5 Claims

1. An implant for stabilizing a dysfunctional sacroiliac (SI) joint, the dysfunctional SI joint comprising a sacrum bone structure, an ilium bone structure and an intraarticular region between the sacrum and ilium bone structures, the implant comprising:

a hollow monolithic implant body configured and adapted to be advanced into said dysfunctional SI joint in a posterior trajectory,

said implant body comprising a first proximal end, a first distal end disposed opposite said first proximal end, and a first longitudinal axis,

said implant body further comprising a first elongated section, a second elongated section, and a bridge section, said bridge section disposed between and not extending beyond said first elongated section and said second elongated section in any direction,

said first elongated section configured to be advanced into said sacrum bone structure when said implant body is said advanced into said dysfunctional SI joint in said posterior trajectory,

said second elongated section configured to be advanced into said ilium bone structure when said implant body is said advanced into said dysfunctional SI joint in said posterior trajectory,

said bridge section configured to be advanced into said intraarticular region of said dysfunctional SI joint when said implant body is said advanced into said dysfunctional SI joint in said posterior trajectory,

said first elongated section comprising a first open proximal end, a second first closed distal end disposed opposite said first open proximal end, a first length from said first open proximal end to said second distal end, a first maximum thickness and a second longitudinal axis,

said first elongated section further comprising a first elongate lumen, said first elongate lumen extending from said first open proximal end to said second distal end of said first elongated section,

said first elongate lumen comprising a third longitudinal axis, said third longitudinal axis coincident with said second longitudinal axis of said first elongated section,

said first elongated section further comprising a first plurality of slots and a first tapered region disposed on said second distal end of said first elongated section, said first plurality of slots in communication with said first elongate lumen,

said second elongated section comprising a second open proximal end, a third distal end disposed opposite said second open proximal end, a second length from said second open proximal end to said third distal end, a second maximum thickness and a fourth longitudinal axis,

said second elongated section further comprising a second elongate lumen, said second elongate lumen extending from said second open proximal end to said third distal end,

said second elongate lumen comprising a fifth longitudinal axis, said fifth longitudinal axis coincident with said fourth longitudinal axis of said second elongated section,

said second elongated section further comprising a second plurality of slots and a second tapered region disposed on said third distal end of said second elongated section, said second plurality of slots in communication with said second elongate lumen,

said bridge section comprising a first internal cavity, a second proximal end, a fourth distal end disposed opposite said second proximal end, a third maximum thickness and a sixth longitudinal axis, said bridge section further comprising at least one elongated slot in communication with said first internal cavity,

said first elongate lumen of said first elongated section, said second elongate lumen of said second elongated section and said first internal cavity of said bridge section collectively forming a continuous implant body internal cavity,

said third maximum thickness of said bridge section being no greater than said first maximum thickness of said first elongated section and said second maximum thickness of said second elongated section,

said bridge section comprising a third tapered region disposed on said fourth distal end of said bridge section, said third tapered region comprising a gradually decreasing thickness along said sixth longitudinal axis of said bridge section, said sixth longitudinal axis of said bridge section being coincident with said first longitudinal axis of said implant body.
