PURPOSE: Previous studies have demonstrated vertebral coplanar alignment (VCA) as an effective surgical option for @entity1615 ( @entity1615 ). The purpose of this study is to analyze the outcome of VCA for the surgical correction of adult @entity2112 (AdIS). METHODS: 35 AdIS @entity1 (mean age: 24.2  years) undergoing VCA-instrumentation were reviewed. The main thoracic curve and @entity1513 ( @entity1513 , T5-T12) were evaluated preoperatively, immediate postoperatively, and at the final follow-up (>1  year). All @entity1 were stratified by the @entity1513 modifier before surgery: "+" ( @entity1513 , >40  ), "-" ( @entity1513 , <10  ), and "N" ( @entity1513 , 10  -40  ) for normal. The apical vertebral body-to-rib ratio (AVB-R), rib hump (RH), and rotational angle to sacrum (RAsac) were measured to assess the correction of @entity717 . Quality of life was evaluated with @entity6815 -20 questionnaires. RESULTS: The main thoracic curve (59.1   vs. 19.3  , P  <  0.001) and @entity717 (AVB-R: 2.4 vs. 1.7  %, P  <  0.001, RH: 34.9 vs. 19.1  mm, P  <  0.001, RAsac: 19.6   vs. 11.9  , P  <  0.001) were significantly reduced with surgery. @entity85 improved significantly in group "+" (51.4   vs. 31.6  , P  <  0.001) and group "-" (6.2   vs. 20.1  , P  <  0.001), while no significant postoperative change in @entity1513 was observed in group "N" (23.5   vs. 26.3  , P  =  0.270). @entity1 were followed for an average of 18.7  months with no significant loss of correction. @entity6815 scores improved greatly from 57.7 preoperatively to 71.6 at the final follow-up. CONCLUSIONS: VCA can be effectively used for the correction of the @entity717 , with better sagittal profile restoration in adult thoracic @entity2112 with @entity893 .
