Color Doppler Sonography Accompanied by Dynamic Scanning for the Diagnosis of Ankle and Foot Fractures.

Sonography is conventionally used to diagnose fractures by identifying cortical discontinuity of the bone. In this study, fracture sonography in addition to color Doppler and dynamic scanning was performed in settings with limited or no access to radiography. We describe 5 cases of ankle and foot fractures with the use of sonography to identify changes in the fractured site. The width of the fracture space increased on dynamic scanning, and the Doppler signals were generated inside the fracture space on dynamic scanning. In conclusion, color Doppler sonography accompanied by dynamic scanning is a useful adjunctive diagnostic tool in addition to previously described sonographic fracture findings.
