Penetrating injuries to the sole of the hoof are common in horses. Prognosis and treatmentdepend on the structures involved. In this report, nine horses are described with a penetratinginjury to the sole of the hoof that then underwent magnetic resonance imaging (MRI) examination.The radiographic examination performed in seven of these horses provided information about thebone involvement and an MRI examination was performed in all cases to obtain information aboutthe affected soft tissues. MRI has excellent soft tissue contrast and can provide detailed images inany anatomical plane. For all nine horses, the MRI examination provided a clear guidance towardprognosis and a treatment plan. For two of the horses, the MRI examination confirmed that onlysuperficial debridement was required. In seven of the horses, the MRI findings indicated that amore invasive approach was needed, such as navicular bursoscopy or street-nail procedure.This study illustrates that an MRI examination can provide useful additional informationleading to an appropriate therapy and prognosis, and shows a good correspondence between MRIobservations and surgical findings.
