When patients were stratified into mild, moderate, and severe groups, age in the mild group, nonanatomic reduction in the moderate group, and race in the severe group were found to be independently associated with increased %LCO using multivariable analysis.</p><p><strong>Conclusions: </strong>The amount of LCO was found to be related to nonanatomic reduction, younger age, and Black and Asian race. Interestingly, it was not related to the amount of initial displacement or type of hardware used. To date, this is the largest study investigating LCO in surgically treated lateral condyle fractures.</p><p><strong>Level of evidence: </strong>Level III-retrospective cohort study.</p>","PeriodicalId":16945,"journal":{"name":"Journal of Pediatric Orthopaedics","volume":" ","pages":"e10-e17"},"PeriodicalIF":1.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142055918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
