Abstract
A bone cement having a dry component including a large constituent and a small constituent. The small constituent fills a substantial volume of the interstitial spaces between the particles of the large constituent. Therefore, only a second or minor interstitial space is left remaining between the individual particles of the small constituent and the particles of the small constituent and the particles of the large constituent. Therefore, a reduced amount of a polymerizable component need be added to the dry component to form a bone cement. Such a bone cement formulation decreases the exothermic temperature of the bone cement and decreases the possibility of tissue necrosis in the implantation area.
