The investigators compare negative pressure wound therapy (NPWT) using the PICO 7 system versus professional wound debridement alone in adult orthopedic patients with acute, non-infected wound dehiscence or diabetic foot ulcers. Patients are randomized 1:1 to either PICO therapy (minimum 7 days, up to 42 days) or standard wound care (professional debridement without NPWT). The primary outcome is wound closure without surgical revision at Day 42. The trial is stratified for diabetic foot ulcers to enable subgroup analysis.
