An implant for stabilizing a dysfunctional sacroiliac (SI) joint, comprising:
- a monolithic member and a bone stabilizing pin, said monolithic member configured and adapted to be advanced into said dysfunctional SI joint in said posterior trajectory,
- said monolithic member 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 of said monolithic member in any direction, said bridge section comprising a bridge proximal end and a bridge distal end,
- said first elongated section comprising a first open proximal end, a first open distal end, and a first internal lumen that extends from said first open proximal end to said first open distal end of said first elongated section, said first internal lumen comprising a first length from said first open proximal end to said first open distal end of said first elongated section, said first internal lumen sized and configured to receive said bone stabilizing pin therein,
- said first elongated section further comprising first internal threads, said first internal threads disposed in said first internal lumen and extending from said first open proximal end of said first elongated section,
- said first elongated section further comprising a first tapered region disposed on said first open distal end,
- said second elongated section comprising a second open proximal end, a second open distal end, and a second internal lumen that extends from said second open proximal end to said second open distal end of said second elongated section, said second internal lumen comprising a second length from said second open proximal end to said second open distal end of said second elongated section, said second internal lumen sized and configured to receive said bone stabilizing pin therein,
- said second elongated section further comprising second internal threads, said second internal threads disposed in said second internal lumen and extending from said second open proximal end of said second elongated section,
- said second elongated section further comprising a second tapered region disposed on said second open distal end,
- said first elongated section of said monolithic member further comprising a first plurality of fenestrations and said second elongated section of said monolithic member further comprising a second plurality of fenestrations,
- said bone stabilizing pin comprising a pin proximal end and a pin distal end, said bone stabilizing pin comprising a third length from said pin proximal end to said pin distal end, said third length of said bone stabilizing pin being greater than said first length of said first internal lumen of said first elongated section and said second length of said second internal lumen of said second elongated section,
- said pin proximal end comprising a threaded region adapted to engage and cooperate with said first internal threads of said first elongated section and said second internal threads of said second elongated section,
- said bone stabilizing pin configured and adapted to be advanced into said dysfunctional SI joint when said monolithic member is said advanced into said dysfunctional SI joint, said bone stabilizing pin is received in said first internal lumen of said first elongated section, and said bone stabilizing pin is advanced through said first internal lumen of said first elongated section,
- said bone stabilizing pin comprising a plurality of tabs, each of said plurality of tabs adapted to transition from a second collapsed configuration to a second outwardly projecting configuration when said bone stabilizing pin is advanced into said first internal lumen of said first elongated section.
