Abstract Comminuted fractures, characterized by multiple bone fragments, present significant challenges in orthopedic surgery. Effective treatment often requires augmentation techniques to enhance fixation stability and promote regeneration. This review explores the application of void filler materials, including autografts, allografts, polymethyl methacrylate (PMMA), synthetic substitutes such as calcium phosphate ceramics bioactive glass, managing comminuted fractures. Autografts are gold standard due their superior osteogenic potential but limited donor site morbidity availability. Allografts mitigate these issues face concerns regarding immunogenicity reduced biological activity. PMMA, widely used for structural augmentation, provides immediate suffers from thermal necrosis, polymer shrinkage, cytotoxic risks. Synthetic substitutes, cement offer promising alternatives promoting integration while reducing complications associated with traditional grafts. However, mechanical limitations artificial nature leave room improvement. The highlights recent advancements biomaterial modifications improve degradation rates, osteointegration, resilience, composite materials ion-doped bio ceramics. Despite innovations, a gap remains developing an ideal material that combines integrity bioactivity. Future research should focus on integrating elements load-bearing capabilities optimize patient outcomes fracture management.
