Abstract
A spinal fusion implant of non-bone construction to be introduced into an intervertebral disc space for the promotion of spinal fusion.
Claims25
A spinal fusion implant dimensioned to occupy an intervertebral space between a first vertebral body and a second vertebral body, comprising:
- a body portion having first and second contact surfaces, first and second lateral sides, a leading end and a trailing end;
- a first flange comprising a lip extending from said body at an interface between said first contact surface and said trailing end, said lip being generally centered between said first and second lateral sides and extending laterally to points short of said first and second sides;
- and
- a second flange comprising a pair of lips extending from said body at an interface between said second contact surface and said trailing end, said first lip of the pair extending laterally from said first lateral surface to a point short of the center of said trailing end and said second lip of the pair extending generally laterally from said second lateral side to a point short of center of said trailing end such that said first and second lips are separated by a void, wherein said void is complimentary in dimension to said lip of said first flange.
1 more element
A system for effectuating fusion between a first vertebral body and a second vertebral body, comprising:
- an implant including a body portion having first and second contact surfaces, first and second lateral sides, a leading end and a trailing end, a first flange comprising a lip extending away from said body portion at an interface between said first contact surface and said trailing end, said lip being generally centered between said first and second lateral sides and extending laterally to points short of said first and second sides, a second flange comprising a pair of lips extending away from said body portion at an interface between said second contact surface and said trailing end, said first lip extending laterally from said first lateral surface to a point short of the center of said trailing end and said second lip extending generally laterally from said second lateral side to a point short of the center of said trailing end such that said first and second lips are separated by a void, wherein said void is complimentary in dimension to said lip of said first flange;
- and
- a plurality of bone anchor elements.
