ANKLE SPRAIN-INX & MANAGEMENT

1. Pain over the anterior talo-fibular ligament, hematoma discoloration & positive anterior drawer test has a 96% sensitivity & 84% specificity for diagnosing a grade 2/3 sprain.

2. A positive squeeze test (compressing the tibia and fibula at mid-calf) and external rotation test (externally rotating the dorsi-flexed foot) are suggestive of a syndesmotic injury.

3. Investigated with radiography.

4. Differential: avulsion fractures of the base of the fifth metatarsal can occur from the pull of peroneus brevis.

5. If non-displaced or mildly displaced, these fractures can usually be treated non-operatively with use of an orthopedic shoe for 1 to 2 weeks.
