1. A method for facilitating stabilization of a selected one of a right sacroiliac joint and a left sacroiliac joint of a pelvis of a patient, the method comprising:
providing an incision in one of a right portion and a left portion of a back and/or buttocks of the patient corresponding to the selected one of the right sacroiliac joint and the left sacroiliac joint;
accessing a posterior portion of one of a right coxal bone and a left coxal bone of the patient corresponding to the selected one of the right sacroiliac joint and the left sacroiliac joint;
preparing a first insertion hole through a first portion of the one of the right coxal bone and the left coxal bone, and across at least a first portion of the selected one of the right sacroiliac joint and the left sacroiliac joint between the one of the right coxal bone and the left coxal bone and one of a right side and a left side of a sacrum corresponding to the selected one of the right sacroiliac joint and the left sacroiliac joint;
preparing a second insertion hole behind a second portion of the one of the right coxal bone and the left coxal bone, through the one of the right side and the left side of the sacrum, across at least a second portion of the selected one of the right sacroiliac joint and the left sacroiliac joint, and into the one of the right coxal bone and the left coxal bone;
preparing a third insertion hole through a third portion of the one of the right coxal bone and the left coxal bone, across at least a third portion of the selected one of the right sacroiliac joint and the left sacroiliac joint, and into the one of the right side and the left side of the sacrum;
inserting a first bone anchor through and into the first insertion hole to extend through most of the selected one of the right sacroiliac joint and the left sacroiliac joint;
inserting a second bone anchor through and into the second insertion hole to extend through the one of the right side and the left side of the sacrum, across the selected one of the right sacroiliac joint and the left sacroiliac joint, and into the one of the right coxal bone and the left coxal bone to interconnect the one of the right coxal bone and the left coxal bone and the sacrum;
inserting a third bone anchor through and into the third insertion hole to extend through the one of the right coxal bone and the left coxal bone, across the selected one of the right sacroiliac joint and the left sacroiliac joint, and into the one of the right side and the left side of the sacrum to interconnect the one of the right coxal bone and the left coxal bone, and the sacrum; and
forming a lattice construct by implantation of the first bone anchor, the second bone anchor, and the third bone anchor to constrain movement between the one of the right coxal bone and the left coxal bone, and the one of the right side and the left side of the sacrum to facilitate stabilization across the selected one of the right sacroiliac joint and the left sacroiliac joint;
wherein the first bone anchor, the second bone anchor, and the third bone anchor each include a first end, an opposite second end, and a mid-longitudinal axis extending through the first end and the second end, and planes extending along each of the mid-longitudinal axis in cranial-caudal directions intersect with one another within the pelvis of the patient after the implantation of the first bone anchor, the second bone anchor, and the third bone anchor; and
wherein, after insertion of the first bone anchor, the second bone anchor, and the third bone anchor, the plane of the second bone anchor and the plane of the third bone anchor intersect one another on a medial side of the first bone anchor.
