Spinal fusion system including spinal fusion device and additional orthopedic hardware
A spinal fusion system including a spinal fusion device is disclosed for insertion between two adjacent vertebrae. Additional orthopedic hardware including at least one threaded member threadably engages the body of the device.
1 . A spinal fusion system comprising:
a spinal fusion device having a body for placement in between the external perimeters of spaced apart vertebral bodies, said body having at least in part a generally cylindrical sidewall with an exterior surface, said cylindrical side wall having a plurality of perforations therethrough, said exterior surface of said cylindrical sidewall being at least in part threaded; and
additional orthopedic hardware comprising at least one threaded member for threadably engaging said body.
2 . The spinal fusion system of claim 1 , wherein said at least one threaded member of said orthopedic hardware threadably engages at least one end of said body.
3 . The spinal fusion system of claim 2 , wherein said body has opposite ends, and further comprising an end member for cooperatively engaging at least one of said opposite ends of said body, said end member extending from said body when engaged to said body.
4 . The spinal fusion system of claim 3 , wherein said end member extending from said body comprises a portion of the length of said spinal device.
5 . The spinal fusion system of claim 3 , wherein at least one of said opposite ends is configured to threadably engage said end member.
6 . The spinal fusion system of claim 3 , wherein at least one of said opposite ends is at least in part open.
7 . The spinal fusion system of claim 6 , wherein said at least one end being at least in part open is adapted to threadably engage said end member.
8 . The spinal fusion system of claim 3 , wherein said end member is adapted to contact at least one of the spaced apart vertebral bodies.
9 . The spinal fusion system of claim 1 , wherein said sidewall includes a plurality of said openings therethrough.
10 . The spinal fusion system of claim 1 , wherein said body has a maximum diameter and a maximum length from one of said opposite ends to the other of said opposite ends, said maximum length being greater than said maximum diameter.
11 . The spinal fusion system of claim 1 , wherein said thread on said exterior surface is not continuous.
12 . The spinal fusion system of claim 1 , wherein said thread on said exterior surface has at least one interruption.
13 . The spinal fusion system of claim 1 , wherein said exterior surface is not threaded between spaced apart portions of said exterior surface that are threaded.
14 . The spinal fusion system of claim 1 , in combination with bone.
15 . The spinal fusion system of claim 14 , wherein said bone is loaded in said hollow interior of said spinal device.
16 . The spinal fusion system of claim 14 , wherein said bone is compressively loaded in said spinal device.
17 . The spinal fusion system of claim 1 , in combination with a fusion promoting substance other than bone.
18 . The spinal fusion system of claim 1 , wherein said spinal device comprises a fusion promoting substance.
19 . The spinal fusion system of claim 1 , wherein said spinal device is treated with a fusion promoting substance.
20 . The spinal fusion system of claim 1 , in combination with a source of osteogenesis.
21 . The spinal fusion system of claim 1 , wherein said spinal device comprises an implantation material that is stronger than bone.
22 . The spinal fusion system of claim 1 , wherein said spinal device comprises an implantation material that comprises a bone ingrowth material.
23 . The spinal fusion system of claim 1 , in combination with an implantation material that intrinsically participates in the growth of bone through said spinal device.
24 . The spinal fusion system of claim 1 , wherein said exterior surface is at least in part porous.
25 . The spinal fusion system of claim 1 , wherein said spinal device comprises an implantation material that is porous.
26 . The spinal fusion system of claim 1 , wherein said spinal device comprises an ASTM implant quality material.
27 . The spinal fusion system of claim 1 , wherein said spinal device is an artificial spinal implant.
28 . The spinal fusion system of claim 1 , wherein said spinal device is an interbody spinal implant.
