Antibiotic-coated intramedullary nails have been popularized in recent decades for treating long-bone infections. They are especially useful in treating diaphyseal infections requiring stability, such as those involving fractures and nonunions. The nails are made by injecting antibiotic-impregnated polymethylmethacrylate or "cement" around a metal core using a silicone tube as a mold. There are a variety of techniques that can be used to customize the nail to the affected site. Antibiotic cement has long been demonstrated as an effective local antibiotic delivery system. It is able to elute high concentrations of antibiotics while having little systemic toxicity. Several case series have reported good outcomes using this technique, defined by bone union and infection control. Further research is needed to determine the amount of weight that can safely be transferred through the nail and to optimize antibiotic elution.
