Restoring sagittal and frontal balance following posterior instrumented fusion

Abstract

Correction techniques for adolescent idiopathic scoliosis have evolved over the years as the understanding of the disease and the implant technology advanced. Utilization of the modern implant systems, along with the appropriate corrective maneuvers and selection of the appropriate levels of instrumentation, improves the outcomes after surgical treatment of adolescent idiopathic scoliosis. Coronal and sagittal balance are important predictors for successful posterior spine fusion. Many corrective methods have been developed to address the multiple facets of the spinal deformity and curve types. Treating surgeons should familiarize themselves with all of the techniques, their utility, and appropriate usage in different deformity settings. A literature review is provided with the best evidence available to achieve optimal deformity correction to help guide treating physicians.
