A 77-year-old patient with diabetes mellitus presented with a necrotic lower leg ulcer accompanied by severe surrounding inflammation, edema, and soft-tissue infection. The combination of tissue necrosis, infection, and swelling created an unfavorable environment for wound healing and increased the risk of progressive tissue loss.

Serial surgical debridements were performed to remove all necrotic and devitalized tissue until healthy, bleeding margins were obtained. Treatment was combined with systemic antibiotic therapy, diuretic treatment to reduce edema, and compression bandaging to improve local tissue conditions and promote healing.

The infection and inflammation resolved progressively, edema was successfully controlled, and healthy granulation tissue developed, leading to progressive wound healing.

This case demonstrates that successful healing of complex diabetic leg wounds often depends on a comprehensive multidisciplinary approach, combining meticulous surgical debridement with infection control, edema management, and compression therapy rather than surgery alone.
