Abstract

An interbody implant can comprise a cage and a porous structure. The cage can comprise an anterior segment, a medial segment, a posterior segment and a lateral segment contiguously connected to each other to define an interior space. The porous structure can be located in the interior space and can be bounded by the cage. The porous structure can comprise opposed superior and inferior surfaces exposed through the cage, an internal cavity located in an interior of the porous structure, and a plurality of ports connecting the internal cavity to the superior and inferior surfaces. A superior-inferior stiffness of the interbody implant can be defined by the porous structure. The porous structure can be compressed within a patient by movement of the spine to biologically stimulate bone growth in vertebrae adjacent the interbody implant. The implant can be configured for lateral, anterior and posterior insertion at different spine levels.

Claims20

Dependent claims

An interbody implant comprising:

a first cage defining a first interior space;
a second cage defining a second interior space;
and
a monolithic porous structure bounded by the first cage and the second cage, the monolithic porous structure comprising:
a first panel located in the first interior space of the first cage, the first panel including a first surface exposed through the first cage, the first surface including a first plurality of pores defined by a first lattice structure;
a second panel located in the second interior space of the second cage, the second panel including a second surface exposed through the second cage, the second surface including a second plurality of pores defined by a second lattice structure;
and
a third panel defining an interior cavity able to receive bone-growth-promoting material through a plurality of openings,
wherein a plurality of ports connect the interior cavity within the third panel to the first and second plurality of pores in the first and second surfaces of the first and second panels, respectively, to distribute the bone-growth-promoting material within the interior cavity through the first and second plurality of pores while maintaining a stiffness for the monolithic porous structure that also permits compression of the monolithic porous structure.

6 more elements

An intervertebral implant, comprising:

a monolithic porous structure formed of a porous material having a plurality of openings in a plurality of exterior surfaces, the monolithic porous structure shaped to define:
an interior cavity able to receive and store bone-graft material;
a superior panel;
an inferior panel;
a middle panel separating the superior panel and the inferior panel to define the interior cavity;
and
a plurality of passages extending through the monolithic porous structure to intersect the interior cavity and distribute the bone-graft material within the interior cavity through the plurality of openings while maintaining a longitudinal stiffness for the monolithic porous structure that also permits compression of the monolithic porous structure;
a first cerclage cage surrounding the monolithic porous structure;
and
a second cerclage cage surrounding the monolithic porous structure such that the longitudinal stiffness of the intervertebral implant is defined by the monolithic porous structure.

7 more elements

An intervertebral implant for implantation with an insertion tool, the intervertebral implant comprising:

a monolithic porous structure formed of a porous material having a plurality of openings in a plurality of exterior surfaces, the monolithic porous structure shaped to define:
an interior cavity able to receive and store bone-graft material;
and
a plurality of longitudinal passages extending through the monolithic porous structure to intersect the interior cavity and distribute the bone-graft material within the interior cavity through the plurality of openings while maintaining a longitudinal stiffness for the monolithic porous structure that also permits compression of the monolithic porous structure;
a first cerclage cage surrounding the monolithic porous structure;
a second cerclage cage surrounding the monolithic porous structure and uncoupled from the first cerclage cage such that the longitudinal stiffness of the intervertebral implant is defined by the monolithic porous structure;
and
a socket able to receive the insertion tool, wherein the socket includes a first portion formed from a first segment of the first cerclage cage and a second portion formed from a second segment of the second cerclage cage opposite the first cerclage cage.
