Official Publication of the National Center for Trauma Research Trauma Monthly 2251-7464 31 2 2026 04 01 Development of a Novel Aantibiotic-loaded Cemented Dynamic Hip Screw Using Silicone Mold for Treating Infected Intertrochanteric Fracture: A Case Report 1750 1756 245959 10.30491/tm.2026.561246.1906 EN Ismaeil Garivani Department of Orthopedic Surgery, Khatam ol anbia Hospital, North Khorasan University of Medical Sciences, Bojnurd, Iran Negin Armide Student research committee, School of Medicine, Imam Ali Hospital, North Khorasan University of Medical Sciences, Bojnurd, Iran Mohamad Amin Younessi Heravi Department of Medical Physics and Radiology, North Khorasan University of Medical Sciences, School of Allied Medical Sciences, Bojnurd, Iran 0000-0002-7960-3095 Journal Article 2025 11 21 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.
