1. An implant for fusing a sacroiliac joint, the implant comprising:
a monolithic body comprising a proximal end and a distal end separated by a body length, a first sidewall and a second sidewall separated by a body width, and a first face and a second face disposed in an opposing relationship to one another separated by a body height, wherein the body width is greater than the body height;
a first groove disposed within the first sidewall and a second groove disposed within the second sidewall, the first and the second grooves opening at the proximal end of the body, wherein the first and the second grooves extend along the first and the second sidewalls for at least a part of the body length;
a first plurality of anti-migration features disposed on the first face of the body, wherein apexes of the first plurality of anti-migration features are coplanar and are configured for abutting contact with a sacrum of the sacroiliac joint;
a second plurality of anti-migration features disposed on the second face of the body, wherein apexes of the second plurality of anti-migration features are coplanar and are configured for abutting contact with an ilium of the sacroiliac joint; and
a single graft window disposed within the body of the implant and opening to the first and the second faces, whereby the single graft window provides a passage through the body between the first and the second faces, wherein the single graft window is confined to an interior surface of the body whereby the single graft window does not open to the first sidewall or the second sidewall, and wherein no other apertures except for the single graft window are disposed on the first face or the second face of the implant;
wherein the first and the second grooves at least partially extend along the single graft window, and wherein a shortest distance between the interior surface of the body and an innermost surface of the first groove or the second groove defines a minimum wall thickness of the implant, wherein the minimum wall thickness is in a range of about 17% to about 20% of the body width.
