Analytical radiography of clubfoot after tenotomy.

UNLABELLED: The study was undertaken to determine the radiographic impact of the tenotomy after the Ponseti method. We report a retrospective and prospective radiographic analysis of 37 clubfeet after the Achilles tenotomy. The talocalcaneal angle was measured on lateral and anteroposterior views; the tibiotalar and the tibiocalcaneal angles were evaluated on the lateral view. The mean age at the time the last radiographic analysis was performed was 19 months (range, 13-35 months). Both studies have the same conclusion: the Achilles tenotomy decreases the lateral tibiocalcaneal angle and increases the lateral talocalcaneal angle. Furthermore, the tenotomy effect tends to diminish with time. LEVEL OF EVIDENCE: therapeutic study, level IV.
