Congenital vertical talus (CVT) is a rare deformity of the foot. It has been historically treated with extensive soft tissue releases with significant associated complications. Recently, reverse Ponseti-type casting followed by minimally invasive or percutaneous reduction and fixation has been described with excellent results in separate cohorts of either idiopathic or teratologic cases of CVT. There are currently no studies that compare the outcomes between the two types. We present a prospective cohort of 13 patients (21 feet) in which this technique has been used in both idiopathic and teratologic associated cases of CVT. Clinical, radiographic and parent-reported outcomes were obtained at a mean follow up of 36 months (range 8–57). Clinical and radiographic scoring was according to the system of Adelaar and parent-reported outcomes were assessed using the POSNA paediatric outcomes data collection instrument (PODCI).Background
