BACKGROUND: Intramedullary implants have been used historically in long bone fractures with success. In recent years, a variety of intramedullary implants for the treatment of fibular fractures have been investigated. These various implants have not been assessed together in a cohesive manner. In this review, we assess implants used for intramedullary fixation of fibular fractures with respect to implant design and clinical results. METHODS: A comprehensive systematic literature review for intramedullary implants in fibular fractures was performed. All publications that assessed intramedullary fibular implants were reviewed. In total, 11 different intramedullary nails were found. Clinical results obtained from these studies were reviewed. RESULTS: The intramedullary implants used for fibular fracture fixation generally fell into one of 3 categories: an unlocked longitudinal strut, an implant roughly equivalent to a large screw, or a more traditionally locked intramedullary nail. Reported clinical results were generally good, although inconsistent outcome reporting greatly limited comparison between studies. Complication rates varied with the implants but were generally low. CONCLUSION: Intramedullary implants for fibular fracture stabilization have changed over the years to improve stability. Although clinical results are limited, data suggest that these implants are safe and can potentially approximate more traditional implants. LEVEL OF EVIDENCE: Level II, systematic review.
