A 55-year-old woman with Type 2 Diabetes Mellitus presented with a diabetic foot plantar abscess complicated by fever and sepsis. A deep soft-tissue infection had rapidly progressed, creating an immediate threat to the foot and requiring urgent surgical intervention to control the infection.

Wide surgical incision and drainage were performed, followed by thorough debridement of all necrotic and infected tissue. The abscess cavity was fully explored, ensuring complete evacuation of purulent collections while preserving healthy tissue and promoting effective wound drainage.

The infection resolved rapidly, systemic sepsis subsided, and the wound healed completely within 2.5 months.

Early surgical source control successfully preserved the foot and prevented further spread of the infection, demonstrating that prompt and aggressive drainage of deep plantar abscesses is essential for limb salvage and can achieve complete healing without the need for amputation.
