Previous studies showed that the stress on the UIV is most reduced when ORPS is >80%. However, it remains unclear whether these results are clinically valid.\nMethods: A total of 297 patients who had undergone adult spinal deformity surgery were included in the study. UIVF incidence was assessed and a logistic regression analysis was conducted to uncover the risk factors for UIVF. The group with an ORPS ≥80% and <80% was defined as the H (n=198) and L (n=99) group, respectively.\nResults: The mean age of both groups was 69 years. The average ORPS in the L and H groups was 70% and 85%, respectively. The incidence of UIVF was 30% in group L and 15% in group H (P<0.01). Additionally, the 99 patients in group H were subdivided into two groups, according to whether the screws penetrated the anterior wall of the vertebral body: 68 patients had no penetration (group U), while it was present in 31 patients (group B). A total of 10% and 26% of the patients in the U and B groups, respectively, experienced 1 UIVF (P<0.05). Logistic regression analysis of possible UIVF risk factors revealed an odds ratio of 3.9 for ORPS <80% (P=0.007, 95% confidence interval 1.4-10.5).\nConclusion: To reduce UIVF, screw length should be set with a target ORPS of 80% or higher. If the screw is long enough to penetrate the anterior wall of the vertebral body, the risk of UIVF is greater.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wolters Kluwer Health","subitem_publisher_language":"en"}]},"item_3_relation_26":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"37026769","subitem_relation_type_select":"PMID"}}]},"item_3_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1097/BRS.0000000000004661","subitem_relation_type_select":"DOI"}}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2023 Wolters Kluwer Health, Inc.
