57. Are C7 Plumbline and Gravity Line Good Predictors of Quality of Life in Adults with Spinal Deformity?

BACKGROUND CONTEXT: Although most surgeons believe that adequate balance is important in the treatment of spinal deformity, there is no strong evidence supporting that concept. Only one group has found weak correlations between sagittal spinal balance and quality of life in patients with adult spinal deformity, but this finding has never been confirmed in another study. In addition, while the use of the gravity line is gaining interest in the evaluation of global balance, it remains unknown if this parameter is associated with quality of life.
