Brief Summary
The retrospective trial is observational, intended to stand alone, complement and integrate data collected in ongoing clinical studies to aid in establishing payor coverage in the United States (U.S.) for Cellution Biologics allograft products with real-world evidence to support the clinical adoption in patients to manage chronic or surgical wounds.

- Wound surface area is greater than 1cm2 at initial assessment.
- Clinical documentation of wound treatment.
You may not qualify if:
- AmchoPlast dHPT product was not applied to wound.
- HbA1C \>12%.
- Presence of active osteomyelitis.
- Concurrent treatment for malignant disease.
- Use of other advanced biologics during treatment period.
