Radiographic Anatomy of the Talus

Detailed radiographic anatomy of the entire talus bone has not been previously described in the literature. We used radiopaque wire markers to identify 17 articular and nonarticular anatomical landmarks of the talus. Standard radiographic views of the foot and ankle were obtained: lateral (foot and ankle); anteroposterior, mortise, medial oblique, and lateral oblique (ankle); and dorsoplantar, medial oblique, and lateral oblique (foot). The resultant two-dimensional images are correlated to the three-dimensional anatomical specimen, and normal radiographic anatomy is described. Additionally, useful radiographic views for each anatomical landmark are identified. Composite figures of each useful view are presented as a pictorial atlas.
