Diabetic Foot Files

The below-the-knee amputation (BKA) is a common major limb loss in people with diabetes, resulting from a long pathway of neuropathy, vascular disease, biomechanical breakdown, ulcers, and infection. Modern amputation philosophy focuses on preserving the knee to maximize function, but BKA remains a marker of advanced systemic disease with significant morbidity and mortality.Preserving the knee improves mobility, energy efficiency, and prosthetic outcomes; yet prevention is crucial. Early screening, offloading, wound care, vascular assessment, and multidisciplinary limb-salvage teams—especially podiatrists working with vascular and infectious disease specialists—are key to stopping the progression that leads to amputation.

LIMBWatch Series | Dr. Paula DeJesus DPM, FACFAS, : The Future of Limb Salvage Through Minimally Invasive SurgeryIn this episode of the LIMBWatch Series on Diabetic Foot Files  sits with Dr. Lady Paula DeJesus DPM, FACFAS, DABPM, CWSP— a triple board‑certified podiatric surgeon and Section Chief at Yale New Haven Health Greenwich HospitalDr. Dejesus shares her remarkable journey into podiatric medicine and discusses the clinical decision-making behind complex diabetic foot infections, osteomyelitis, peripheral arterial disease, and limb preservation. She explains how minimally invasive surgical techniques are transforming diabetic limb salvage, including innovative approaches to treating calcaneal osteomyelitis while avoiding major amputations such as minimally invasive techniques like Avedis suction curettage.The conversation also explores the importance of multidisciplinary care, early vascular assessment, biomechanics, patient compliance, advanced imaging, regenerative medicine, and the compassionate communication needed to help patients understand amputation risk without losing hope.Whether you’re a podiatrist, wound care clinician, vascular specialist, student, or simply passionate about preventing amputations, this episode is filled with practical clinical pearls and inspiring insights from one of today’s leaders in limb salvage.In this episode you’ll learn:When to escalate from conservative care to surgeryThe role of vascular assessment in limb preservationWhy biomechanics is often the missing piece in wound healingModern approaches to diabetic foot osteomyelitisHow minimally invasive surgery is changing limb salvageThe value of multidisciplinary teams in reducing amputationsStrategies for improving patient compliance and communicationClinical lessons every young limb salvage specialist should knowIn this episode of Limb Watch, — shares real-world limb preservation strategies, including skin substitutes, and the importance of revascularization for diabetic foot infections.Diabetic Foot Files is dedicated to advancing diabetic foot care, wound healing, and amputation prevention through conversations with world-renowned experts in limb salvage.

Dr. G examines how diabetic toes and ulcers are rarely just wounds but visible warnings of neuropathy, poor circulation, infection, and gaps in care. She asks who is responsible for protecting the foot — the patient, primary care, podiatry, vascular, infectious disease, surgery, or nursing — and how fragmented referrals and delayed access can lead to a cascade ending in amputation.
The episode also explains hospital handling of amputated tissue, patients’ rights to their removed parts, and the future of limb preservation through surveillance technologies and coordinated responsibility to prevent avoidable loss.

This episode introduces edge trenching, a novel debridement technique developed by Dr. Igor Melnichuk that targets dysfunctional wound edges (epibolies, hyperkeratosis, rolled or fibrotic margins) to create a biologically active transition zone and promote epithelial migration.It explains the procedure, proposed mechanisms, clinical use—especially in diabetic plantar ulcers—how trenches are created and repeated, and emphasizes that edge trenching must be part of comprehensive care addressing perfusion, infection control, offloading, and underlying causes.

Dr. Giulia Baldazzi, a vascular surgeon, fellow and phd candidate researcher, shares her journey from UCSF to Italy and explores advances in perfusion assessment, revascularization, and limb preservation for diabetic foot care.
She discusses diagnostic innovations (PAT, MaxCORE, NIRS), the importance of early vascular referral and multidisciplinary teams, and practical strategies to prevent amputations and improve healing.

Actinomycosis is a rare, slow-growing filamentous gram-positive bacterial infection that can mimic cancer, tuberculosis, or chronic diabetic foot infections by producing woody fibrosis, interconnected sinus tracts, and characteristic yellow "sulfur" granules.Diagnosis requires deep tissue biopsy and careful anaerobic culture or histology; treatment is prolonged high‑dose penicillin (or alternatives if allergic) often combined with surgical drainage and debridement.

In this episode of Diabetics with Files, Dr. G explains liquid biopsies — blood tests that detect cell-free DNA and other molecular signals — and how they work.We explore how this technology could help detect infection early, identify harmful inflammation, predict a wound’s healing potential, and personalize treatment for diabetic foot ulcers.The episode also covers current limitations — cost, access, standardization, and need for clinical validation — and explains that liquid biopsies would complement, not replace, clinical exams and imaging.Ultimately, liquid biopsies could shift wound care from reactive to predictive and improve limb salvage in the future.

This episode explains how chronic wounds—especially heavily exudative and diabetic ulcers—act like metabolic drains, leaking proteins, growth factors, immune cells, electrolytes, and calories and impairing the body’ s ability to heal.
Listen for signs of protein loss (low albumin, persistent drainage, weight/muscle loss, delayed healing) and practical strategies to fight back: infection control, offloading, appropriate compression, nutrition optimization, and closing the wound to stop the ongoing resource loss.

LIMBWatch | Dr. David B. Alper – The Policy Behind Preventing Amputations
Why are so many lower extremity amputations still happening when the majority could be prevented?
In this powerful episode of LIMBWatch, Dr. Gabrielle Hutcheson sits down with nationally recognized limb preservation advocate Dr. David B. Alper, DPM, to explore the critical intersection of healthcare policy, reimbursement, advocacy, and limb salvage. Drawing on decades of clinical experience and legislative leadership, Dr. Alper explains why preventing amputations requires more than excellent medicine—it requires changing the healthcare system itself.
Together, they discuss the barriers clinicians face in obtaining early diagnostic testing, advanced wound care therapies, diabetic footwear, vascular imaging, and emerging technologies that could dramatically reduce limb loss. Dr. Alper also shares ongoing legislative efforts to improve access to care, simplify insurance requirements, expand diabetic foot protection programs, and strengthen multidisciplinary collaboration.
The conversation highlights the importance of early detection of peripheral artery disease (PAD) and chronic limb-threatening ischemia (CLTI), the role of advocacy organizations, and why clinicians, patients, and policymakers must work together to shift healthcare from reacting to amputations toward preventing them.
In this episode, you'll learn:
Why an estimated 85% of diabetic-related amputations may be preventable
The policy barriers limiting early PAD and CLTI diagnosis
How insurance reimbursement influences limb salvage decisions
Why diabetic footwear, vascular imaging, and preventative screening remain underutilized
The importance of multidisciplinary limb preservation teams
How clinicians and patients can become advocates for legislative change
Practical clinical pearls for identifying high-risk patients before limb loss occurs
Whether you're a podiatrist, vascular specialist, wound care clinician, primary care provider, healthcare administrator, policymaker, or patient advocate, this episode offers valuable insight into how policy decisions directly impact patient outcomes—and what can be done to change the future of limb preservation.
Because saving limbs starts long before the operating room—it starts with education, early intervention, and advocacy.
 

In this episode , one of the world’s most influential pioneers in limb preservation, Dr.David Armstrong DPM, MD, PhD Distinguished Professor of Surgery and Neurological Surgery and a Global Leader in limb preservation whose research has fundamentally changed how clinicians approach diabetic foot disease.
Dr. Armstrong shares the personal story that inspired his lifelong mission to prevent amputations, describing two unforgettable patients whose experiences taught him one of medicine’s greatest lessons—that the absence of pain can be more dangerous than pain itself.
Throughout the conversation, he explains why diabetic foot ulcers remain one of the most underestimated complications of diabetes, introduces the revolutionary concept of diabetic foot remission, and discusses why healing an ulcer is only the beginning of lifelong prevention.
Listeners will discover:
Why diabetic foot ulcers are a “silent and sinister syndrome”
The true meaning of diabetic foot remission and why recurrence is expected rather than failure
How annual foot screening could prevent countless amputations worldwide
Why multidisciplinary limb preservation teams reduce both amputations and mortality
The biggest unanswered questions surrounding diabetic foot infection
The future of wearable technology, smart insoles, smart socks, smart scales, and AI-powered home monitoring
How underserved communities can dramatically improve limb salvage with collaboration rather than expensive technology
Why the future of diabetic foot care depends on teamwork, innovation, and earlier intervention
Dr. Armstrong also reflects on the evolution of limb preservation over the past three decades, discusses the rapid advances in digital health and remote monitoring, and shares his vision of a future where preventable diabetic amputations become increasingly rare.
Whether you’re a podiatrist, vascular surgeon, wound care specialist, endocrinologist, nurse, therapist, researcher, student, or someone living with diabetes, this conversation offers invaluable insights from one of the architects of modern diabetic limb salvage.
 
Key Takeaway:
“Find a friend.” According to Dr. Armstrong, preventing amputations isn’t the work of one specialty—it takes interdisciplinary teams united by one mission: keeping patients walking and living healthier lives.
