Abstract

A surgical implant system includes an implant and a fixation member for securing the implant to tissue. The implant and the fixation member together comprise a single monolithic structure. The implant includes an insertion instrument. The implant, the fixation member, and the insertion instrument together comprise a single monolithic structure and are constructed from a single material. The implant is monolithically connected to the fixation member at a first frangible connection and is monolithically connected to the insertion instrument at a second frangible connection. Each of the frangible connections can be broken when force is applied.

Claims (26)

1. A method comprising:

providing a surgical implant system including an implant, a bone screw for securing the implant to tissue, and an insertion instrument, wherein the implant is monolithically connected to the bone screw at a first frangible connection and the implant is monolithically connected to the insertion instrument at a second frangible connection, such that the implant, the bone screw, and the insertion instrument together comprise a single monolithic structure; and

packaging the surgical implant system in a single package.

2. The method of claim 1 , wherein the packaging step results in a sterile kit.

3. The method of claim 1 , further comprising the step of 3D printing the surgical implant system.

4. The method of claim 1 , wherein at least a portion of the implant is porous.

5. The method of claim 4 , wherein at least a portion of the implant has an interconnected porosity.

6. The method of claim 1 , wherein at least a portion of the implant is solid.

7. The method of claim 1 , wherein the surgical implant system includes both solid and porous portions.

8. The method of claim 7 , wherein the bone screw is solid.

9. The method of claim 7 , wherein the insertion instrument is solid.

10. The method of claim 7 , wherein at least a portion of the implant is porous.

11. The method of claim 1 , wherein the packaging step includes forming a blister package.

12. A method comprising:

providing a surgical implant system including an implant and a bone screw for securing the implant to tissue, wherein the implant is monolithically connected to the bone screw at a frangible connection such that the implant and the bone screw together comprise a single monolithic structure; and

packaging the surgical implant system in a single package.

13. The method of claim 12 , further comprising the step of 3D printing the surgical implant system.

14. The method of claim 12 , wherein a first portion of the surgical implant system is solid and a second portion of the surgical implant system is porous.

15. The method of claim 12 , wherein the packaging step includes forming a blister package.

16. The method of claim 12 , wherein the packaging step results in a sterile kit.

17. A method comprising:

providing a surgical implant system including an implant and an insertion instrument, wherein the implant includes a body that is monolithically and directly connected to the insertion instrument at a frangible connection such that the implant and the insertion instrument together comprise a single monolithic structure; and

packaging the surgical implant system in a single package.

18. The method of claim 17 , wherein the packaging step results in a sterile kit.

19. The method of claim 17 , further comprising the step of 3D printing the surgical implant system.

20. The method of claim 17 , wherein the packaging step includes forming a blister package.
