Device, Composition and Method for Prevention of Bone Fracture and Pain

Methods, apparatus, compositions for reinforcing bone structures are disclosed as well as a reinforced bone structure itself. By injecting a low viscosity polymeric solution into a trabecular bone region at least partly surrounded by cortical bone allowing it to cross-link in-situ, a non-degradable gel can effectively reinforce the region by retaining fluid in the constrained space within the cortical shell. Due to the low viscosity of the pre-cross-linked aqueous polymeric solution, the entire site could be filled effectively and consistently. Additionally, by injecting a low viscosity pre-cursor, the solution fills the natural intra-trabecular spaces without substantial alteration of the trabecular structure at the site.
