providing a plate of appropriate length adapted to overlap at least a portion of two adjacent cervical vertebral bodies anteriorly, said plate having at least a first plate segment adapted to be attached to one of the adjacent vertebral bodies to be fused and a second plate segment adapted to be attached to another one of the adjacent vertebral bodies to be fused, the first and second plate segments being in moveable relationship to one another along a longitudinal axis of the plate, the first and second plate segments being configured to couple together in cooperative relationship;
inserting at least two bone screws through the second plate segment and into the other of the vertebral bodies adjacent the disc space to be fused; and
permitting movement of the first and second plate segments attached to the adjacent vertebral bodies relative to one another in a direction toward one another along the longitudinal axis of the plate and resisting movement of the first and second plate segments in a direction away from one another along the longitudinal axis of the plate.
5. The method of claim 1, wherein the permitting step includes the step of allowing movement of the first and second plate segments of the plate in response to movement of the adjacent vertebral bodies.
12. The method of claim 1, further comprising the step of providing a fastener to fasten together the first and second plate segments.
13. The method of claim 12, further comprising the steps of providing an instrument configured to cooperatively engage the fastener and at least a portion of at least one of the first and second plate segments, and utilizing the instrument to move the fastener and the first and second plate segments relative to one another along a mid-longitudinal axis of the plate.
14. The method of claim 13, wherein the utilizing step includes the sub-step of rotating the fastener at least in part with the instrument.
15. The method of claim 12, further comprising the step of tightening the fastener from a first position to a second position to resist movement of the first and second plate segments relative to each other in at least one direction.
16. The method of claim 15, wherein the tightening step includes resisting movement of the first and second plate segments relative to one another when the fastener is in the second position.
17. The method of claim 15, wherein the tightening step includes permitting movement of the first and second plate segments relative to one another when the fastener is in the second position.
18. The method of claim 17, wherein the wherein the tightening step includes limiting the movement of the first and second plate segments relative to one another to one direction along the longitudinal axis of the plate.
19. The method of claim 17, wherein the tightening step includes limiting the movement of the first and second plate segments relative to one another to sequential increments along the longitudinal axis of the plate.
20. The method of claim 15, wherein the tightening step includes tightening the fastener to cause the fastener to tighten to the first plate segment while permitting movement of the first and second plate segments relative to one another.
21. The method of claim 1, further comprising the step of adjusting the overall length of the plate by moving the first and second plate segments relative to each other.
22. The method of claim 1, wherein the providing step includes selecting at least one of the first and second plate segments from a group of plate segments of various lengths.
23. The method of claim 1, wherein the providing step includes selecting at least one of the first and second plate segments from a group of plate segments of various configurations.
24. The method of claim 1, wherein the providing step includes providing a plate having at least a third plate segment.
25. The method of claim 24, wherein the providing step includes selecting at least one of the first, second, and third plate segments from a group of plate segments of various lengths.
26. The method of claim 24, wherein the providing step includes selecting at least one of the first, second, and third plate segments from a plurality of plate segments of various configurations.
27. The method of claim 1, further comprising the step of locking at least one of the bone screws to the plate.
28. The method of claim 27, wherein the permitting step occurs prior to the locking step.
29. The method of claim 1, wherein the permitting step includes the sub-step of moving the first and second plate segments relative to one another after the step of inserting the bone screws.
30. The method of claim 1, wherein the permitting step includes the sub-step of moving the first and second plate segments relative to one another before the step of inserting the bone screws.
31. The method of claim 1, wherein the permitting step includes the sub-step of applying a compressive load to the adjacent vertebral bodies.
32. The method of claim 1, wherein the permitting step includes moving the first and second plate segments from a first position to a second position.
33. The method of claim 1, further comprising the step of combining the plate with an interbody spinal fusion implant.
34. The method of claim 33, wherein the implant comprises at least in part bone.
35. The method of claim 33, wherein the implant is an allograft interbody bone graft implant.
36. The method of claim 33, wherein the implant is an artificial implant.
37. The method of claim 1, further comprising the step of combining the plate with a fusion promoting substance.
38. The method of claim 37, wherein the fusion promoting substance is at least in part other than bone.
39. The method of claim 37, wherein the fusion promoting substance is at least in part bone.
40. The method of claim 37, wherein the fusion promoting substance is hydroxyapatite.
41. The method of claim 37, wherein the fusion promoting substance comprises bone morphogenetic protein.
42. The method of claim 37, wherein the fusion promoting substance comprises genes coding for the production of bone.
43. The method of claim 1, wherein the providing step further comprises the step of providing bone screws for engaging the plate to the cervical spine, wherein at least a portion of one of the plate and the bone screws is a bioresorbable material.
44. The method of claim 43, wherein the bioresorbable material is at least in part bone.
45. The method of claim 1, further comprising the step of combining the plate with a substance for inhibiting scar formation.
46. The method of claim 1, further comprising the step of combining the plate with an antimicrobial material.
47. The method of claim 1, further comprising the step of treating the plate with an antimicrobial material.
48. The method of claim 1, further comprising the step of electrifying at least one of the plate and the bone screws for purposes of stimulating bone growth and contributing to bone fusion.
49. The method of claim 12, further comprising the step of electrifying at least one of the plate, the fastener, and the bone screws for purposes of stimulating bone growth and contributing to bone fusion.
