Case:

A 49-year-old woman presented with low back pain after a work-related injury. She failed 5 months of conservative management and subsequently underwent minimally invasive (MI) left sacroiliac joint (SIJ) fusion with 3 triangular titanium implants. Four months postoperatively, she developed recurrence of symptoms and radiographic halo phenomenon about the implants. The cephalad and caudal implants were replaced with threaded self-tapping implants, and the middle implant was unable to be removed. At 7-year follow-up, the halo phenomenon had resolved.

Conclusion:

This is an unusual case of radiographic halo phenomenon formation after MI SIJ fusion and halo resolution after subsequent revision.
