Peroneal tendon tear
Peroneal tendon tear presentation
Persistent pain posterior to the lateral malleolus +/- swelling

Typical cause of medial ankle injury? Ligament injured?
Forced eversion; deltoid ligament
Syndesmotic sprain presentation?
Pain and disability are often out of proportion to the injury; positive ankle squeeze test
Grade I ankle sprain
Stretching and/or a small tear of a ligament
Mild tenderness/swelling
Slight to no functional loss
No mechanical instability
No excessive stretching or opening of the joint with stress
Grade II ankle sprain
Incomplete tear
Tenderness over involved structures, mild to moderate pain, swelling, ecchymosis
Moderate functional impairment;
Mild to moderate instability
Stretching of the joint with stress but with a definite stopping point
Grade III ankle sprain
Complete tear and loss of integrity of the ligament Severe swelling (>4cm about the fibula) and ecchymosis Inability to bear weight, mechanical instability Significant stretching of the joint with stress without a definite stopping point
According to the Ottawa Ankle Rules, when are radiographs of the ankle indicated?
Pain in the malleolar zone AND either: bony tenderness along the distal 6cm posterior of the edge of either malleolus OR inability to bear weight 4 steps BOTH immediately after injury and in the ED

Pain in the midfoot region AND either: bondy tenderness at the navicular bone or base of the 5th metatarsal OR inability to bear weight 4 steps BOTH immediately after injury and in the ED
Management of ankle sprains
RICE: rest for the first 72 hours/stretching after the first few days; ice several times/day for 10 minutes; compression ; elevation
+
Pain control - anti-inflammatory
What is the most effective compression for ankle sprains?
Semi-rigid ankle support
