Interobserver Analysis of Standard Foot and Ankle Radiographic Angles

This study validates the previously documented normal angles using a significantly larger observer group as well as a greater number of analyzed angles. Additionally, this study reveals the tibio-second metatarsal angle on the calcaneal axial view is not a reliable radiographic angle for evaluation of foot and ankle deformity. Intraclass correlation coefficients were also analyzed, which displayed variability in measurements based on level of training, with residents being the most accurate, followed by attending physicians and then students. Foot and ankle radiographs are essential for surgical planning, and understanding normal versus abnormal is key before any surgical planning can be accurately performed.
