    anchoring the distal end of the anchor body in an interior region of the sacrum before compressing the sacroiliac joint;

    advancing the elongated implant structure coaxially over the proximal portion of the anchor body;

    abutting a washer against an exterior surface of the ileum, the washer disposed coaxially over a proximal portion of the compressive implant; and
