摘　　要：Dynamic supination of the foot is a common residual deformity in children with clubfeet treated with the Ponseti method. Transfer of the anterior tibialis tendon (ATT) to the lateral cuneiform is an effective method for correcting this deformity when the cuneiform is ossified in children who are 3 to 5 years of age. We describe two cases of a previously unreported method of ATT transposition for correction of bilateral residual dynamic supination in a 26-month-old and a 19-month-old patient. Both patients presented shortly after birth with bilateral congenital idiopathic clubfoot and were initially treated with the Ponseti method. Both had residual deformity following initial treatment that included posterior contracture and metatarsus adductus with dynamic forefoot supination. This was surgically corrected with a posterior release and medial release of the 1st metatarsal/1st cuneiform joint. To correct dynamic supination, the ATT was transplanted laterally into the released midfoot joint. These two patients were followed post-operatively for 7.5 years and have correction of their residual deformity in both feet based on subjective functioning, appearance, range of motion, strength, and gait. Both have excellent lateral pull of their ATT, which functions as a strong foot dorsiflexor. No residual supination is present. This is the first report of lateral transposition of the ATT as an interposition graft at the released 1st metatarsal/1st cuneiform joint in patients with relapsed clubfoot. We suggest that this method should provide a high level of functioning in children with relapsed supination deformity and whose 3rd cuneiform has not yet ossified.Dynamic supination of the foot is a common residual deformity in children with clubfeet treated with the Ponseti method.
