The differences of the above indexes between the two groups were compared, and the differences of the above indexes between the two groups were compared respectively in the male and the female. Random forest model was used to analyze the influencing factors of anterior shoulder instability.</p><p><strong>Results: </strong>The comparison between the two groups and the comparison between the two groups in the male and the female showed that the ratio of of the instability group glenoid height to width was larger than that of the control group, the glenoid width and humeral containing angle were smaller than those of the control group, and the differences were significant ( <i>P</i><0.05); there was no significant difference in glenoid height, glenoid inclination, and glenoid version between the two groups ( <i>P</i>>0.05). The accuracy of the random forest model was 0.84. The results showed that the top four influencing factors of anterior shoulder instability were ratio of glenoid height to width, the humeral containing angle, age, and glenoid width.</p><p><strong>Conclusion: </strong>Ratio of glenoid height to width and the humeral containing angle are important influencing factors of anterior shoulder instability.</p>","PeriodicalId":23979,"journal":{"name":"中国修复重建外科杂志","volume":"38 12","pages":"1433-1438"},"PeriodicalIF":0.0,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11655379/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142855726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
