Abstract

We evaluated children with lower limb length discrepancy and angular deformity operated by the Metaizeau technique in the 2010-2014 period through a retrospective study of 11 patients analyzed in 2 groups. Group 1 (Lower limb length discrepancy), consisted of 5 patients, among whom 3 were operated only by Metaizeau technique, whereas the other 2 additionally required procedures for femoral elongation. We evaluated initial discrepancy, predicted discrepancy for ultimate control and at maturity, and final discrepancy. Group 2 (Angular deformity), consisted of 6 patients, among whom 1 had genu varum, 4 genu valgum and, 1 ankle valgus.  We evaluated anatomic femorotibial angle, anatomic lateral distal femoral angle, medial proximal tibial angle, and tibio talar angle. In both groups the complications were assessed. The average follow-up was 2 years and 5 months. In Group 1 we obtained the following values: average initial discrepancy, 7.64 cm; average discrepancy predicted for ultimate control, 8.54 cm; average final discrepancy, 7.62 cm and average correction achieved, 0.91 cm. In Group 2 the values were: average correction anatomic femorotibial angle, 16.85˚; average correction anatomic lateral distal femoral angle, 16.85˚ and average correction medial proximal tibial angle, 7.62˚. We found no complications in any patient. In 8  patients (72.72%) the technique was effective, while in 3 (27.27%) the results were poor due to technical errors or prediction errors . Metaizeau Technique, respecting the surgical details and making an accurate prediction is an effective, simple and uncomplicated procedure.
