In this article, some advancements in injectable polymers mainly in bone repair has been highlighted. They offer significant advantages like minimal invasiveness, conformability to irregular bone defects, and also bioactivity through the incorporation of growth factors. As discussed previously, their properties can also be tailored to mimic the porosity and mechanical strength of trabecular bone as a temporary scaffold. Regardless of these facts, the highly porous structure of trabecular bone makes it still very challenging to possess good mechanical strength in load bearing regions.
