Minimally invasive sacroiliac joint fusion: one-year outcomes in 18 patients.

Cummings J, Capobianco RA - Ann Surg Innov Res (2013)

Bottom Line: There were no intraoperative complications and one explant at three months for malposition.All patient-reported outcomes showed both clinically and statistically significant improvement at 12 months (p < 0.001 for each of the following): VAS improved by 6.6 points, ODI scores improved by -37.5 points.Patient satisfaction with outcomes was high at 95%; 89% said would have the same surgery again.MIS SI joint fusion using a series of triangular porous TPS coated titanium implants is a safe and effective procedure for patients with SI joint disorders who have failed conservative care.

ABSTRACT

Background: Sacroiliac joint (SI) pain is an often-overlooked cause of low back pain due, in part, to lack of specific findings on radiographs and symptoms mimicking other back-related disorders. We report our experience with minimally invasive (MIS) SI joint arthrodesis using a series of triangular, titanium plasma spray (TPS) coated implants in patients refractory to conservative care.

Methods: We report outcomes from 18 patients with 12 months of postoperative follow-up.Demographics, complications, and clinical outcomes using visual analog scale (VAS) for pain, Oswestry Disability Index (ODI) for back function and SF-12 for quality of life were collected preoperatively and at 3, 6 and 12 months post-operatively.

Results: Mean age was 64 years and 67% of patients were female. There were no intraoperative complications and one explant at three months for malposition.All patient-reported outcomes showed both clinically and statistically significant improvement at 12 months (p < 0.001 for each of the following): VAS improved by 6.6 points, ODI scores improved by -37.5 points. One year SF-12 physical and mental component (PCS, MCS) scores approximated population normal scores for both physical and mental functioning. Patient satisfaction with outcomes was high at 95%; 89% said would have the same surgery again.

Conclusions: MIS SI joint fusion using a series of triangular porous TPS coated titanium implants is a safe and effective procedure for patients with SI joint disorders who have failed conservative care.

Mentions: Open arthrodesis of the SI joint was commonly performed in the early 1900s. However, open SI joint fusion is less common now as it requires relatively large incisions, significant bone harvesting, and lengthy hospital stays; moreover, patients must avoid weight -bearing for several months postoperatively [10-13]. Minimally invasive SI joint fusion has become available with various devices. Recent reports of a minimally invasive arthrodesis system have shown promising outcomes [14,15]. The surgical procedure involves the placement of three triangular implants across the SI joint (Figure 1). Second site bone harvesting or graft is not required as the porous titanium plasma spray (TPS) coating on the implants results in biological fixation of the implant in bone. Herein we report safety and effectiveness outcomes of patients undergoing MIS SI joint fusion with a series of triangular titanium, porous TPS coated implants (iFuse Implant System, SI-BONE, Inc., San Jose, CA) in a single surgeon’s private practice.
