Patients undergoing a revision procedure, single-level procedure at L5-S1, or surgery indicated for infectious, malignant, or traumatic etiologies were excluded.

PROMs included VAS for back and leg pain, Oswestry Disability Index (ODI), and Short Form-12 (SF-12) Item Survey Mental (MCS) and Physical (PCS) Composite Scores with all values collected at the preoperative, 6-week, 12-week, 6-month, 1-year, and 2-year follow-up time point. Patients were grouped into 2 cohorts, depending on whether a patient underwent a MIS-TLIF or LLIF. Demographic and perioperative characteristics were compared between groups using χ 2 and Student t test for categorical and continuous variables, respectively. Mean PROM scores were compared between cohorts at each time point utilizing an unpaired Student t test.

However, incorporating functional parameters that consider the vertebrae orientation is important to minimizing surgical calculation errors.</p><p><strong>Methods: </strong>The authors developed parametric analysis software that integrates traditional and functional methodologies. The proposed method included functional thoracic kyphosis and functional lumbar lordosis calculated from the lines normal to the inflection points of the spine model. Using a synthetic lateral X-ray, the observer variability was computer-simulated generating 20 landmark sets that replicate the annotations of 20 observers. The analysis also included 10 clinical X-rays, annotated twice by 3 judges with a minimum 1-week interval. The spinal curvature angles were derived using the anatomic and functional methods. Statistical analysis were performed for comparison.</p><p><strong>Results: </strong>For the synthetic X-ray, the proposed method presented significantly less variability: TK (<±2.5 degrees, P =0.00023) and LL (<±5 degrees, P =0.00012). For the clinical X-rays, the interobserver reliability analysis yielded higher intraclass correlation coefficients (ICC) for functional TK (ICC>0.97) and functional LL (ICC>0.87) than for TK (ICC<0.91) and LL (ICC<0.89). Statistically significant differences were observed for both TK ( P =0.001) and LL ( P =0.030). Under the traditional method, observer variability led to measurement differences surpassing ±19 degrees, whereas differences with the proposed method were within ±10 degrees for both parameters.</p><p><strong>Conclusion: </strong>The vertebral endplate is not the most suitable place to measure spinal sagittal curvatures. Small changes in landmark position significantly alter the measured Cobb angle. The proposed method offers a substantial advantage regarding the influence of observer variability, in addition to the more individualized analysis.</p>","PeriodicalId":10457,"journal":{"name":"Clinical Spine Surgery","volume":" ","pages":"E494-E502"},"PeriodicalIF":1.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141261344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
