A novel technique for surgical treatment of diabetic calcaneal osteomyelitis: Trabecular calcaneal instillation technique

Abstract

Negative Pressure Wound Therapy with instillation (NPWTi) is widely used for managing various wound types, including acute and chronic infections, soft tissue injuries and surgical wounds. However, there is a lack of large-scale, controlled studies specifically assessing the efficacy and safety of NPWTi in diabetic calcaneal osteomyelitis. This study aims to evaluate the effectiveness of the Trabecular Calcaneal Instillation technique, a novel surgical approach utilizing NPWTi for the management of diabetic calcaneal osteomyelitis. We implemented the Trabecular Calcaneal Instillation technique, which involves creating deep tubular cavities within the calcaneus and applying NPWTi. This approach was assessed in a cohort of 15 patients with diabetic calcaneal osteomyelitis. Key outcomes measured included wound healing rates, patient comfort and incidence of amputation. Preliminary findings indicate that the Trabecular Calcaneal Instillation technique significantly improved wound healing rates and patient comfort compared to traditional methods. It further allowed for the avoidance of amputation in 13 patients. The Trabecular Calcaneal Instillation technique shows advantages over traditional treatments for diabetic calcaneal osteomyelitis. Further research is necessary to confirm these findings and establish the technique's efficacy and safety in broader clinical practice.
