Ottawa rules meta-analysisBMJ (Clinical research ed.) 2003
Accuracy of Ottawa ankle rules to exclude fractures of the ankle and mid-foot: systematic review
Sensitivity was almost 100% with low negative likelihood ratios for ankle and midfoot in adults and children, so a negative rule makes fracture very unlikely; specificity was only modest.

Decision rules for the use of radiography in acute ankle injuries. Refinement and prospective validation
The refined rules detected essentially all clinically significant malleolar and midfoot fractures in validation, while allowing a substantial reduction in radiography.
