Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A method for joining together vertebral bodies, comprising: providing a tubular intervertebral implant having an open leading end communicating with a central aperture and a plurality of tabs carried on an outer surface; preparing a receiving bed in each of a pair of adjacent vertebral bodies separated by an intervertebral disk, the vertebral bodies cooperating to form a cylindrical kerf, the kerf forming a bone projection from each vertebral body; instantly fixing the vertebral bodies together by receiving the tubular implant within the kerf such that adjacent bone projections of associated vertebral bodies are received within the open leading end and into the central aperture and at least one of the tabs engages with one of the receiving beds to immobilize the implant within the cylindrical kerf.
Claim 2
Independent Claim
127 words
A method for joining together vertebral bodies, comprising: providing a tubular intervertebral implant having an open leading end communicating with a central aperture and a plurality of tabs carried on an outer surface; preparing a receiving bed in each of a pair of adjacent vertebral bodies separated by an intervertebral disk, the vertebral bodies cooperating to form a cylindrical kerf, the kerf forming a bone projection from each vertebral body; instantly fixing the vertebral bodies together by receiving the tubular implant within the kerf such that adjacent bone projections of associated vertebral bodies are received within the open leading end and into the central aperture and at least one of the tabs engages with one of the receiving beds to immobilize the implant within the cylindrical kerf.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein, over time, the instantly fixed vertebral bodies fuse together via arthrodesis.
Claim 4
Dependent Claim
32 words
The method according to claim 1 wherein the tubular body has an oblique outer surface, the oblique outer surface operative to impart distraction when receiving the tubular implant within the cylindrical kerf.
Claim 5
Dependent Claim
66 words
The method according to claim 1 wherein the tubular intervertebral implant has an open leading end, an open trailing end, and a central aperture, the open leading end, the open trailing end and the central aperture having a substantially uniform inner diameter operative to facilitate axial x-ray analysis of arthrodesis, wherein the implant is received within the kerf so as to facilitate x-ray analysis of arthrodesis.
Claim 6
Dependent Claim
16 words
The method of claim 4 wherein the tubular implant is positioned in a generally anterior/posterior direction.
Claim 7
Dependent Claim
25 words
The method of claim 1 wherein each bone projection comprises intact bone formed integrally from one of the vertebral bodies and configured to enhance osteogenesis.
Claim 8
Dependent Claim
28 words
The method of claim 1 wherein one of the tabs engages with the one receiving bed and another of the tabs engages with another of the receiving beds.
