Closure Rate of Chronic Wounds With Sinus Tract: Morphological and Pathological Classification
Summary: A prospective case series from Ruijin Hospital, Shanghai, published in Wounds, evaluated closure rates in **chronic wounds with sinus tracts (CWST)** classified by morphological and pathological features. Four subtypes were defined: simple CWST, morphologically complex, pathologically complex, and refractory. The study demonstrates how systematic classification can guide prognosis and therapy selection.
Key Highlights:
- Simple CWST had the highest closure rate (~85%).
- Morphologically complex CWST healed in ~70% of cases with extended follow-up.
- Pathologically complex CWST (e.g., associated with osteomyelitis or chronic inflammation) had closure rates below 50%.
- Refractory CWST showed the poorest outcomes, underscoring need for advanced reconstructive or adjunctive therapies.
- Authors recommend that morphological and pathological assessment become routine in chronic sinus-tract wound evaluation.
