It is the viewer’s responsibility to determine the educational value of this historical content.Intramedullary (IM) nailing has become a common method of treating long bone fractures. The indications for its use have expanded to include more proximal/distal fractures as well as more comminuted fractures. Though failure of an IM nail is uncommon, cyclical loading of the implant secondary to fracture nonunion will eventually lead to fatigue failure. The purpose of this video is to demonstrate one technique retrievinga broken IM implant as part of a nonunion repair. METHODS: Various devices and techniques have been developed and described for the removal of broken IM nails. Typically proximal segments have a manufacturer-specific extractor that engages the head of the nail. The distal fragment presents a more difficult task. One instrument, designed to remove the distal fragment, cannulates the nail and with a hooked tip and engages the tip of the implant as it is reverse extracted. RESULTS: In this video, we present a case of a broken tibial IM nail associated with a tibial fracture nonunion. We demonstrate the technique of retrieving the broken implant and exchange nailing for the tibial nonunion. A conical nail extractor for the proximal fragment and a long hook for the distal nail fragment are used to remove the remaining fragments. CONCLUSION: Removal of broken intramedullary implants can present a difficult challenge to the orthopaedic surgeon. Knowledge of tips and techniques for their removal will improve patient safety and decrease operative times.
