Abstract
A method of treating a sacroiliac joint and/or a region proximate the sacroiliac joint includes distracting and/or stabilizing a recess between a sacral wall of a sacrum and an ilial wall of an ilium, cutting a surface of the ilial wall using a cutting device, and positioning an implant having a first planar wall and a second planar wall opposite the first planar wall into the recess, such that the first planar wall of the implant is in contact with an uncut surface of the sacral wall, and the second planar wall is in contact with the cut surface of the ilial wall. The implant can be formed as a wedge-shape, a double-wedge shape, or a cuboid shape.

A method of treating a sacroiliac joint and/or a region proximate the sacroiliac joint, the method comprising:
- distracting a recess between a sacral wall of a sacrum and an ilial wall of an ilium;
- cutting a surface of the ilial wall using a cutting device;
- and
- positioning an implant having a first planar wall and a second planar wall opposite the first planar wall into the distracted recess, such that the first planar wall of the implant is in contact with an uncut surface of the sacral wall, and the second planar wall is in contact with the cut surface of the ilial wall.
An implant for treating a sacroiliac joint and/or a region proximate the sacroiliac joint;
- the implant comprising:
- a first planar wall;
- and
- a second planar wall opposite the first planar wall;
- wherein each of the first and second planar walls are defined by at least a first side edge and a second side edge;
- wherein the first side edge of the first planar wall is distanced from the first side edge of the second planar wall by a first separation distance, and the second side edge of the first planar wall is distanced from the second side edge of the second planar wall by a second separation distance;
- and
- wherein the first separation distance is smaller than the second separation distance;
- and
- wherein the implant is a double-wedge-shaped cuboid.
A guide tube for inserting an implant into a recess of a patient between an ilial wall and a sacral wall, the guide tube comprising:
- a first end;
- a second end opposite the first end;
- a wall extending from the first end to the second end, the wall forming a channel between the first end and the second end, the wall having a first and second flat surfaces formed on an outer surface of the wall extending from the first end to the second end, the first and second flat surfaces positioned opposite one another;
- and
- first and second tangs extending from the second end, the first and second tangs formed as flat extensions of the wall, each having a first edge extending distally from and parallel to the first flat surface of the wall, a distal tip, and a second tapered edge from the distal tip to the second flat surface of the wall.
A kit for treating a sacroiliac joint and/or a region proximate the sacroiliac joint using an implant, the kit comprising:
- a plurality of implants, each implant having a double-wedge-shaped cuboid shape;
- and
- at least one guide tube comprising:
- a first end;
- a second end opposite the first end;
- a wall extending from the first end to the second end, the wall forming a channel between the first end and the second end, the wall having a first and second flat surfaces formed on an outer surface of the wall extending from the first end to the second end, the first and second flat surfaces positioned opposite one another;
- and
- first and second tangs extending from the second end, the first and second tangs formed as flat extensions of the wall, each having a first edge extending distally from and parallel to the first flat surface of the wall, a distal tip, and a second tapered edge from the distal tip to the second flat surface of the wall.
