Systems, apparatus and methods for stabilizing bone structures

A musculoskeletal stabilization system, comprising:

• a spine structure stabilization sub-system and a pelvic structure stabilization sub-system,
• said spine structure stabilization sub-system comprising a plurality of bone-engaging anchoring assemblies, and first and second elongate stabilizing rods,
• each of said plurality of bone-engaging anchoring assemblies adapted to engage vertebral bone structures of said subject's spine,
• said first and second elongate stabilizing rods adapted to be positioned on opposite sides of said subject's sagittal plane,
• said pelvic structure stabilization sub-system comprising first and second prosthesis systems,
• said first prosthesis system comprising a first prosthesis adapted to be inserted into a first sacroiliac (SI) joint of a subject,
• said second prosthesis system comprising a second prosthesis adapted to be inserted into a second SI joint of a subject,
• said first prosthesis and said second prosthesis each comprising first and second elongated partially cylindrical sections connected to a first bridge section,
• said first bridge section comprising first bridge section proximal and distal ends, said first bridge section distal end comprising a first tapered region configured and adapted to disrupt at least first articular cartilage and cortical bone,
• said first elongated partially cylindrical section comprising a first elongated partially cylindrical section proximal end, a first elongated partially cylindrical section distal end, and a first internal lumen that extends through said first elongated partially cylindrical section, said first internal lumen comprising first internal threads disposed on said first elongated partially cylindrical section proximal end,
• said second elongated partially cylindrical section comprising a second elongated partially cylindrical section proximal end, a second elongated partially cylindrical section distal end, and a second internal lumen that extends through said second elongated partially cylindrical section, said second internal lumen comprising second internal threads disposed on said second elongated partially cylindrical section proximal end,
• said first prosthesis system further comprising first spine structure stabilization sub-system engagement means adapted to engage at least said first internal threads of said first elongated partially cylindrical section of said first prosthesis and said spine structure stabilization sub-system,
• said second prosthesis system further comprising second spine structure stabilization sub-system engagement means adapted to engage at least said first internal threads of said first elongated partially cylindrical section of said second prosthesis and said spine structure stabilization sub-system.
