1. A sacroiliac joint implant for non-transverse placement between articular surfaces of a sacroiliac joint to dispose a sacrum and an ilium in substantially immobilized relation, the implant comprising:
a distal end, a proximal end opposite the distal end, an axial bore extending distally from the proximal end, and a length extending between the distal end and the proximal end; a first perpendicular flange extending the length of the implant and including a first planar top surface; a second perpendicular flange opposite of and substantially parallel to the first perpendicular flange, the second perpendicular flange extending the length of the implant and including a second planar top surface; a first connecting member coupled to and extending substantially perpendicularly between the first perpendicular flange and the second perpendicular flange, the first connecting member extending at least the length of the implant and comprising:
a distal edge that slopes from a distal most ti to a distal end of the first perpendicular flange; andat least one passage that extends transversely through the first connecting member between the distal end and the proximal end, the at least one passage dimensioned to allow an elongate member to be received within the at least one passage to anchor the implant to the articular surfaces, wherein the second perpendicular flange further includes an anti-migration element at a proximal end of the second perpendicular flange, the anti-migration element including a tapering of the proximal end of the second perpendicular flange in order to resist movement of the implant within the articular surfaces. |
