Biomechanical Stability of Primary and Revision Sacroiliac Joint Fusion Devices: A Cadaveric Study.

These results indicate that implantation of laterally placed triangular titanium implants significantly reduces the motion of a sacroiliac joint using either the primary and revision sized implants. No statistically significant differences were detected when comparing the efficacy of primary, 7.5-mm revision, or 10.75-mm revision implants.
