Implant and method for posterior sacroiliac fusion
An implant and method for posterior sacroiliac fusion having a plate for placement across the posterior surface of the sacroiliac joint, a transverse pin to slide through the plate and transverse the joint as well as provide an aperture to receive bone graft, and a sacral screw to be inserted through the plate.
1. A method of fixation and fusion of a sacroiliac joint comprising an ilium, a sacrum, and a sacroiliac joint space, the method comprising:
decorticating of said sacroiliac joint;
broaching a first channel through said ilium, across said sacroiliac joint space, and into said sacrum, wherein said first channel is configured to receive a transverse pin of a sacroiliac joint implant;
providing bone growth inducing material within said sacroiliac joint space;
drilling a second channel into said sacrum, wherein said second channel is configured to receive a first sacrum screw of said sacroiliac joint implant, wherein the second channel is adjacent the first channel;
drilling a third channel into said sacrum, wherein said third channel is configured to receive a second sacrum screw of said sacroiliac joint implant, wherein the third channel is adjacent the first channel, and wherein the first channel is between the second channel and the third channel;
placing a plate of said sacroiliac joint implant across said sacroiliac joint space, said plate comprising a sacrum portion and an ilium portion;
inserting said transverse pin through said plate and through said first channel;
inserting said first sacrum screw through said plate and through said second channel; and
inserting said second sacrum screw through said plate and through said third channel.
2. The method of claim 1 , wherein said providing bone growth inducing material within said sacroiliac joint space is prior to placement of said sacroiliac joint implant.
3. The method of claim 1 , wherein said providing bone growth inducing material within said sacroiliac joint space is after placement of said sacroiliac joint implant.
4. The method of claim 1 , wherein a portion of said providing bone growth inducing material within said sacroiliac joint space is prior to placement of said sacroiliac joint implant and wherein a portion of providing bone growth inducing material within said sacroiliac joint space is after placement of said bone growth inducing material.
5. The method of claim 1 , providing at least a portion of said bone growth inducing material to said sacroiliac joint space through an aperture within said transverse pin.
6. The method of claim 1 , wherein placing said plate comprises placing said sacrum portion flush with said posterior surface of a sacrum of a patient.
7. The method of claim 1 , wherein placing said plate comprises placing said ilium portion flush with said posterior surface of an ilium of a patient.
8. The method of claim 1 , wherein an angle between a bone contacting surface of said sacrum portion and a bone contacting surface of said ilium portion is between 95 degrees and 175 degrees.
9. The method of claim 1 , wherein an angle between a bone contacting surface of said sacrum portion and a bone contacting surface of said ilium portion is adjustable.
10. The method of claim 1 , wherein an angle between said sacrum portion and said ilium portion is configured to match anatomy of a particular patient.
11. The method of claim 1 , further comprising:
drilling a third channel into said ilium, wherein said third channel is configured to receive an ilium screw of said sacroiliac joint implant; and
inserting said ilium screw through said plate and through said third channel.
12. A method of fixation and fusion of a sacroiliac joint comprising an
ilium, a sacrum, and a sacroiliac joint space, the method comprising:
decorticating of said sacroiliac joint;
broaching a first channel through said ilium, across said sacroiliac joint space, and into said sacrum, wherein said first channel is configured to receive a transverse pin of a sacroiliac joint implant;
providing bone growth inducing material within said sacroiliac joint space;
drilling a second channel into said sacrum, wherein said second channel is configured to receive a sacrum screw of said sacroiliac joint implant;
placing a plate of said sacroiliac joint implant across said sacroiliac joint space, said plate comprising a sacrum portion and an ilium portion;
inserting said transverse pin through said plate and through said first channel;
inserting said sacrum screw through said plate and through said second channel; and
inserting said sacrum screw within a receiving component of said transverse pin.
