Dr. Govindarajan Rajendran | Dr. Swaran Kumar M | Dr. Praveen K Sharma

Abstract: Background: Accessory navicular bone is one of the most common ossicles in the foot. Its prevalence is widely variable. These bones involve various mid-foot pathologies because of wide anatomic variations. It can cause medial foot pain, flattening the medial longitudinal arch, and impingement syndromes. The reported prevalence of accessory navicular is 4-21%. Objective: This study aimed to estimate the prevalence, anatomical variants, and distribution of accessory navicular bone of the foot in the radiograph by gender in the Indian population. Materials and methods: A retrospective study of 2068 radiographs of the foot (anteroposterior and oblique view) was performed. Used descriptive statistics for data analysis to know the prevalence of Accessory navicular bone. Results: 2068 radiographs were examined, in which 67.9 % of male and 32.1 % of female patients. In our study, the prevalence of accessory navicular is 16%, in which Type I (5.3%), Type II (9.1 %), and Type III (1.6%). Conclusion: Knowledge of accessory navicular of the foot helps avoid the common pitfall in clinical practice.
