Abstract
Bone cement compositions and methods of making two-part bone cements. The methods comprise transferring premixed powder and a liquid component into a receptacle, and mixing the powder component and the liquid component to form a cement composition. The premixed powder component comprises an acrylic polymer and a radical initiator. The bone cement is loaded with from about 5% to about 6% gentamicin by weight of the powder component, and from about 4% to about 5% vancomycin by weight of the powder component. The methods include filling a mold cavity with the bone cement composition to form a temporary spacer implant. The bone cement compositions provide a viscosity profile sufficient for the bone cement composition to flow within the mold cavity for an elapsed working time period of greater than about 6 minutes from the start of mixing at approximately 23° C.
