Comparison of the radiographic outcomes using hybrid constructs, pedicle screws or hook instrumentation for the treatment of idiopathic scoliosisOBJECTIVES: to compare the radiographic outcomes of patients with adolescent idiopathic scoliosis (AIS) treated surgically with three different instrumentations (hooks only, hybrid or pedicular screws), with minimal of one-year follow-up. METHODS: retrospective radiographic evaluation of patients with idiopathic scoliosis treated with different instrumentations, in the preoperative, postoperative and one year postoperative follow-up using the Cobb method. RESULTS: no differences were found in the behavior of the curves during the first year of follow-up concerning the thoracic and lumbar curves or the kyphosis. In a quantitative analysis, no statistical difference was found in the thoracic curves (p=0.052) or lumbar curves (p=0.332) in the preoperative period among the three groups. The three instruments showed similar behaviour patterns, with no quantitative differences in the correction of thoracic curves (p=0.052) and lumbar curves (p=0.267) during the immediate postoperative period and after one year of follow-up. CONCLUSIONS: the three instrumentations yield similar radiographic findings in patients with AIS.
