Computerized fluoroscopic-based navigation-assisted intramedullary nailing.

Intramedullary nailing, a fixation method commonly used for most diaphyseal fractures, relies heavily on fluoroscopy and delivers a significant amount of radiation to both patient and surgical team. Fluoroscopy-based computerized navigation enables accuracy in implant placement and minimizes soft-tissue dissection while reducing radiation. Navigation facilitates intramedullary nailing in determining entry-point location, insertion of locking and blocking screws, and nail and screw length measurement. We refer to our preliminary experience with 150+ cases to describe the technique of navigation-based intramedullary nailing and its various applications.
