Early surgical treatment for congenital vertical talus

Congenital vertical talus is characterised by a dislocated talonavicular joint in association with an equinus position of the calcaneus. We report the results in 13 operated feet in 10 children, 3 of whom (5 feet) presented with a primary neurological disorder and 2 of whom (3 feet) suffered from arthrogryposis multiplex congenita. The other children were normal. All patients were surgically treated by a one-stage procedure which included reduction of the talonavicular joint and correction of the hindfoot equinus, trying to avoid tendon lengthenings and transfers. The age at operation was between the 3rd and the 6th month of life, with one child being operated on later due to other reasons. The patients were reviewed after an average time of 3.5 ± 2.2 years. The clinical results were good or excellent in ten feet. Two feet showed partial or complete recurrence and one foot was slightly over-corrected. Radiographic angle measurements (talo-metatarsal I angle and talocalcaneal angle on the anteroposterior radiograph; talocalcaneal, tibiotalar and tibiocalcaneal angles on the lateral radiograph) returned to normal values in the ten good or excellent feet. Early operative treatment for congenital pes vertical talus leads to very satisfactory functional and cosmetic results, usually avoiding extensive procedures including tendon lengthenings and tendon transfers.
