Mechanical stimuli are converted into mechanotransduction signals through the perception of integrins, Piezo1 ion channels and bone cell networks. Activate downstream molecules are transduce through signal pathways such as Wnt/β-catenin, transforming growth factor β/bone morphogenetic protein-Smad, mitogen-activated protein kinase, protein kinase Hippo-Yes-associated protein/transcriptional coactivator with PDZ-binding motif, and phosphatidylinositol 3-kinase/ protein kinase B, so as to achieve the effects of promoting osteoblasts proliferation, accelerating endochondral ossification, regulating bone resorption and the like, thereby promoting the regeneration of new bone in the distraction area. The study of mechanotransduction signaling pathways in distraction osteogenesis is expected to optimize the mechanical parameters of distraction osteogenesis and provide targeted intervention strategies for accelerating new bone regeneration and mineralization in the distraction zone.

Although traditional open reduction and internal fixation has advantages such as direct reduction and simplicity of procedure, it has gradually fallen out of favor with clinical orthopedic doctors due to extensive soft tissue removal, excessive bleeding, tissue adhesion, and postoperative complications such as skin infection, fracture nonunion, and joint dysfunction. As medical technology continues to develop, minimally invasive surgery and precise diagnosis and treatment are gradually being introduced to orthopedic trauma. Guided by concepts such as \"minimally invasive treatment\", \"homeopathic repositioning of fractures\", and \"internal compression fixation\", many traction reduction devices, internal fixation devices, minimally invasive reduction techniques, and computer-aided navigation technologies have been widely used in the clinical treatment of TPFs. This has greatly helped to overcome the challenges of intraoperative reduction, secondary reduction loss, and postoperative functional impairment and effectively promoting the adoption of minimally invasive treatment techniques in the clinical treatment of TPFs.</p><p><strong>Conclusion: </strong>Minimally invasive treatment techniques have made significant progress in the clinical treatment of TPFs, particularly with regard to the reduction, and have demonstrated unique advantages. While relevant research results have received international recognition, there is still a need for orthopedic scholars to conduct real-world research to further explore the underlying principles and mechanisms of action.</p>","PeriodicalId":23979,"journal":{"name":"中国修复重建外科杂志","volume":"39 7","pages":"783-788"},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12279916/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144638218","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}
