A 40 year old male who slipped on a step and developed sudden pain on the lateral aspect of the ankle.

A normal X-Ray.

The ultrasound shows that all the ligaments surrounding the ankle joint are intact.

A complete tear is noted of the retinuculum over the peroneus tendons.

Note the dislocation of peroneus longus over the lateral malleolus on dynamic viewing with dorsi-flexion.

Fluid is seen surrounding both the tendons.
