Design: Retrospective cohort.

Methods: The Defense Medical Epidemiology Database was queried for the number of individuals with ICD-9 diagnosis codes 845.

Interobserver Analysis of Standard Foot and Ankle Radiographic Angles.

Standard foot and ankle radiographs have long been studied and averages formulated in an attempt to provide a common framework for understanding the relationships of the foot and ankle, not only for surgical planning but also to determine normal versus abnormal relationships. The authors describe 8 angles measured on 100 patients by up to 18 observers (4 attending physicians, 12 residents, and 2 students). This study validates the previously documented normal angles using a significantly larger observer group as well as a greater number of analyzed angles.
