Abstract
We report the case of a 71-year-old woman who sustained an intertrochanteric fracture after a simple fall. She initially underwent gamma nail fixation; however, implant failure and deep infection led to multiple revision surgeries. Despite prolonged antibiotic treatment, the infection persisted for eight months, making hardware removal necessary. To maintain stability while treating the infection, we used a custom-made, antibiotic-loaded cemented dynamic hip screw (DHS). This device was fabricated using a specially designed silicone mold. After two months, the infection cleared, allowing definitive reconstruction with a long-stem arthroplasty. The patient recovered well, regained function, and showed no signs of recurrent infection. This case highlights the challenges of managing recurrent implant failure and deep infection in intertrochanteric fractures. Furthermore, the use of cost-effective, reusable silicone molds for fabricating antibiotic-loaded implants appears to be a promising technique for orthopedic infection management.
