To tackle these clinical challenges, this study has developed a ready-to-use hemostatic moldable bioactive bone putty (BP) that excels in rapid hemostasis and promotes bone regeneration. BP is a formulation made from polyethylene glycol and pre-gelatinized hydroxypropyl distarch phosphate as a molding agent, along with calcium sulfate bone cement and calcium phosphate bone cement as bioactive components. While the application method remains the same as that of bone wax, BP encourages swift thrombus formation, significantly reducing coagulation time and blood loss. Additionally, BP improves its mechanical strength through hydration reactions upon exposure to bodily fluids, providing essential support for bone tissues while completely degrading within 8 weeks of implantation. In vitro cell studies have underscored the excellent biocompatibility of BP, demonstrating its capacity to stimulate the proliferation of BMSCs, increase the expression of key osteogenic genes, and increase calcium nodule deposition. Histological analyses have further revealed the positive impact of BP on osteogenesis, whereas in vivo experiments have shown significant inhibition of inflammatory fiber formation. Overall, the BP has emerged as an innovative solution for accelerating hemostasis and facilitating regenerative repair in cases of bone injury.","PeriodicalId":516419,"journal":{"name":"临床骨科杂志","volume":"2 1","pages":"132-141"},"PeriodicalIF":0.0,"publicationDate":"2025-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904765","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}

In clinical practice, chronic osteomyel itis often leads to bone tissue necrosis, with biofilm formation being a key factor in treatment failure. Although traditional antibiotic-loaded polymethacrylate (PMMA) bone cement is effective for initial bacterial inhibition, it faces challenges such as non-degradability, and the risk of promoting antibiotic resistance. Therefore, in this study, an epigallocatechin gallate (EGCG)-loaded biodegradable calcium sulfate (CSC) and silver-doped bioactive glass cement (AgBGC) composite bone cement was developed (E-AgCSBC). The combination of CSC and AgBGC enhanced the mechanical properties, effectively prolonged the setting time, and improved the anti-washout property of the CSC cement. The antibacterial properties of the composite cement were validated through plate coating and in vitro anti-biofilm tests. In addition, E-AgCSBC composite cement exhibited good cytocompatibility and promoted the migration and osteogenic differentiation of BMSCs in vitro , indicating its potential for the treatment of chronic osteomyelitis.","PeriodicalId":516419,"journal":{"name":"临床骨科杂志","volume":"2 1","pages":"142-153"},"PeriodicalIF":0.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913667","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}

In severe cases, surgical removal of the protruding disc is required in the late stages. Given the limited self-regeneration ability of the nucleus pulposus, a regenerative repair method remains necessary. In this study, a double-network hydrogel based on oxidized hyaluronic acid (OHA) and dopamine-modified gelatin (GelDA) was developed and combined with umbilical cord mesenchymal stem cells (UC-MSCs) for repairing IDD. The hydrogel exhibited excellent mechanical properties, biodegradability, and a gel-like structure mimicking that of the intervertebral disc, thereby promoting UC-MSC proliferation and differentiation. In addition, the hydrogel also exhibited antibacterial and self-healing properties. In a rat model of IDD, the OHA-GelDA@UC-MSCs hydrogel was shown to slow down the progression of disc degeneration.","PeriodicalId":516419,"journal":{"name":"临床骨科杂志","volume":"1 1","pages":"63-74"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147909223","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}
