For patients with chronic sacroiliac joint pain, minimally invasive SI joint arthrodesis with SI-Bone's iFuse Implant System was more effective in improving outcomes over two years compared with conservative management, according to a study in The Journal of Bone & Joint Surgery.
Four things to know:
1. Of 103 total subjects, 51 were assigned to conservative management and 52 were assigned to sacroiliac joint arthrodesis between 2013 and 2015.
2. At two years, average self-rated low back pain improved by 45 points after arthrodesis and 11 points after conservative management.
3. In the group that received the iFuse implant, the prevalence of opioid use decreased from 56 percent at baseline to 33 percent at two years, while no significant change was observed in the conserved management group.
4. The triangular titanium iFuse Implant System is intended for sacroiliac fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption and degenerative sacroiliitis.
