Posterior approach to SI-joint fusion shows improvement after 6 months: study

Spine

A posterior approach to sacroiliac joint fusion led to improved pain scores over three to six months, a study found. 

Researchers examined outcomes in 69 patients who had a sacroiliac joint fusion with PainTEQ's LinQ implant, according to a June 21 news release from the devicemaker. After six months, one patient had a serious adverse event. A competitor's lateral approach had a 15.1 percent SAE incidence.

The study also found a significant improvement in visual analog scale pain scores, and patients reported a reduction in pain at the three, six and 12-month follow-ups.

"In our planned interim analysis of our multicenter study, the six-month outcome has unparalleled safety and non-inferior results to the lateral fusion approach, compared to what is published in peer-reviewed literature," Nomen Azeem, MD, one of the study's investigators, said in the release. "This represents the largest treatment arm for prospectively acquired sacroiliac joint fusion to date, across all approaches."
