　成人脊柱変形術後患者73例を対象にして，年齢が矢状面パラメータへ及ぼす影響を調査した．術後成績が良好な症例を若年群(65歳未満)と高齢群(65歳以上)に分け比較すると，PI-LL(pelvic incidence-lumbar lordosis)(若年群：10°，高齢群：11°)とPT(pelvic tilt)(若年群：25°，高齢群：28°)の値に有意な差がなく，TK(thoracic kyphosis)(若年群：28°，高齢群：38°)は高齢群が有意に大きかった．成人脊柱変形の手術治療は主に矯正固定術であり，手術で固定した角度で長い期間を過ごすことになる．よって，手術における矯正目標値は，年齢層を超越し経年的な変化を加味した値が理想的と考える．
