Anterior Extrusion of an Orthobiologic Sacroiliac Joint Implant in a Patient With Psoriatic Arthritis

More recently, multiple minimally invasive techniques for SIJ fusions have been developed, one of them being posterior insertion of an orthobiologic implant. Minimally invasive SIJ fusion has been shown to provide pain relief and decrease disability. Posterior implant insertion to partially fuse the SIJ carries minimal risk of complications, one of which is posterior dislodgment of the implant. However, anterior extrusion of the implant has not, to our knowledge, been described or reported.
