In subgroup analyses, cement augmentation, while possibly inferior to bone grafts in pain relief and function, showed comparable effects on radiographic outcomes. No significant difference between strut fibular and non-fibular grafts was observed.</p><p><strong>Conclusions: </strong>Augmentation with bone grafts or cement does not convincingly reduce complication risks or screw protrusion compared with locking plate fixation alone. However, it improves pain, function, and radiographic outcomes in osteosynthesis of proximal humerus fractures.</p><p><strong>Level of evidence: </strong>II.</p><p><strong>Registration: </strong>CRD42024500403.</p>","PeriodicalId":48603,"journal":{"name":"Journal of Orthopaedics and Traumatology","volume":"26 1","pages":"47"},"PeriodicalIF":3.0,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12271005/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144660843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
