Ultrasound findings of the painful ankle and foot.

OBJECTIVES

To document the prevalence and spectrum of musculoskeletal ultrasound (MSKUS) findings at different parts of the foot.

MATERIALS AND

METHODS

All MSKUS studies conducted on the foot during a 2-year period (2012-2013) at the Department of Radiology were reviewed. Demographic parameters including age, gender, and MSKUS findings were documented.

RESULTS

Three hundred and sixty-four studies had been conducted in the 2-year period. Ninety-three MSKUS evaluations were done for the ankle, 30 studies for the heel, and 241 for the rest of the foot. The most common MSKUS finding at the ankle was tenosynovitis, mostly in female patients; at the heel it was Achilles tendonitis, also mostly in female patients; and for the rest of the foot it was fluid collection and presence of foreign body, mainly in male patients. The number of different MSKUS abnormalities that were reported was 9 at the ankle, 9 at the heel, and 21 on the rest of the foot.

CONCLUSIONS

MSKUS has the potential for revealing a huge spectrum of abnormalities. The most common finding was collection/hematoma and foreign bodies at the foot, tenosynovitis at the ankle, and Achilles tendinitis at the heel.
