ðĶī BT = Bone tenderness.
ðĪ Treat sprains with RICE (Rest, Ice, Compression, Elevation, + Analgesia).

âđïļ Additional Notes
- â
Ottawa Ankle Rules are highly sensitive (~100%) for ankle & midfoot fractures â helps rule out fracture safely.
- â Do not apply in:
- Multiple injuries, head injury, or intoxication.
- Peripheral neuropathy / reduced sensation.
- Strong suspicion of stress fracture (often subtle & not tender acutely).
- ð If swelling & pain persist after 5â7 days â repeat assessment (occult fractures may later become visible).
ð ïļ Management of Ankle/Foot Sprains (RICE Protocol)
- ð Rest: Limit weight-bearing, crutches if required. Resume activity gradually as pain allows.
- ð§ Ice: Apply 15â20 min every 1â2 hrs for first 48 hrs to reduce pain/swelling.
- ðĐđ Compression: Elastic bandage/ankle support. Must be snug but not restrictive to circulation.
- ðĶĩ Elevation: Keep above heart level especially first 24â48 hrs to reduce swelling.
- ð Analgesia: NSAIDs or paracetamol; NSAIDs also reduce inflammation.
ðĪ When to Refer
- ð§ Suspected high ankle sprain / syndesmotic injury (positive squeeze test).
- âģ No improvement after conservative management, or persistent instability.
- â ïļ Neurovascular compromise OR severe functional limits beyond 2â6 weeks recovery window.
