## Indications for use
The Patriot-SI Posterior Implant System is intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. When the Patriot-SI Posterior Implant System (i.e., an “in-line” or “intra-articular” device) is implanted, it must be used with a Spinal Simplicity Liberty-SI Lateral System device (i.e., a “transfixing” device) implanted across the same sacroiliac joint to create a hybrid SI joint fusion construct.
