Abstract

Bone fusion system, devices, guides, implant and methods for using the bone fusion system, devices, guides and implant are disclosed. The fusion system includes a first alignment guide, a second alignment guide, and an implant. The first alignment guide couples to an intermediate portion of the implant and the second alignment guide couples to a distal portion of the implant. The implant includes a body portion, a first extension portion extending away from a first end of the body portion, a second extension portion extending away from a posterior of the body portion, and a third extension portion extending away from a distal end of the body portion. Finally, methods for using the bone fusion system, devices, guide and implant are disclosed.

a knob; and

a shaft extending away from the knob, wherein the shaft comprises:

a first portion coupled to and extending away from a second end of the knob;

a second portion coupled to and extending away from the first portion, wherein the first portion includes a first diameter, the second portion includes a second diameter, and the first diameter is larger than the second diameter; and

at least one engagement member coupled to and extending away from the second portion;

wherein the at least one engagement member is threaded to engage threads in an engagement opening in the implant; and

a tissue protector engaging a second end of the body, wherein the tissue protectors comprise:

a handle portion;

a shaft portion coupled to and extends from the handle portion;

a tip at a second end of the shaft portion; and

a through hole extending through the handle portion and shaft portion along a longitudinal axis of the tissue protectors;

wherein the tissue protectors extend through the at least one hole of the alignment portion of the alignment guide.

7 . The fusion system of claim 6 , wherein the attachment portion comprises:

a through hole extending from a top surface of the attachment portion through to the bottom surface of the attachment portion, wherein the fixation member extends through the through hole; and

wherein the alignment portion comprises:

at least one hole extending through the alignment portion from a first end to a second end.

8 . The fusion system of claim 7 , wherein the at least one hole is two holes, and wherein the two holes at least partially overlap.

9 . The fusion system of claim 6 , wherein the body of the first alignment guide is positioned at a first angle relative to a longitudinal axis of the implant, wherein the body of the second alignment guide is positioned at a second angle relative to the longitudinal axis of the implant, and wherein the first angle is different than the second angle.

10 . The fusion system of claim 9 , wherein the implant comprises:

a body portion, comprising:

at least one first through hole;

a first engagement opening for receiving a portion of the fixation member of the first alignment guide;

a first alignment opening spaced diagonally from the first engagement opening, wherein the first alignment opening receives an alignment pin of the first alignment guide;

a second engagement opening for receiving a portion of the fixation member of the second alignment guide; and

a second alignment opening spaced diagonally from the second engagement opening, wherein the second alignment opening receives an alignment pin of the second alignment guide;

a first extension portion extending away from a first end of the body portion, wherein the first extension portion comprises:

at least one second through hole; and

a compression slot positioned near a first end of the implant;

wherein the at least one second through hole is positioned between the compression slot and the body portion;

a second extension portion extending away from a second end of the body portion, wherein the second extension portion comprises:

at least one third through hole extending through the implant; and

wherein the second extension portion extends distally from the body portion; and

a third extension portion extending posteriorly away from the second end of the body portion, wherein the third extension portion comprises:

at least one fourth through hole extending through the implant; and

wherein the third extension portion extends posteriorly away from the body member and second extension portion.

11 . The fusion system of claim 10 , further comprising:

a first fastener, wherein the first fastener engages the first alignment guide to position the first fastener relative to the implant; and

a second fastener, wherein the second fastener engages the second alignment guide to position the second fastener relative to the implant.

12 . An implant comprising:

a body portion;

a first extension portion extending away from a first end of the body portion;

a second extension portion extending away from a second end of the body portion; and

a third extension portion extending posteriorly away from the second end of the body portion.

13 . The implant of claim 12 , wherein the body portion comprises:

at least one first through hole;

a first engagement opening for receiving a portion of the fixation member of the first alignment guide; and

a first alignment opening spaced diagonally from the first engagement opening, wherein the first alignment opening receives an alignment pin of the first alignment guide.

14 . The implant of claim 13 , wherein the body portion further comprises:

a second engagement opening for receiving a portion of the fixation member of the second alignment guide; and
