Musculoskeletal ultrasound of the ankle and foot.

Despite the tendency for injuries of the foot and ankle to be readily localized at physical examination, the examiner is advised to perform an ultrasound examination when indicated with a routine and systematic approach. This allows for comprehensive evaluation of all the relevant structures and affords the necessary experience to recognize abnormal anatomy when it is present. Musculoskeletal ultrasound examination strongly complements other diagnostic tools used in the diagnosis and treatment of foot and ankle pathology.
