Novel articles of manufacture based comprising lattices based on trabecular bone, having a plurality of plates and interconnecting rods. The trabecular bone-inspired lattice may be designed based on the general alignment of plates and rods found in trabecular bone, including anisotropic lattices having one or more predominant axes of mechanical strength. Lumbar fusion implants and other implants are provided having a trabecular bone inspired lattice in which bone graft material may be packed and providing a scaffold for bone fusion and growth. The implants may be based on bone structures having a predominant axis of mechanical strength and may be deployed in sites with the predominant axis of mechanical strength aligned with the primary axis of mechanical stress, such as in the the spine.

Medical implants and other articles of manufacture based on trabecular bone lattices

The invention comprises various materials and methods for the formation of bone within a patient using implanted bodies that are seeded with bone forming cells. The implants of the invention may comprise interlocking building blocks which allow for the formation of any desired structure. The geometry of the resulting bone structure can be tailored with great precision, and can be controllably integrated with native bone as desired. Advantageously, the methods result in the formation of functional, structured bone and avoid overgrowth, undergrowth, and the use of growth factors such as BMP-2.
