Abstract
A hybrid spinal implant for performing an intervertebral fusion procedure can include a pair of spacers separated by an expandable container that are formed of a porous titanium scaffold material. A connecting rod can span longitudinally between the pair of spacers. The spacers can be formed of titanium or PEEK, with endplates that are formed of the porous titanium scaffold material. The endplates can be bioactive. Exposed surfaces of the porous titanium scaffold material can be coated in a snag-preventing substance. The expandable container can be formed of a mesh material.
Claims15
A hybrid spinal implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient, and for being located in a space between opposing vertebral end plates of the adjacent vertebral bodies, the hybrid spinal implant comprising:
- a first spacer comprising a first endplate contacting surface and a second endplate contacting surface, wherein the first endplate contacting surface and the second endplate contacting surface are disposed on opposite sides of the first spacer, and wherein the first spacer is configured so that the first endplate contacting surface is disposed to face a first vertebral endplate of the opposing vertebral endplates, and the second endplate contacting surface is disposed to face a second vertebral endplate of the opposing vertebral endplates when the hybrid spinal implant is implanted in the space between the opposing vertebral end plates;
- a second spacer;
- a connecting rod spanning longitudinally between the first spacer and the second spacer, wherein the connecting rod includes a container fill port;
- and
- a porous and expandable enclosed container comprising a mesh material and disposed longitudinally between the first spacer and the second spacer and disposed to receive a fill material from the container fill port;
- wherein at least one of the first spacer or the second spacer includes a spacer fill port configured as a passage for fill material to pass from an exterior of the respective first spacer or the second spacer and into the connecting rod;
- and
- wherein the connecting rod extends longitudinally through the expandable enclosed container in a direction parallel to the opposing vertebral end plates of the adjacent vertebral bodies when the hybrid spinal implant is located in the space between opposing vertebral end plates of the adjacent vertebral bodies;
- and
- wherein each of the first spacer and the second spacer comprises a porous titanium scaffold material.
A hybrid spinal implant for performing an intervertebral fusion with a first vertebral endplate of a first vertebral body and with a second vertebral endplate of a second vertebral body, wherein the first vertebral body and the second vertebral body are separated from one another by a disc space, and the first vertebral endplate and the second vertebral endplate face one another, the hybrid spinal implant comprising:
- a first spacer (FS) comprising a first FS endplate contacting surface and a second FS endplate contacting surface, wherein the first FS endplate contacting surface and the second FS endplate contacting surface oppose one another;
- a second spacer (SS) comprising a first SS endplate contacting surface and a second SS endplate contacting surface, wherein the first SS endplate contacting surface and the second SS endplate contacting surface oppose one another;
- a connecting rod that extends longitudinally between the first spacer and the second spacer;
- and
- an expandable container comprising a mesh material and is disposable in an expanded configuration;
- wherein the container is disposed circumferentially around a portion of the connecting rod that is disposed between the first spacer and the second spacer, and wherein the container is configured to contain a fill material in the expanded configuration;
- and
- wherein the implant is configured to be disposed in an implanted orientation wherein the first FS endplate contacting surface and the first SS endplate contacting surface are disposed for engagement with the first vertebral endplate, and the second FS endplate contacting surface and the second SS endplate contacting surface are disposed for engagement with the second vertebral endplate;
- and
- wherein each of the first spacer and the second spacer comprises a porous titanium scaffold material.
