Ankle Sprains
Key Points
Before diagnosing an ankle sprain, consider an avulsion fracture of the base of the 5th metatarsal, an Achilles tendon injury, or a talar dome fracture. Use the Ottawa ankle and foot rules to help decide whether x-rays are necessary. Evaluate joint stability by stress testing (eg, anterior drawer test), but if needed, delay this testing until swelling and pain subside. Encourage early mobilization if the sprain is mild.
