Enhancing Bone Grafting Outcomes: A Comprehensive Review of Antibacterial Artificial Composite Bone Scaffolds

Bone defects and dysfunctions are prevalent among patients, resulting from various causes such as trauma, tumors, congenital malformations, inflammation, and infection. The demand for bone defect repair materials is second only to blood transfusions. Artificial bone composites offer numerous advantages for bone damage repair, including their availability, absence of rejection or immune reactions, high malleability, exceptional me-chanical strength, and outstanding biocompatibility. However, bacterial infections frequently occur during bone transplantation or on graft material structures, leading to severe complications such as osteomyelitis and os-teoporosis. Moreover, existing osteogenic materials alone are inadequate to address the challenges posed by traumatic infections, presenting a significant hurdle for clinicians in reconstructing infectious bone defects. Consequently, it is crucial to functionalize artificial bone composites to facilitate effective bone repair and re-generation. Notably, antibacterial capabilities play a critical role in preventing and treating infectious bone de-fects, and current research is focusing on the interface between artificial bone composites and antibacterial treatments. This article provides an extensive review of the current state of artificial composite bone scaffolds with antibacterial properties for infection prevention in bone grafting.
