Injectable biomaterials have emerged as a promising solution, offering targeted delivery to defect sites while minimizing surgical trauma, thus enhancing healing efficiency and reducing the risk of adverse reactions. These materials conform to complex bone shapes, stabilizing irregular defects with minimum surgical intervention. Different materials can be combined to gain specific properties suitable for bone stabilization An ideal injectable materials should be a composite system leading to the scaffold formation directly at the defect site, supporting bone regeneration. These systems should be tailored to meet specific clinical needs, such as mechanical strength, biological activity, and degradation rate which matches the rate of new trabecular bone growth. Moreover, the gradual breakdown of the material helps prevent the weakening of surrounding bone. These properties should make them a versatile tool in bone tissue engineering.
