The controllable antedisplacement of the vertebrae\u2010OPLL complex (VOC) through screws is both the most critical and technically challenging procedure, especially in osteoporosis (OP) condition. This study aims to introduce a modified method to significantly improve the procedure of VOC antedisplacement in ACAF.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The modified ACAF was used to treat 22 patients both with C\u2010OPLL and OP from January 2020 to January 2023. The cohort comprised 17 females and 5 males, with an age of 60.68\u2009\u00b1\u20091.2\u2009years (50\u201371\u2009years). During this modified ACAF, bone cement was injected into the VOC, and the corresponding steps of grooving were improved. Japanese Orthopedic Association (JOA) score, complications, and fusion conditions were documented. A paired <jats:italic>t<\/jats:italic>\u2010test was used to compare the changes before and after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010two C\u2010OPLL patients were successfully treated by the modified ACAF. The operation time was 270.5\u2009\u00b1\u200914.8\u2009min, and the intraoperative blood loss volume was 303.6\u2009\u00b1\u200913.0\u2009mL. All patients were followed up for 26.55\u2009months on average. The JOA score with 12.18\u2009\u00b1\u20091.68 at the last follow\u2010up was significantly improved (vs. 8.59\u2009\u00b1\u20091.89 of presurgery, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). No cement leakage was found during the augmentation, and 0.4\u2009mL of bone cement was injected in each VOC, which obviously enhanced screws anchorage. All VOCs were successfully hoisted after the augmentation without screw loosening. Twenty\u2010two C\u2010OPLL patients achieved satisfactory fusion at the last visit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Bone cement augmentation with modified
