Disclosed is a bone cement composition which has a short downtime that is the time necessary for the composition to become ready for handling, and is therefore capable of achieving high work efficiency by shortening the time that is necessary before the handling of the bone cement composition is started. Also disclosed are a bone cement composition kit for obtaining a bone cement composition, and a method for producing a bone cement cured body.nThe bone cement composition is characterized by containing (meth)acrylate polymer large diameter particles having an average particle diameter of 10-60 μm, (meth)acrylate polymer small diameter particles having an average particle diameter of 0.1-2.0 μm, a (meth)acrylate monomer and a polymerization initiator. The bone cement composition is also characterized in that the content ratio of the (meth)acrylate polymer small diameter particles relative to the total amount of the (meth)acrylate polymer small diameter particles and the (meth)acrylate polymer large diameter particles is 5-30% by mass. |
