Why You Can't Just Glue a Diabetic Foot Ulcer Closed

In this episode Dr. G explains why tissue adhesives like cyanoacrylates (e.g., Dermabond) work well for clean, superficial, low‑tension wounds but are inappropriate for diabetic foot ulcers. Diabetic ulcers involve neuropathy, poor perfusion, infection risk, dead space, undermining and impaired healing biology that glues cannot fix.Key takeaways: adhesives only bond superficial skin edges and do not treat infection, necrosis, ischemia or structural problems; using glue can trap drainage and mask deeper issues; tissue glue may last days but is not a cure for complex diabetic wounds.
