Abstract

A spinal implant system includes at least one interbody implant having a first member including a tissue engaging surface and at least one mating element. A second member includes a tissue engaging surface and at least one mating element. An intermediate member includes at least one mating element. An intra-operative surgical tool is connectable with at least one of the members to engage adjacent mating elements and fix the intermediate member with at least one of the first member and the second member. Implants, surgical instruments and methods are disclosed.

First claim

What is claimed is:

1 . A spinal implant system comprising:
at least one interbody implant comprising a first member including a tissue engaging surface and at least one mating element, a second member including a tissue engaging surface and at least one mating element and an intermediate member including at least one mating element; and an intra-operative surgical tool connectable with at least one of the members to engage adjacent mating elements and fix the intermediate member with at least one of the first member and the second member.

2 . A spinal implant system as recited in claim 1 , wherein the surgical tool is pre-sterilized.

3 . A spinal implant system as recited in claim 1 , wherein the surgical tool includes spaced surfaces that compress the first member and the second member into mating engagement with the intermediate member to fix the intermediate member with the first member and the second member.

4 . A spinal implant system as recited in claim 1 , wherein the surgical tool includes a first part defining a cavity configured for disposal of the first member and a second part defining a cavity configured for disposal of the second member such that the parts compress the members into mating engagement.

5 . A spinal implant system as recited in claim 4 , wherein the parts comprise a guide for member engagement.

6 . A spinal implant system as recited in claim 4 , wherein the parts align the first member and the second member with the intermediate member.

7 . A spinal implant system as recited in claim 1 , wherein the intermediate member includes a substrate body and the first member and the second member each include an endplate.

8 . A spinal implant system as recited in claim 1 , wherein the at least one mating elements of adjacent members comprise at least one pin and a mating receiving slot.

9 . A spinal implant system as recited in claim 1 , wherein at least one of the first member and the second member comprise a plurality of layers.

10 . A spinal implant system as recited in claim 1 , wherein at least one of the first member and the second member comprise a solid layer and a porous layer.

11 . A spinal implant system as recited in claim 1 , further comprising a plurality of alternate first members that are interchangeable with the intermediate member.

12 . A spinal implant system as recited in claim 11 , further comprising a plurality of alternate second members that are interchangeable with the intermediate member.

13 . A spinal implant system as recited in claim 1 , further comprising a plurality of alternate intermediate members that are interchangeable with the first member and the second member.

14 . A method for assembling a spinal implant, the method comprising the steps of:
determining one or more criteria of at least one interbody implant for an intervertebral space, the at least one interbody implant including a first member, a second member and an intermediate member; selecting a first member based on the one or more criteria; selecting a second member based on the one or more criteria; selecting an intermediate member based on the one or more criteria; and intra-operatively connecting a surgical tool with at least one of the members to engage adjacent members to fix the intermediate member with at least one of the first member and the second member.

15 . A method as recited in claim 14 , further comprising the step of providing a plurality of alternate first members having at least one alternate dimension and are interchangeable with the intermediate member, and the step of selecting a first member includes selecting the first member from the plurality of alternate first members based on the one or more criteria.

16 . A method as recited in claim 15 , further comprising the step of providing a plurality of alternate intermediate members having at least one alternate dimension and are interchangeable with the first member and the second member, and the step of selecting an intermediate member includes selecting the intermediate member from the plurality of alternate intermediate members based on the one or more criteria.

17 . A method as recited in claim 14 , wherein the step of intra-operatively connecting a surgical tool includes compressing the first member and the second member into mating engagement with the intermediate member.

18 . A method as recited in claim 14 , wherein the step of intra-operatively connecting a surgical tool includes aligning the first member and the second member with the intermediate member.

19 . A method as recited in claim 14 , wherein the first member and the second member comprise printed osseointegrative titanium endplates.

20 . A spinal implant system comprising:
at least one interbody implant comprising a plurality of alternate first members each including a tissue engaging surface and at least one mating element; a plurality of alternate second members each including a tissue engaging surface and at least one mating element; an intermediate member including at least one mating element; and an intra-operative surgical tool connectable with at least one of the members to engage adjacent mating elements and fix the intermediate member with at least one of the first member and the second member, wherein the plurality of first members and the plurality of second members are interchangeable with the intermediate member.
