an instrument extending between opposite first and second ends and comprising an intermediate section therebetween; and at least one implant including a body extending between opposite proximal and distal ends, the proximal end engaging the intermediate section and the distal end engaging the second end, the body defining an outer surface and being disposed to space apart opposing articular surfaces of a sacro-iliac joint, wherein the body includes at least one agent and is engageable with the opposing articular surfaces and the outer surface is compliant to a configuration of the opposing articular surfaces such that the body facilitates relative movement of the opposing articular surfaces; wherein the body expands from a first, collapsed orientation having a first diameter to a second expanded orientation having a second diameter, the second diameter being 2 to 10 times greater than the first diameter, the body being pre-formed to have a non-uniform shape when the body is in the second orientation and no external force is applied to the outer surface. |
