Catching Diabetic Foot Ulcers Before They Open: Using the Healing Trajectory Dashboard on…
product
How healing analytics extended to pre-ulcerative calluses lets clinicians intervene weeks before skin breaks — offloading earlier and reducing amputation risk.
Healing analytics is usually framed as a way to catch a stalled wound at week four. Applied to diabetic feet, the same trending logic can catch a callus that's becoming an ulcer weeks before the skin actually opens.
The pre-ulcerative window
Between "normal foot" and "open ulcer" there is a measurable window: a callus thickens, subcutaneous hemorrhage appears as a dark spot, surrounding erythema develops, temperature rises. Every one of those signals is trendable if you're capturing the same anatomic site consistently.
What the dashboard tracks on a callus
- Callus area over time — sustained growth is a red flag, not a plateau.
- Location-fixed serial images — stacked side-by-side, not scattered across visits.
- Erythema and periwound changes — visible in the trended imagery even before measurement changes.
- Time since last debridement — so the deformity/offloading plan can be reassessed on cadence, not by accident.
The intervention triggers
When a callus meets pre-ulcerative criteria, the dashboard prompts:
- Podiatry debridement within the week
- Reassessment of offloading (insole, felted padding, or total-contact cast)
- Footwear review
- Escalated visit frequency
Why it matters
Every diabetic foot ulcer that never opens is an amputation risk avoided. See the trending logic in Inside the Healing Trajectory Dashboard: Catching Stalled Wounds Before Week 4, and how it plugs into the broader diabetic foot care pathway alongside the Healing dashboard.
