Abstract (original English)

Background The treatment of complex wounds remains a challenging aspect of reconstructive surgery, given their diverse nature and the frequent need for high-level surgical procedures. Standard treatment with flap coverage can achieve many goals; however, it is not without difficulties, including technical complexity, extended recovery times, donor site morbidity, and vascular complications, particularly in non-optimized patients. Acellular extracellular matrices, such as porcine urinary bladder matrices, have emerged as an alternative approach to support wound healing without the risks of high-level reconstruction. Urinary bladder matrix provides an extracellular matrix scaffold that supports intrinsic tissue regeneration mechanisms, allowing for stable, well-vascularized wound bed formation. Methods This retrospective case series examines the outcomes of urinary bladder matrix for the treatment of complex wounds in 21 patients deemed high-risk or unfavorable candidates for surgical management with local or free flap techniques. The patients were treated by 2 surgeons at 2 separate level 1 trauma centers from October 2019 through June 2022. Urinary bladder matrix was the primary wound management modality with serial wound debridement, matrix reapplication, and subsequent wound care tailored to each patient until definitive, stable coverage. Results In all cases, urinary bladder
