Which is the role of dynamic high-resolution ultrasound (D-HRUS) in the assessment of plantar plate tears?

Purpose: Plantar plate tears are often unidentified causes of hindfoot discomfort. The purpose of our work is to describe the normal and pathologic appearance of plantar plate, assessed with dynamic high resolution ultrasound (D-HRUS). Methods and Materials: We used D-HRUS to assess 22 patients (age range 38–71) with an orthopaedic diagnosis of plantar plate tear. A Magnetic Resonance (MR) control was performed in all cases. Moreover, we performed D-HRUS on 10 healthy volunteers to understand the correct scan technique of the plantar plate and to determine the correct dynamic manoeuvres that allow to depict the…
