　背景：仙椎から仙腸関節を貫通させ遠位部を腸骨とする新しいスクリュー固定方法(sacral-alar-iliac fixation：以下，SAIF)が成人脊柱変形例に対する後方矯正固定手術において有用であるかを検討した．

　対象と方法：Cobb角40°以上の胸腰椎・腰椎変性後側弯症6例を対象とした．術前後の臨床成績，骨癒合，矯正率を検討した．

　結果：JOAスコアは術前11.3点，最終診察時21点(改善率54.9%)であった．全例，腰仙椎間の骨癒合が得られ，皮膚トラブルはなかった．Cobb角の矯正率は68.1％で良好であった．

　まとめ：SAIFは重度脊柱変形に対する矯正固定術における有用な遠位部アンカーである．
