Distal femoral hemiepiphysiodesis using screw and non-absorbable filament for the treatment of idiopathic genu valgum. Preliminary results of 12 knees

Abstract Introduction Different techniques for gradual correction of angular deformities of lower limbs exist. Screws and nonabsorbable filament has been described as an effective alternative for transitory hemiepiphysiodesis in New Zealand rabbits. Hypothesis Hemiepiphysiodesis using screws and non-absorbable filament is effective in pediatric population, for correction of genu valgum. Methods Retrospective evaluation, 12 knees in 6 patients younger than 15 years (3 female), operated because of genu valgum. An anchoring system with two 4.0 mm cancellous screw with metal washer joined by FiberWire #2.0 filament. Initial and final intermalleolar distance (IMD) and mechanical lateral distal femoral angle were compared, recording complications. Mann–Whitney test was used for statistics, with significance value
