Résumé
Two basic methods for genu valgum correction are osteotomy and internal fixation or external fixator assited correction. External fixators have the advantage of stabilizing fragments before osteotomy allowing better control of fragments and preventing secondary displacements. The purpose of this study was to evaluate the efficacy and complications of fixator assisted correction for genu valgum and internal fixation, using the AO distal femur pediatric osteotomy plate. Thirty-six limbs in 26 patients (age 10-16 years) underwent osteotomy in the distal femur at CORA. Open lateral wedge osteotomy was done; the desired position obtained was temporarily stabilized by connecting the pins with the AO external fixator and stabilized with 90 degrees AO distal femur pediatric locking plate and gap grafted with hydroxyapatite bone granules. Translation of distal fragment was required in 17 osteotomies (53.12%). Osteotomies united within 12 weeks; no non-union was observed. The range of motion was full in all patients. The mean tibiofemoral angle was corrected by 12 degrees and the mean mechanical LDFA was corrected to 87 degrees. There was no secondary deformity, either in the rotational or sagittal plane. This method combines the modularity of external fixator and the advantages of internal fixation.

Background and Purpose
UNASSIGNED
Two basic methods for genu valgum correction are osteotomy and internal fixation or external fixator assited correction. External fixators have the advantage of stabilizing fragments before osteotomy allowing better control of fragments and preventing secondary displacements. The purpose of this study was to evaluate the efficacy and complications of fixator assisted correction for genu valgum and internal fixation, using the AO distal femur pediatric osteotomy plate.
Materials and Methods
UNASSIGNED
Thirty-six limbs in 26 patients (age 10-16 years) underwent osteotomy in the distal femur at CORA. Open lateral wedge osteotomy was done; the desired position obtained was temporarily stabilized by connecting the pins with the AO external fixator and stabilized with 90 degrees AO distal femur pediatric locking plate and gap grafted with hydroxyapatite bone granules.
Results
UNASSIGNED
Translation of distal fragment was required in 17 osteotomies (53.12%). Osteotomies united within 12 weeks; no non-union was observed. The range of motion was full in all patients. The mean tibiofemoral angle was corrected by 12 degrees and the mean mechanical LDFA was corrected to 87 degrees. There was no secondary deformity, either in the rotational or sagittal plane.
Conclusion
UNASSIGNED
This method combines the modularity of external fixator and the advantages of internal fixation.
