A 45-year-old woman with type 2 diabetes presented with calcaneal osteomyelitis after being advised at another hospital that major amputation was the only treatment option. The infection involved the calcaneus, threatening both limb preservation and independent ambulation.

Limb-sparing surgery was performed with meticulous excision of all infected calcaneal bone until healthy, bleeding bone margins were achieved. Every effort was made to preserve the surrounding viable heel soft tissues, maintaining the specialized plantar heel pad that is essential for durable weight-bearing and long-term foot function.

The wound healed completely in approximately 3.5 months, without the need for major amputation.

This case demonstrates that even calcaneal osteomyelitis—traditionally considered one of the most challenging diabetic foot infections—can often be successfully managed with aggressive bone-sparing surgery and preservation of the heel soft tissues. Careful eradication of infection, while maintaining the native weight-bearing heel pad, allowed limb salvage and preserved independent walking despite a previous recommendation for amputation.
