Corrección del Hallux valgus en metatarso adductus

Abstract

Background To describe the frequent association of Metatarsus adductus and Hallux valgus in the adult foot as a cause of insufficient correction after application of common surgical techniques. Method and material A retrospective review was made of 16 cases in 15 patients with clinical and radiologic metatarsus adductus operated by Hallux valgus from 2006 to 2008. In all cases, a correction of the deformity lower than 10° was observed. Results The mean postoperative correction was 9°. The mean inclination of first cuneometatarsal joint was 65°. We did not find any relationship between Metatarsus adductus magnitude and postoperative Hallux valgus correction. The best results were observed with Scarf Osteotomy. Discussion There is controversy on the Metatarsus adductus and Hallux valgus relationship. Although poor application of the surgical techniques is the most important cause of correction failure, the limited literature references and the comparison with similar results, may show this association as a cause of the difficulty in the application of conventional surgical techniques. Poor performance of these techniques is an important cause of correction failure and must be evaluated. Conclusion Metatarsus adductus in the adult foot with Hallux valgus to be operated must be detected and seen as a deformity that is difficult to correct. Preoperative planning and choice of surgical technique must assess these angular deformities to avoid a poor result for the patient.
