Magnetic resonance imaging in follow-up of treated clubfoot during childhood.

In this study, we evaluated the short-term results of surgically treated clubfoot with magnetic resonance imaging (MRI). T1- and T2-weighted MRI images with 4-mm slices in the standard anatomic sagittal, transverse, and coronal planes were obtained in seven cases of clubfoot aged 4--11 years (mean 5.6 years old). The mean follow-up period was 3.6 years (ranged between 2 and 6 years). Sagittal talocalcaneal angle, talar head and neck axis internal rotation, calcaneal axis internal rotation, transverse talar neck and head/calcaneus angle and posterior calcaneus external rotation were measured. Three cases with dorsal talonavicular subluxation and a case of calcaneocuboid luxation were demonstrated by MRI. It was concluded that MRI may help to understand results of surgically-treated clubfoot by revealing hindfoot articular relationships and many complications.
