目的：成人脊柱変形(ASD)患者におけるSagittal age-adjusted score(SAAS)と近位隣接椎間後弯障害(PJF)について解析した．対象と方法：ASDの診断にて二期的前後方矯正固定手術を行った60症例を対象とした．Pelvic incidence(PI)-lumbar lordosis(LL)とSAASから，under-corrected群，matched群，over-corrected群に分類し，PJFの有無を比較した．結果：SAASでは52例(86.7％)がover-corrected群であった．Matched群とover-corrected群でPJFの有無は有意差がなかった．結語：SAASでは多くの症例で過矯正であったが，PJFの有無には統計学的有意差はなく，アライメント以外の評価が必要である．
