A new technique for removing intramedullary cement.

Treatment of infected long bone fractures or nonunions requires stability for bony union, yet retained implants can lead to persistent infection. Antibiotic cement intramedullary nails, in addition to external fixation, are commonly used to deliver intramedullary antibiotics in infected long bone fractures and provide temporary stability. However, the retrieval of these nails can result in debonding of antibiotic cement, which can require significant time and effort to remove. A variety of methods, including intramedullary hooks, reverse curettes, flexible osteotomes, and stacked guide rods, are commonly used to remove cement fragments. When these methods fail to allow access to the entire length of the canal, the Reamer Irrigator Aspirator system (Synthes, Paoli, PA) serves as an effective method for removing retained intramedullary cement. The surgical technique is described, and three cases illustrate the successful use of the Reamer Irrigator Aspirator system for removal of an antibiotic cement intramedullary nail.
