Three modes of failure in index sacroiliac joint (SIJ) fusion necessitating revision. (A) Violation of foramina causing radiculopathy. (B) Implant loosening about sacral aspect of implant. (C) Implant spanning the ligamentous portion of the SIJ.

(A) Lateral graphic of the sacroiliac joint showing the posterior/dorsal ligamentous portion of the joint and the anterior/ventral cartilaginous portion of the joint. (B) Oblique graphic highlighting the narrow ventral true cartilaginous portion of the joint that is the target for implant placement. Image courtesy of Visible Body.

Removal of loose implant with tubular retractor, screw removal set, and osteotomes.

Inlet (A), outlet (B), lateral (C) fluoroscopic views after navigation assisted placement of newly revised triangular implants with comparison to previously placed contralateral circular implants, highlighting the more ventral triangular implants. The ventral trajectory crosses the cartilaginous portion of the joint.

Axial and coronal postoperative computed tomography scans localized over the revised cephalad (A), middle (B), and caudal (C) navigated triangular implants, with previously placed contralateral circular implants. Red arrows: old implant tracts.
