  🎙️ Diabetic Foot Files: Limb Watch with Dr. Shilpa Rajan Mulki What if some amputations could be prevented simply by recognizing the warning signs sooner? In this episode of Diabetic Foot Files: Limb Watch, Dr. Gabrielle sits down with Dr. Shilpa Rajan Mulki, a diabetologist and diabetic foot and wound-care specialist practicing in Nairobi, Kenya, for a powerful conversation about limb preservation, prevention, and the gaps that can stand between a patient and saving their limb. Dr. Mulki shares her personal journey into diabetic foot care and explains why multidisciplinary treatment changed the way she approaches complex wounds. Together, they discuss the warning signs of neuropathy and peripheral arterial disease, why so many patients never receive proper foot screening, and how small missed opportunities can eventually lead to devastating complications. The conversation goes beyond the wound itself—exploring offloading, infection and antibiotic misconceptions, nutrition, biomechanics, skin-tone differences in assessment, referral pathways, healthcare access, telemedicine, clinician education, and the importance of building multidisciplinary teams that actually work together. Most importantly, this episode asks a bigger question: Are we doing enough to prevent diabetic foot complications—or are we waiting until the limb is already in danger? Dr. Mulki message is one every person living with diabetes, caregiver, nurse, physician, and healthcare professional should hear: Look at your feet. Recognize the warning signs. Act early. Save the limb. Because limb preservation doesn't begin in the operating room. It begins with prevention

  LIMBWatch Series: Dr. Thomas Hardiman- 10-Gram Truth: How a Simple Monofilament Saves Feet 03.08.2026 42min

  Episode Title:The 10-Gram Test That Can Save a Limb: Understanding Monofilament Screening, Neuropathy & Prevention with Dr. Thomas Hardiman Episode Summary: What if one of the simplest tools in diabetic foot care could help prevent devastating complications before they happen? In this powerful episode of LIMBWatch on Diabetic Foot Files, Dr. Gabrielle Donaldson sits down with Dr. Thomas Hardiman, a podiatric surgeon with over 40 years of experience in foot and ankle care and a pioneer in diabetic foot screening through his work with medical monofilament technology. Together, they take a deep dive into the science, history, and clinical importance of the 10-gram monofilament examination — a simple yet powerful tool used to identify loss of protective sensation (LOPS) and help recognize patients at risk for diabetic foot ulcers and amputations. Dr. Hardiman reveals the fascinating story behind the development of the monofilament, from early sensory testing pioneers to the influence of Dr. Paul Brand’s groundbreaking work, and explains why prevention starts by “going upstream” rather than waiting until patients present with wounds. In this episode, you’ll learn: 🦶 How the 10-gram monofilament actually works and what is happening at the nerve level when sensation is lost🧬 How chronic hyperglycemia damages nerves through metabolic pathways, myelin injury, and impaired sensory signaling⚠️ Why neuropathy is not simply “numbness” — but the loss of the body’s protective alarm system🔍 Why a patient can have a normal monofilament exam and still remain at risk for ulceration🎵 The difference between monofilament testing, vibration perception testing, and tuning fork examinations📋 The correct technique, anatomical testing sites, and common mistakes clinicians make🦠 Why single-use monofilaments matter for accuracy and infection prevention👟 The importance of examining footwear and how a hidden foreign object can lead to a recurring ulcer🤖 How artificial intelligence may transform diabetic foot surveillance and help identify high-risk patients earlier❤️ Why patient education, daily foot inspections, and prevention remain some of the most powerful limb-saving interventions Dr. Hardiman shares unforgettable clinical lessons, including a patient whose heel ulcer repeatedly returned because a nail hidden inside his shoe was causing repeated trauma — a reminder that sometimes the most important diagnostic tools are simply looking, listening, and paying attention. He also challenges the healthcare community to rethink the phrase “silent epidemic,” explaining why diabetic foot complications are not silent and why calling them that may unintentionally create acceptance instead of urgency. His message to patients is clear: “Your feet should last a lifetime, and with proper care, they can.” This episode is a reminder that limb preservation does not always begin with the newest technology. Sometimes it begins with mastering the fundamentals, performing them consistently, and empowering patients before the first ulcer ever develops. Join us for an eye-opening conversation about neuropathy, prevention, screening, and the simple test that can help change the future of diabetic limb health. Key Takeaway Quote:“We don’t sell monofilaments. We partner in prevention.” — Dr. Thomas Hardiman 🦶 A 10-gram filament can change the future of a limb. Before a diabetic foot ulcer appears, there may be a silent warning sign: loss of protective sensation. Dr. Hardiman, Medical Director of Medical Monofilament, explains why proper monofilament testing matters — helping clinicians identify the “foot at risk” and take action before a small problem becomes a devastating complication.
