Abstract: Calcium phosphate-based formulation for bone filling, comprising at least one adjuvant giving adhesion properties, wherein the at least one adjuvant is selected from the saccharide head surfactant group. The bone cement is characterized by adhesive properties particularly advantageous facilitating the setting of the cement and offering a better containment of the bone-cement or bone-cement-prosthesis interface.

Abstract: The invention relates to a system for preparing a polymerized bone cement, including two components reacting with each other when they are mixed to form a solid polymer material. The first component may include a biocompatible acrylic polymer and an initiator capable of initiating a polymerization reaction. The second component may include a monomer capable of dissolving an acrylic polymer, a polymerization activator and a polymerization inhibitor, system in which the second component also includes a biocompatible acrylic polymer dissolved in said monomer, identical or different from the polymer of the first component with an average molar mass greater than 1,000,000 g/mol and a residual initiator content of less than 0.1% to form a gel with determined viscosity. Another object of the invention is a composition designed to constitute the second component of as system used to prepare such cement.
