Introduction: Growth modulation allows correction of deformities in skeletally immature patients. A new implant (eightplate) that presents some advantages compared to its predecessors has been proposed. The aim of this study is to evaluate the radiographic results and complication rate in a consecutive series of patients treated with this method. Methods: The medical records of skeletally immature patients operated on to correct angular deformities of the lower extremities with eigth-plate guided growth between January 2009 and July 2013 were retrospectively reviewed. Demographics, radiographic angular deformity correction and complication rate were evaluated. Results: Twenty seven patients (12 boys and 15 girls; 47 physes) were evaluated. Thirty eight valgus deformities and nine varus deformities were treated. Of 47 physis, 33 were in the distal femur, 12 in the proximal tibia and 2 in the distal tibia. Age at the time of surgery averaged 11.8 ± 1.36 years (range 8-14). The average time between placement and removal of the implant was 10.6 ± 3 months (range 7-26). All patients except one achieved complete correction of the deformity. There were 6 postoperative complications, and two required reintervention (a rebound and one implant migration). Conclusion: The use of plates in 8 for correction of angular deformities in skeletally immature patients is an effective method with a low complication rate.
