Clinical bottom line

Ottawa-positive ankle injuries get targeted radiographs — ankle series for malleolar findings, foot series for midfoot findings.

Summary

Bony tenderness at the malleoli or midfoot landmarks, or inability to bear weight, satisfies the Ottawa ankle rules and indicates radiography of the ankle and/or foot series as directed by the positive element.
