Bioactive spinal implants and method of manufacture thereof

A spinal implant comprising:

• a body comprising a bioactive substance, further comprising:
• sides that are generally outwardly curved in transverse cross-section;
• a top surface and a bottom surface, both surfaces coupled with the sides, each one of the top surface and the bottom surface forming plural projections for enhancing interaction with a synthetic or natural vertebral body;
• a major recess formed in the body in communication with at least one of the top surface and the bottom surface, and
• a handling feature comprising at least one of a pair of elongated side recesses for receiving a manipulator and a front recess, the handling feature facilitating handling and insertion of the spinal implant into an intervertebral space.

A spinal implant comprising:

• a body comprising a bioactive substance, further comprising:
• an anterior side, a posterior side opposing the anterior side, and a pair of opposing sidewalls, said sidewalls being generally outwardly curved;
• a top surface and a bottom surface, both surfaces coupled with the sides, each one of the top surface and the bottom surface forming plural projections for enhancing interaction with a synthetic or natural vertebral body;
• at least one major recess formed in the body in communication with at least one of the top surface and the bottom surface;
• a handling feature comprising recesses in the top and bottom surfaces in communication with the anterior and posterior sides and at least one recess in the anterior or sidewalls, the handling feature facilitating handling and insertion of the spinal implant into an intervertebral space.

• at least one major recess formed in the body in communication with at least one of the top surface and the bottom surface;
• a handling feature comprising recesses in the top and bottom surfaces in communication with the anterior and posterior sides and at least one recess in the anterior or sidewalls for receiving an impaction tool, the handling feature facilitating handling and insertion of the spinal implant into an intervertebral space;
• and
• a fastening feature comprising at least one through-aperture in communication with the anterior side and either the top or bottom surface for insertion of fasteners that communicate with a synthetic or natural vertebral body.

A spinal implant comprising:

• a body comprising a bioactive substance, further comprising:
• an anterior side and a posterior side being parallel to and opposing the anterior side;
• a mesial side and a lateral side with one side being outwardly curved and the other being inwardly curved;
• a top surface and a bottom surface, each of the top and bottom surfaces including plural projections for enhancing interaction with a synthetic or natural vertebral body;
• a major recess formed in the body creating a longitudinal through-aperture in communication with the top and bottom surfaces, at least one minor recess formed in the body creating a latitudinal through-aperture in communication with the mesial and lateral sides, both through apertures in communication with each other;
• and
• a handling feature comprising a pair of anterior recesses formed at points where the anterior side communicates with the mesial and laterial sides, said recesses used for receiving a manipulator, a pair of posterior recess formed at points where the posterior side communicates with the mesial and lateral sides, and a front recess formed in the anterior side and a rear recess formed in the posterior side both communicating with a through-aperture, the handling feature facilitating handling and insertion of the spinal implant into an intervertebral space.
