The purpose of this retrospective study was to determine whether high-resolution sonography can aid in the diagnosis of radiographically occult fractures in the foot and ankle. ⋯ Sonography-a readily available, noninvasive imaging technique-can provide important information about soft tissue injuries and cortical discontinuities in the foot and ankle area. Using this procedure, occult fractures can be identified and delineated, and costly procedures such as MRI can be avoided.
