In addition, surgeons need to consider that the hip–spine motion may change from the preoperative one owing to changes in some spinopelvic parameters following THA. However, the significance of these changes is not consistent across the studies. Since low PI, PI-LL mismatch, and low SS during sitting and standing may contribute to the risk of prosthetic impingement followed by dislocation, great care should be taken regarding the loss of spinopelvic mobility after spinal fusion surgery.</p></div>","PeriodicalId":100795,"journal":{"name":"Journal of Joint Surgery and Research","volume":"2 ","pages":"Pages 62-69"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949705123000026/pdfft?md5=24d4f1f6f547896136415fdc649210c2&pid=1-s2.0-S2949705123000026-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50194915","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}
