| Abstract: | Fractures of the tarsal navicular are relatively uncommon, and generally are a result of acute trauma or chronic overload in the form of stress fractures. Their importance arise from being somewhat difficult to detect, and if missed can result in significant morbidity with midfoot arthrosis, especially since its complex anatomy and blood supply make the navicular susceptible to osteonecrosis. It is recommended to have a high index of suspicion along with the use of advanced imaging techniques to ensure fractures are not missed. The aetiology and current management concepts of tarsal navicular fractures are reviewed in order to guide optimal treatment for patients. Salvage options for delayed diagnosis and ongoing pain and functional limitation include arthrodesis of the midfoot which will also be discussed. |
