Abstract
Prostheses and methods are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are configured to be advanced into dysfunctional SI joints in a posterior trajectory via surgically created pilot SI joint openings in the dysfunctional SI joint. The prostheses have first and second elongated edge sections, and a third elongated section disposed centrally between the first and second elongated sections. The prostheses also have a first bridge sections disposed between and connected to the first and third elongated sections and a second bridge section disposed between and connected to the second and third elongated sections.
Claims11
An apparatus for stabilizing a dysfunctional sacroiliac (SI) joint, said dysfunctional SI joint comprising a sacrum bone structure, an ilium bone structure and an intraarticular region disposed between said sacrum bone structure and said ilium bone structure, said apparatus comprising:
- a monolithic member configured and adapted to be advanced into said dysfunctional SI joint in a posterior trajectory, wherein said monolithic member transfixes said dysfunctional SI joint,
- said monolithic member comprising a first elongated section, a second elongated section and a third elongated section disposed between said first elongated section and said second elongated section,
- said monolithic member further comprising a first bridge section and a second bridge section, said first bridge section disposed between and connected to said first elongated section and said third elongated section, said second bridge section disposed between and connected to said second elongated section and said third elongated section,
- said first elongated section configured to be advanced into said sacrum bone structure when said monolithic member is said advanced into said dysfunctional SI joint in said posterior trajectory,
- said first elongated section comprising a first central longitudinal axis, a first open proximal end and a first closed distal end,
- said second elongated section configured to be advanced into said ilium bone structure of said dysfunctional SI joint when said monolithic member is said advanced into said dysfunctional SI joint in said posterior trajectory,
- said second elongated section comprising a second central longitudinal axis, a second open proximal end and a second closed distal end,
- said first elongated section and said second elongated section defining a monolithic member plane that intersects and is coincident with said first central longitudinal axis of said first elongated section and said second central longitudinal axis of said second elongated section,
- said third elongated section configured to be advanced into said intraarticular region of said dysfunctional SI joint when said first elongated section is said advanced into said sacrum bone structure and said second elongated section is said advanced into said ilium bone structure of said dysfunctional SI joint,
- said third elongated section comprising a third open proximal end and a third closed distal end,
- said third elongated section being offset from said first elongated section and said second elongated section in a first vertical direction, whereby said third elongated section extends beyond said first elongated section and said second elongated section in said first vertical direction.
