Abstract: An osteogenic fusion device is provided that includes opposite end pieces with an integral central element. The end pieces are sized to maintain the height of an intervertebral disc space. The central element has a smaller diameter so that the fusion device forms an annular pocket around the central element. An osteogenic material is disposed within the annular pocket between the opposite end pieces. The osteogenic material is in direct contact with the adjacent vertebral bone.

The osteogenic fusion devices of the present invention may be combined with other fusion devices to form an implant system. Methods of promoting fusion bone growth in the space between adjacent vertebrae utilizing devices and systems of the invention are also described.

Abstract: Bone implantable devices and methodologies permit careful application of biologically active substances and management of bone growth processes. The device includes a body defining a carrier receiving area for locating adjacent bone. Carrier material is located in the carrier receiving area. Substance is delivered onto carrier material through a port. A pathway delivers substance from the carrier receiving area to the bone surface. The body may be in the form of a spinal fusion cage, facet fusion screw, artificial joint, bone fixation plate, interbody graft, IM nail, hip stem, or other bone-to-bone appliances or bone-to-device appliances. In use, carrier is installed in the carrier receiving area of the device. The device is then implanted adjacent a bone. The substance is applied to the carrier for subsequent delivery to the bone. By doping carrier material after device implantation, inadvertent contact of the substance with non-target bone is more easily eliminated.

Abstract: An intervertebral disc prosthesis having two cover plates and a prosthesis core that extends to the circumferential edge of the cover plates. The prosthesis core is mounted to the lower cover plate and forms a spherical sliding surface with the upper cover plate. The connection surface of the cover plates may be set back from the circumferential perimeter of the cover plates to provide an optimum size of the spherical sliding surface despite the set-back nature of the connection surface. The set-back is configured as an inclined transition surface that adjoins the connection surface to the circumferential edge. The set-back allows the intervertebral disc prosthesis to be fully inserted into the prepared disc space into the spared dorsolateral corners without protruding ventrally.
