dismissed as a minor problem simply because it looks small. Early recognition, appropriate specialist assessment, and timely intervention can be critical to preventing complications and preserving a patient’s independence. Dr. Shah also challenges us to reconsider how healthcare systems approach amputation prevention. Rather than viewing every amputation as an inevitable outcome, we must examine opportunities for earlier intervention, better coordination, and improved standards of care. Because wound healing is never just about closing a wound. It is about understanding why healing has stalled, addressing the underlying causes, and remembering the person whose life is affected. A limb worth saving is a life worth protecting. 🎙️ About LIMBWatch LIMBWatch is the diabetic foot surveillance series brought to you by Diabetic Foot Files, dedicated to exploring the science, clinical insights, innovations, and interdisciplinary collaborations advancing wound care and limb preservation.

LIMBWatch Series- Jonathan Brocklehurst- Grandpa, Where Are Your Shoes? — The Question That Can Save Feet
Episode Summary Where Are Your Shoes? Turning Family Conversations Into Diabetic Foot Surveillance | LIMBWatch with Jonathan Brocklehurst In this episode of LIMBWatch, Dr. Gabrielle Hutcheson Donaldson sits down with Jonathan Brocklehurst MSc, MIRL, MRCPod, HCPC Registered Podiatrist, wound-care specialist, educator, and author of Grandpa, Where Are Your Shoes? for a powerful conversation about one of the most overlooked components of limb preservation: early observation and prevention. Jonathan shares the journey that led him from podiatry and amputee care to wound healing, health literacy, and ultimately writing a children’s book designed to make diabetic foot education accessible across generations. At the heart of the conversation is a deceptively simple question: “Where are your shoes?” Jonathan explore how footwear can provide clues about what is happening to the foot—from abnormal wear patterns and pressure to rubbing, deformity, instability, and potential sources of tissue breakdown. They discuss why people living with diabetes and neuropathy may not feel injuries developing, making daily visual inspection of the feet and shoes particularly important. But this episode goes far beyond footwear. Jonathan explains why children and family members can become important partners in diabetic foot surveillance without becoming amateur clinicians, and how simple conversations at home can help reduce stigma, isolation, and health-literacy barriers. The discussion explores the powerful relationship between grandparents and grandchildren—and how a child’s seemingly innocent question can open the door to conversations about diabetes, neuropathy, footwear, prevention, and seeking professional care. The conversation also tackles health equity and footwear affordability, emphasizing that effective diabetic foot prevention must account for social determinants of health and the realities of patients’ lives outside the clinic. In a rapid-fire finale, Jonathan addresses some of the biggest misconceptions surrounding diabetic feet, including the dangerous idea that “if it doesn’t hurt, it isn’t a problem.” He also shares practical advice on daily foot checks, footwear, hygiene, and avoiding potentially harmful DIY foot care. Ultimately, this episode asks us to rethink diabetic foot surveillance. It doesn’t always begin with advanced technology or a wound—it can begin with a question, a pair of shoes, a family conversation, and someone noticing that something has changed. Because sometimes, limb preservation begins at home. Where are your shoes? Check your feet. Check your shoes. Protect every step.

When Clinical Inertia Sinks Diabetic Foot Care
Dr. G uses the giraffe-in-quicksand metaphor to show how clinical inertia and tunnel vision quietly worsen diabetic foot ulcers. Clinical inertia isn't doing nothing—it’s doing too little: repeating dressings, documenting instead of investigating, or delaying referrals. She outlines four types of inertia (diagnostic, therapeutic, referral, cognitive), stresses multidisciplinary care, and gives clinical pearls: "stable" ≠ healing, always reassess diagnoses, address blood flow, infection, nutrition, and adherence, and prioritize curiosity, humility, and collaboration to prevent limb loss.
