Ultrasound of the ankle.

Because of their size and superficial location the ankle tendons can be well evaluated with ultrasound (US). The excellent definition of the modern high frequency probes allows us to consider US the technique of first choice in their assessment. Basic US appearances correlate well with the MRI findings. Since US can diagnose most tendon disorders including tendinopathies, tears, dislocations and enthesopathies MRI is less often utilized. US can easily depict the main ankle ligaments. The basic US appearance of ligament tears is well known. US can be considered an inexpensive and accurate technique in the evaluation of ankle sprains.
