Abstract
Reconstruction of complex traumatic chest wall defects, particularly those complicated by necrotizing fasciitis (NF), requires a meticulous and individualized surgical approach. This case report describes the successful management of a 46-year-old male patient with post-traumatic NF involving the scapular region. After multiple surgical debridements and negative pressure wound therapy, definitive reconstruction was achieved using a chimeric trapezius muscle flap, providing both defect coverage and functional restoration. This case highlights the utility of the trapezius flap in managing challenging chest wall defects, particularly when alternative flap options are limited, and underscores the critical role of a multidisciplinary approach in the treatment of severe soft tissue infections.
