Long implant for sacroiliac joint fusion

A system for the fusion of the sacroiliac joint, the system comprising:

• a guide pin having a length greater than the width of a patient's pelvis;
• a broach having a lumen for receiving the guide pin, the broach configured to form a rectilinear cavity in bone;
• and
• an implant having a rectilinear cross-section transverse to a longitudinal axis of the implant, the implant having a length greater than the width between a surface of the patient's right ilium and a surface of the patient's left ilium, the implant sized to fit through the rectilinear cavity formed by the broach.

A method for fusing both sacroiliac joints of a patient, the method comprising:

• inserting a guide pin through the first ilium and across the first SI-Joint, through the sacrum and above the S1 foramen, across the second SI-Joint, and through the second ilium;
• forming a first rectilinear cavity through the first ilium and the first SI-Joint;
• forming a second rectilinear cavity through the second ilium and the second SI-Joint, wherein the first rectilinear cavity and the second rectilinear cavity are aligned;
• and
• inserting an implant through the first cavity, across the first SI-Joint, through the sacrum, across the second SI-Joint, and through the second cavity, wherein the implant has a rectilinear cross-section transverse to a longitudinal axis of the implant that corresponds to the first rectilinear cavity and the second rectilinear cavity.

A method for fusing both sacroiliac joints of a patient, the method comprising:

• inserting a guide pin through the first ilium and across the first SI-Joint, through the sacrum between the S1 and S2 foramen, across the second SI-Joint, and through the second ilium;
• forming a first rectilinear cavity through the first ilium and the first SI-Joint;
• forming a second rectilinear cavity through the second ilium and the second SI-Joint, wherein the first rectilinear cavity and the second rectilinear cavity are aligned;
• and
• inserting an implant through the first cavity, across the first SI-Joint, through the sacrum, across the second SI-Joint, and through the second cavity.
