Surgical Treatment of Lower Limb Length Discrepancy and Angular Deformity by Epiphysiodesis with Transphyseal Screws (Metaizeau Technique)
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.
