LIMBWatch Series: Dr. Sukoff, Dr. Hanley & Dr. Warren - LIMBWatch: From Chronic Wound to Limb Preservation — The Science Behind Lavior
Diabetic Foot FilesShow Notes
Episode Summary In this episode of LIMBWatch, we go beyond the wound itself to explore the science, clinical challenges, and innovations shaping the future of limb preservation. We are joined by the team behind Lavior, including biomedical scientist and Chief Scientific Officer Dr. David Warren, wound care and hyperbaric medicine specialist Dr. Hanley, wound care podiatrist Dr. Sukoff, and National Sales Director Ashlyn Tapley. The conversation explores how Lavior was inspired by the healing properties of Inula viscosa, a medicinal plant with centuries of traditional use, and how the company developed a bioengineered hydrogel designed to address key challenges in chronic wound healing. We dive into the inflammatory phase of wound healing, antimicrobial and anti-inflammatory activity, bioactive compounds, wound-bed preparation, diabetic foot ulcers, surgical wounds, burns, pressure injuries, venous ulcers, and other complex wounds. The discussion also examines how Lavior is being used alongside negative pressure wound therapy, collagen, alginate, skin substitutes, PRP, total contact casting, and other wound-care modalities. Importantly, this episode goes beyond any single product. We discuss the fundamentals that remain critical to limb preservation: early intervention, vascular assessment and revascularization when necessary, meticulous wound-bed preparation, infection and biofilm management, moisture balance, and—perhaps most importantly—offloading. The episode also explores where wound care may be headed over the next decade, including new Lavior formulations incorporating collagen and calcium alginate, and the growing need for clinicians who understand chronic wounds and amputation prevention. And in one of the episode’s most memorable moments, Dr. Hanley shares a powerful message for people living with diabetes: “You can either have diabetes, or it can have you.” From the science of chronic inflammation to the human impact of amputation, this episode asks an essential LIMBWatch question: How early can we intervene—and what can we do differently to preserve the limb before the wound becomes a life-changing event? Episode Description Chronic wounds don’t just threaten skin—they can threaten mobility, independence, quality of life, and ultimately the limb. In this episode of LIMBWatch, we sit down with the Lavior team to explore a different approach to chronic wound healing and limb preservation. We discuss the science behind Lavior’s Inula viscosa-derived technology, its proposed antimicrobial and anti-inflammatory properties, the role of chronic inflammation in stalled wounds, and how the product is being incorporated into the management of diabetic foot ulcers and other complex wounds. We also tackle the clinical realities that matter beyond any dressing: early intervention, wound-bed preparation, vascular status, offloading, infection control, and multidisciplinary limb-salvage care. From diabetic foot ulcers and surgical wounds to ischemic wounds, pressure injuries, burns, and difficult-to-heal wounds, this conversation examines where innovation may fit into modern wound care—and where the fundamentals of limb preservation remain non-negotiable. Because saving a limb doesn’t start at amputation. It starts much earlier. 🎙️ LIMBWatch | Diabetic Foot Files This episode is for educational purposes and does not constitute medical advice or an endorsement of any specific product.

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.

She emphasizes assessing perfusion, infection, anatomy, and pressure before sharp debridement, and stresses that the right instrument, judgment, and team-based care are essential for limb salvage.
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
