Abstract

A spinal implant for use with a surgical treatment comprises a plate including a surface that defines a first cavity and a second cavity. The first cavity is oriented to implant a multi-axial fastener with a sacrum. The second cavity is oriented to implant a fastener with an ala of a sacrum. Systems and methods of use are disclosed.

First claim

What is claimed is:

1 . A spinal implant comprising:
a plate including a surface that defines a first cavity oriented to implant a multi-axial fastener with a sacrum and a second cavity oriented to implant a fastener with an ala of the sacrum.

2 . A spinal implant as recited in claim 1 , wherein each of the cavities are configured for alignment with a pathway that communicates with a posterior mid-line surgical approach.

3 . A spinal implant as recited in claim 1 , wherein the first cavity is oriented to implant the multi-axial fastener with an S1 vertebra of the sacrum.

4 . A spinal implant as recited in claim 1 , wherein the surface comprises a first wall including the first cavity and a second wall including the second cavity, the first wall being disposed at an angle relative to the second wall.

5 . A spinal implant as recited in claim 4 , wherein the first wall includes an outer surface engageable with tissue of an S1 vertebra of the sacrum and the second wall includes an outer surface engageable with tissue of the ala.

6 . A spinal implant as recited in claim 1 , further comprising an insert disposable in at least one of the cavities.

7 . A spinal implant as recited in claim 1 , wherein the surface defining the first cavity is threaded for engagement with an insert defining an opening configured for disposal of the multi-axial fastener.

8 . A spinal implant as recited in claim 7 , wherein the insert comprises one of a plurality of inserts having alternately sized openings.

9 . A spinal implant as recited in claim 1 , further comprising an awl configured for disposal with the first cavity to provisionally fix placement of the plate.

10 . A spinal implant as recited in claim 1 , further comprising a layer engageable with the surface to fix the fastener with the plate,

11 . A spinal implant as recited in claim 1 , wherein the plate comprises visual indicia configured to provide configuration and/or dimension of the plate.

12 . A spinal implant as recited in claim 1 , wherein the surface includes a first wall thickness that includes the first cavity and a second wall thickness that includes the second cavity, the second wall thickness being greater than the first wall thickness.

13 . A spinal implant as recited in claim 1 , wherein the plate defines a longitudinal axis, the first cavity being aligned with the axis and the second cavity being offset from the axis.

14 . A spinal implant as recited in claim 1 , wherein the fastener comprises a nail.

15 . A spinal implant as recited in claim 1 , wherein the fastener comprises a nail including a threaded surface engageable with the surface.

16 . A spinal implant as recited in claim 1 , wherein the multi-axial fastener engages the fastener.

17 . A spinal implant comprising:
a plate including a first wall having an outer surface being engageable with at least an S1 vertebra of a sacrum and an inner surface that defines an opening oriented to implant a multi-axial screw with the S1 vertebra, and the plate further including a second wall having an outer surface being engageable with at least an ala of the sacrum and an inner surface that defines an opening oriented to implant a nail with the ala.

18 . A spinal implant as recited in claim 17 , wherein the first wall is disposed at an angle relative to the second wall.

19 . A spinal implant as recited in claim 17 , wherein the multi-axial fastener engages the nail.

20 . A method for treating a spine, the method comprising the steps of:
providing a plate including a surface that defines a first cavity and a second cavity; delivering the plate along a surgical pathway comprising a posterior mid-line surgical approach to a surgical site such that the first cavity is oriented with a sacrum and the second cavity is oriented with an ala of the sacrum; delivering a fastener along the surgical pathway and with the second cavity for fixation with the ala; and delivering a multi-axial fastener along the surgical pathway with the first cavity for implantation with the sacrum.
