Radiology of Pes Equinovarus
Eventhough several angle measurements were described on the radiographs of clubfoot, evaluation of th deformity and follow-up of treatment are preferred to be done clinically. I personally use clinical evaluation in most cases. However, when I perform the Ponseti treatment, if I need to be sure about performing percutaneous heel cord lengthening, I would like to see the lateral foot x-rays to see whether calcaneus is still in plantar flexion or not. Also, I use the radiographs as an asset to make treatment decision on recurrent and/or neglected pes equinovarus cases.
Radiology of Clubfoot
On the Antero-posterior (AP) rdiographs of foot, the angle between talus and calcaneus is 20-40 degrees and the angle on lateral foot x-rays is 20-50 degrees. Whereas, the clubfoot x-rays of patients show talus being parallel to calcaneus on both anteroposterior and lateral x-rays.
We call on foot radiographs, if we plan to operete or follow the surgery results.
Radiological review can also utilize ultrasonography and MR Imaging. There are several studies of MR and Ultrasonography use in Clubfoot. MRI and Ultrasonography may have a role in complex deformities and academic studies.
