Beschreibung
Zusammenfassung:The invention has as its objects the provision of a bone cement composition, a bone cement composition kit for obtaining the bone cement composition, and a production method of a bone cement hardened material, which are short in doughing time that is a time required to become a state in which a good handling operation can be conducted, and have consequently capable of achieving a high working efficiency by shortening the time required before the handling operation is started. The bone cement composition of the invention contains large-diameter (meth)acrylate polymer particles having an average particle diameter of 10 to 60 µm, small-diameter (meth)acrylate polymer particles having an average particle diameter of 0.1 to 2.0 µm, a (meth)acrylate monomer and a polymerization initiator, wherein the content of the small-diameter (meth)acrylate polymer particles is 5 to 30% by mass based on the total mass of the small-diameter (meth)acrylate polymer particles and the large-diameter (meth)acrylate polymer particles.
