On diabetic foot, wound healing, amputation prevention, and the merger of consumer tech with medical devices
A new systematic review finds that roughly one in three adults in remission after a healed diabetic foot ulcer develop a recurrent ulcer within 12 months — a risk comparable to several common cancers. Healing is the beginning of the next chapter, not the end of the story.
Nearly a Million Words Later: What 17 Years of DiabeticFootOnline Look Like in a Word Cloud I recently did something I probably should have done a long time ago. I pointed an AI at every single blog post on this site—all 3,835 of them—and asked it to show me what nearly two decades of writing... Continue Reading →
In the world of diabetic foot care, we often find ourselves at a crossroads when a patient presents with isolated toe necrosis. Traditionally, this meant an automatic ticket to the operating room (OR) for a conventional amputation surgery (CAS). But as operating rooms become increasingly crowded and resources stretched thin, we have to ask: is... Continue Reading →
In the journey to eliminate preventable amputations, we continue to look for ways to harness the body’s own regenerative potential. Our latest brief communication describes a significant “first” in the field: the application of fully automated tibial periosteal distraction (PD) for limb preservation. While it has long been understood that applying controlled “tension-stress” to tissue... Continue Reading →

Armstrong, DPM, MD, PhD, and the Southwestern Academic Limb Salvage Alliance (SALSA) has crossed a significant bibliometric threshold, surpassing 90,000 citations in peer-reviewed literature. According to Google Scholar, Professor Armstrong’s research now holds an h-index of 133 and an i10-index of 549, reflecting the... Continue Reading →
For patients battling both diabetes and cancer, even a small foot wound can carry devastating consequences. Chemotherapy, radiation, immunotherapy, and stem cell transplants all compromise immunity and circulation. Add diabetes to the mix, and the risk of diabetic foot ulcers (DFUs) and amputations rises dramatically. What’s more, even minor foot infections can force oncologists to... Continue Reading →
A newly published case series by our colleagues Yammine and colleagues in the International Wound Journal sheds light on a deceptively humble yet visually distinctive presentation in the diabetic foot: the “sausage toe.” Once thought rare, this bulbous, swollen toe is increasingly recognized as a clinical marker of underlying osteomyelitis. The study offers a thoughtful reappraisal of... Continue Reading →
GLP‑1 Receptor Agonists and Limb Outcomes: What a 645,000‑Patient Study Tells Us A nationwide retrospective cohort analysis published this week in Diabetes Care explores whether glucagon‑like peptide‑1 receptor agonists (GLP‑1 RAs) confer advantages over sodium–glucose cotransporter‑2 inhibitors (SGLT2i) for lower‑extremity events in type 2 diabetes. Led by Dr Tze‑Woei Tan, the investigation examined 645,121 individuals newly started on either drug class between... Continue Reading →
