Abstract
Background: Bony fusion is widely used operation technique in orthopedics and reconstructive surgery to fix skeletal damages and facilitate spinal fusion. Local autografts and allografts suffer from drawbacks like donor site morbidity and immune rejection or slow tissue-healing rates. In the current several years, novel developments in the scientific properties of material, selection of biologics, and surgical procedures have brought new breeds of solutions for improving the bone healing and fusion process.
Aim: This review aimed to discuss novel developments for bone grafting from technique, material and utilities of biologics in view of the limitations posed by customary form of bone grafting. This paper seeks to ensure that it has offered detail information on how these innovations are designing the future as it relates to bone repair and fusion.
Methods: The review of the article encompassed the classification of bone grafts and the traditional methods of grafting alongside the contemporary techniques such as minimally invasive surgery, 3D bio printing and robot assisted surgery. New forms of scaffolds, including synthetic composites, bioactive glasses and smart biomaterials were also compared based on their ability to integrate with host tissue and to induce osteogenic response. BMPs, MSCs, and gene therapies were analysed with the help of clinical trials, cases and experiments conducted on animals.
Results: The use of advanced techniques showed better success and lesser recovery time than the conventional procedures. Synthetic and composite anything indicated better interface bonding with the naked host bone and contributed to enhanced osteogenesis. There were large advantages in utilizing growth factors such as BMPs and MSC- based therapies on bone regeneration and fusion rate,in particular in challenging patient population including osteoporotic patients and those who might required bone grafting of large bone gaps.
Conclusion: Prospects for improvement of the bone grafting methods and materials seem impressive today, as well as they eliminate the drawbacks of the old constructive methods and allow the application of the bioactive personalized approach to the treatment of bone defects. Nonetheless, the current significance of these techniques raises the questions of cost, availability, and compliant implementation that need to be discussed to include these methods into the conventional treatment strategies.
