Abstract

Orthopedic compositions are provided that include a homogeneous mixture of a biocompatible polymer and a bioactive particulate ceramic wherein the ceramic has an average particle size of not more than 500 nm are provided. The compositions may be used to form bone cement or various spinal implants, including spinal spacers, interbody fusion cages, bone plates and bone screws. Methods for stabilizing a spine, for correcting a bone defect, and for promoting fusion of adjacent vertebare are also provided.
