Spinal fusion implant

A bone implant having a fusible body useful in spine fusion procedures comprising:

• a cylindrical structure having a smooth circumferentially outwardly disposed outer wall, an first surface at a first end of said outwardly disposed outer wall and a second surface at a second end of said outwardly disposed outer wall, and wherein said first surface is angled with respect to said second surface, and wherein said first surface includes at least a first series of slots each slot of said series lying generally adjacent and spaced apart from each other, and having opposite parallel walls angled with respect to said first surface of said bone implant, and wherein said smooth circumferentially outwardly disposed outer wall has a minimum height between said first and said second surfaces as a posterior end of said implant and wherein said smooth circumferentially outwardly disposed outer wall has a maximum height between said first and said second surfaces an anterior end of said implant and wherein a transition from said smooth circumferentially outwardly disposed outer wall at said posterior end to at least one of said first and said second surfaces is rounded to facilitate insertion of said bone implant into an intervertebral disc space.

A bone implant having a fusible body and useful in spine fusion procedures comprising:

• a cylindrical structure having a smooth circumferentially outwardly disposed outer wall, an first surface at an first end of said outwardly disposed outer wall and a second surface at a second end of said outwardly disposed outer wall, and wherein at least a portion of at least one of said first surface and said second surface has an overall convex shape with respect to said outwardly disposed outer wall, said portion of at least one of said first surface and said second surface further has at least a first series of slots each slot of said series lying generally adjacent and spaced apart from each other and having opposite parallel walls angled with respect to said at least one of said first surface and said second surface.

An implant having a fusible body and useful in spine fusion procedures comprising a cylindrical structure having a circumferentially outwardly disposed surface between an first surface and a second surface, and wherein said circumferentially outwardly disposed surface has a maximum dimension extending between said first and said second surface at an anterior side of said cylindrical structure and a minimum dimension extending between said first surface and said lower surface at a posterior side of said cylindrical structure, to account for a natural lordosis in an intervertebral disc space between two adjacent vertebral bone plates, and wherein said first and said second surfaces are convex for complementing a natural biconcavity of said intervertebral disc space, and wherein at least one of said first and second surface has at least a first series of slots each slot of said series lying generally adjacent and spaced apart from each other, and having opposite parallel walls angled with respect to said at least one of said first and second surface of said bone implant.
