Abstract

Interbody fusion implants (10) that include a load bearing body (20) composed of a calcium phosphate material hardened around one or more structural reinforcing members (30) are provided. The reinforcing members (30) aid the load bearing body (20) in resisting bending forces and, in certain forms of the invention, aid in preventing expulsion of the implant after implantation. Methods for promoting fusion bone growth in the space between adjacent vertebrae and methods for making the inventive implants are also provided.
