| abstract |
Systems are described for stabilizing a dysfunctional sacroiliac (SI) joint of a subject. The systems include a tool assembly and a defect creation assembly, and a prosthesis. The tool assembly is adapted to create a pilot SI joint opening in the dysfunctional SI joint; portions of which being disposed in the sacrum and ilium bone structures. The prosthesis is sized and configured to be press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures. The system optionally includes an image capture apparatus adapted to capture images reflecting positions and/or orientations of the tool assembly when disposed in the subject's body. |
