Aim: The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. Materials and Methods: Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the study. We used a scoring system to grade the scintigraphic abnormalities. The patients' symptoms and scintigraphic findings were recorded. Results: Though focally increased radiopharmaceutical uptake was observed in all symptomatic accessory naviculars, half of the asymptomatic accessory navicular bones had the same manifestations. The scoring system was of no value in differentiating symptomatic from asymptomatic accessory navicular bones. Conclusion: Bone scintigraphy is a sensitive but not a specific tool for diagnosing a symptomatic accessory navicular.
