Risk factors for PJFx and PJFx-M were analyzed, focusing on demographic and radiographic parameters. In PJFx-M cases, we specifically assessed sliding length, screw protrusion, and superior articular facet fractures.ResultsPJFx occurred in 102 patients (23.3%). Significant risk factors for PJFx included a lower Hounsfield unit (HU) value at the upper instrumented vertebra (UIV) and reduced preoperative lumbar lordosis. PJFx-M was identified in 10 patients (2.3%). Radiographic predictors of PJFx-M included increased sliding length, screw protrusion into the upper vertebra, and bilateral superior articular facet fractures (all <i>P</i> < 0.001). Additionally, a fall within 1 month of symptom onset was frequently observed in PJFx-M cases. PJFx-M was not associated with demographic factors or body mass index.ConclusionsLower HU at the UIV and reduced preoperative lumbar lordosis were key predictors of PJFx. PJFx-M should be suspected in the presence of increased sliding length, screw protrusion into the upper vertebra, superior articular facet fractures, and a recent fall. These findings highlight the importance of vigilant postoperative radiographic and clinical monitoring to enable early detection and intervention, potentially preventing neurological deterioration.</p>","PeriodicalId":12680,"journal":{"name":"Global Spine Journal","volume":" ","pages":"21925682251359948"},"PeriodicalIF":2.6,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12245815/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144600222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were stratified by procedure type. Data included demographics, perioperative outcomes, and the 5-item Modified Frailty Index (MFI-5). Fatty infiltration was graded at L4-5 using the Goutallier classification (intraclass correlation coefficient = 0.908). Opportunistic osteoporosis screening used computed tomography-based Hounsfield units (HU) at L1-2. The relationships between Goutallier grade, demographics, MFI-5 score, and postoperative outcomes were analyzed using Chi-squared analyses, Fisher's exact test, Analysis of Variance, and multivariable logistic and linear regression.ResultsIn total, 314 patients met the inclusion criteria. Mean age was 68.9 ± 8.6 years; mean Goutallier score was 2.2 ± 1.1 and MFI-5 was 1.3 ± 1.0. Goutallier score significantly correlated with age, American Society of Anesthesiologists grade, steroid use, MFI-5, discharge disposition, and 180 day complications and reoperation. Subgroup analyses revealed differing associations between Goutallier score and comorbidities/outcomes across procedure types. Multivariable regression confirmed Goutallier score as predictive of 180 day complications, reoperation, non-home discharge, and frailty.ConclusionGoutallier score is a predictive marker of frailty and postoperative outcomes in lumbar spine surgery.

There was no significant difference in fusion or reoperation rate based on subsidence occurrence. Both vertebral HU (<i>P</i> = .012) and EP-HU (<i>P</i> < .001) were associated with subsidence. In receiver operating curves, EP-HU was more optimal for subsidence prediction than vertebral HU, but the aggregate metric further optimized the specificity and total area under the curve. In a predictive logistic regression model EP-HU + vertebral HU (aggregate HU < 515 odds ratio: 7.82, <i>P</i> < .001) was a strong independent predictor of subsidence.ConclusionPreoperative calculation of EP-HUs in addition to vertebral HUs may enhance prediction of TLIF subsidence where aggregate endplate and vertebral HU < 515 can be used to identify high risk patients.</p>","PeriodicalId":12680,"journal":{"name":"Global Spine Journal","volume":" ","pages":"21925682251356986"},"PeriodicalIF":2.6,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227440/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
