Aim:To correct persistent metatarsus adductus deformityusing percutaneous technique.Background:Metatarsus adductus (MA) foot deformity is characterized by a medial deviation of the forefoot at the level of the Lisfranc joint.Idiopathic MA deformity is the most common pediatric foot deformity with an incidence of 3%. A 4% to 14% of all MA deformities would further progress to a severe and rigid deformity, warranting surgical correction, starting at 4 years of age.Methods: Wedesigned a prospective study on thirty feet in eighteen patients with persistent metatarsus adductus. All cases underwent percutaneous capsulotomy of 1st cuneometatarsal joint, and percutaneous osteotomies of second, third, and forth metatarsals using a burr, and maintenance of correction using a single percutaneous k-wire fixation. For clinical evaluation, we used the bisector method, flexibility test, the first cuneometatarsal angle and metatarsal-metaphyseal angle measured in weight-bearing radiographs.Results:At the final follow-up all feet presented a normal heel bisector line. Radiologic parameters were normalized when compared with control feet. The mean surgical and hospitalization time was 22 minutes and 7.5 hours, respectively
