Abstract
Interbody fusion implants that include a load bearing body composed of a calcium phosphate material hardened around one or more structural reinforcing members are provided. The reinforcing members aid the load bearing body in resisting bending forces and, in certain forms, 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.

32. An interbody fusion wedge-shaped implant, comprising:
- a biocompatible load bearing body, said body comprised of a synthetic calcium phosphate material hardened around at least one structural reinforcing member for resisting bending forces when implanted, said body sized and configured for engagement between two vertebrae and having a superior surface configured to contact one of said vertebrae, and an inferior surface configured to contact the other of said vertebrae, said structural reinforcing member disposed between said superior surface and said inferior surface and extending along a length of said body.

50. An interbody fusion implant, comprising:
- a biocompatible load bearing elliptical body, said body comprised of a synthetic calcium phosphate material hardened around at least one structural reinforcing member for resisting bending forces when implanted, said body sized and configured for engagement between two vertebrae and having a superior surface configured to contact one of said vertebrae, and an inferior surface configured to contact the other of said vertebrae, said structural reinforcing member disposed between said superior surface and said inferior surface and extending along a length of said body.

51. An interbody fusion implant, comprising:
- a) a biocompatible load bearing body, said body comprised of a hardened synthetic calcium phosphate material, said body sized and configured for engagement between two vertebrae and having a superior surface and an inferior surface; and
b) at least one structural reinforcing member for resisting expulsion after implantation, said structural reinforcing member at least partially embedded in said load bearing body and configured to contact adjacent vertebrae.
