Selection of Fusion Levels in Idiopathic Scoliosis


The selection of fusion levels in idiopathic scoliosis requires the consideration of many factors. As modern instrumentation systems for correcting spinal curvature have developed, control of the correction of spinal deformity in all planes has improved, and the “rules” regarding selection of fusion levels have evolved with a trend toward fusing fewer segments of the spine. However, the principles and variables to consider in selecting levels of the spine for fusion have remained consistent. This article is designed to review these principles and to offer basic guidelines in selecting fusion levels in scoliosis treated through posterior fusion and instrumentation.
