Previous studies have shown that clinical criteria can be used for determining the need for radiographs after spraining injuries of an ankle. Following the criteria of the "Ottawa Ankle Rules" (OAR) fractures could be ruled out with a sensitivity of 100% and a specificity of 50% while reducing radiographs by 28%. The aim of this study was to assess the "OAR" when applied in a German emergency department. ⋯ Sensitivity using the "OAR" was 94% and specificity 17%. We found that 15% less radiographs can be ordered applying the "OAR". The "OAR" have the ability to rule out significant fractures at the ankle and midfoot.
