Spinal implant system and method

1. An interbody implant comprising:

a body extending along a longitudinal axis between opposite first and second ends, the body including opposite first and second vertebral engaging surfaces each extending from the first end to the second end, the body defining only one groove extending along the longitudinal axis and only one groove extending transverse to the longitudinal axis, the groove extending along the longitudinal axis being a first groove and the groove extending transverse to the longitudinal axis being a second groove, the grooves each extending into the first vertebral engaging surface.

2. An interbody implant as recited in claim 1 , wherein the grooves do not extend through the second vertebral engaging surface.

3. An interbody implant as recited in claim 1 , wherein the second groove extends transverse to the first groove to intersect and communicate with the first groove.

4. An interbody implant as recited in claim 1 , wherein the body includes opposite anterior and posterior surfaces that each extend from the first end to the second end, the body including an opening extending through the anterior and posterior surfaces.

5. An interbody implant as recited in claim 4 , wherein the body is configured to be manipulated between a non-aligned orientation in which visualization of the opening is obstructed by a surface of the body that prevents radiographic visualization of the opening and an aligned orientation in which the surface is oriented to allow radiographic visualization of the opening.

6. An interbody implant as recited in claim 1 , wherein the body includes a hollow cavity between the first vertebral engaging surface and the second vertebral engaging surface.

7. An interbody implant as recited in claim 6 , wherein the body includes a plurality of spaced apart openings that each extend through the first groove, the openings each being in communication with the hollow cavity.

8. An interbody implant as recited in claim 6 , wherein the body includes a plurality of spaced apart openings that each extend through the second groove, the openings each being in communication with the hollow cavity.

9. An interbody implant as recited in claim 6 , wherein the body includes opposite anterior and posterior surfaces that each extend from the first end to the second end, the anterior surface defining a first opening and the posterior surface defining a second opening, the openings each being in communication with the hollow cavity.

10. An interbody implant as recited in claim 9 , wherein the body includes a plurality of spaced apart third openings that extend through the first groove, the third openings each being in communication with the hollow cavity.

11. An interbody implant as recited in claim 9 , wherein the body includes a plurality of spaced apart third openings that extend through the second groove, the third openings each being in communication with the hollow cavity.

12. An interbody implant comprising:

a body extending along a longitudinal axis between opposite first and second ends, the body including opposite first and second vertebral engaging surfaces each extending from the first end to the second end, the body defining only two grooves extending along the longitudinal axis and only two grooves extending transverse to the longitudinal axis, the grooves extending along the longitudinal axis being a first groove and a second groove, the grooves extending transverse to the longitudinal axis being a third groove and a fourth groove, the first and third grooves each extending into the first vertebral engaging surface, the second and fourth grooves each extending into the second vertebral engaging surface.

13. An interbody implant as recited in claim 12 , wherein:

the first and third grooves do not extend through the second vertebral engaging surface; and

the second and fourth grooves do not extend through the first vertebral engaging surface.

14. An interbody implant as recited in claim 12 , wherein:

the third groove extends transverse to the first groove to intersect and communicate with the first groove; and

the fourth groove extends transverse to the second groove to intersect and communicate with the second groove.

15. An interbody implant as recited in claim 12 , wherein the body includes opposite anterior and posterior surfaces that each extend from the first end to the second end, the body including an opening extending through the anterior and posterior surfaces.

16. An interbody implant as recited in claim 15 , wherein the body is configured to be manipulated between a non-aligned orientation in which visualization of the opening is obstructed by a surface of the body that prevents radiographic visualization of the opening and an aligned orientation in which the surface is oriented to allow radiographic visualization of the opening.

17. An interbody implant as recited in claim 12 , wherein the body includes a hollow cavity between the first vertebral engaging surface and the second vertebral engaging surface.

18. An interbody implant as recited in claim 17 , wherein the body includes opposite anterior and posterior surfaces that each extend from the first end to the second end, the anterior surface defining a first opening and the posterior surface defining a second opening, the openings each being in communication with the hollow cavity.

19. An interbody implant as recited in claim 18 , wherein:

the body includes a plurality of spaced apart third openings that extend through the first groove;

the body includes a plurality of spaced apart fourth openings that extend through the second groove;

the body includes a plurality of spaced apart fifth openings that extend through the third groove;

the body includes a plurality of spaced apart sixth openings that extend through the fourth groove; and

the third, fourth, fifth and sixth openings are each in communication with the hollow cavity.

20. An interbody implant comprising:

a body extending along a longitudinal axis between opposite first and second ends, the body including opposite first and second vertebral engaging surfaces each extending from the first end to the second end, the body defining only one groove extending along the longitudinal axis and only one groove extending transverse to the longitudinal axis, the groove extending along the longitudinal axis being a first groove and the groove extending transverse to the longitudinal axis being a second groove, the grooves each extending into the first vertebral engaging surface,

wherein the second groove extends transverse to the first groove to intersect and communicate with the first groove;

wherein the body includes a hollow cavity between the first vertebral engaging surface and the second vertebral engaging surface;

wherein the body includes opposite anterior and posterior surfaces that each extend from the first end to the second end, the anterior surface defining a first opening and the posterior surface defining a second opening, the openings each being in communication with the hollow cavity;

wherein the body includes a plurality of spaced apart third openings that extend through the first groove, the third openings each being in communication with the hollow cavity; and

wherein the body includes a plurality of spaced apart fourth openings that extend through the second groove, the fourth openings each being in communication with the hollow cavity.
