Double-center observational study of minimally invasive sacroiliac joint fusion for sacroiliac joint dysfunction: one-year results.

ABSTRACT:

Background

For a substantial part of patients with chronic low back pain, the origin is located in the sacroiliac joint (SIJ). Minimally invasive sacroiliac joint fusion (MISJF) is increasingly being implemented as a treatment option in SIJ dysfunction. Despite remaining controversy, evidence continues to increase. This study evaluates the clinical results and safety of MISJF in a double-center consecutive case series in patients with SIJ dysfunction over a one-year observation period.

Methods

SIJ complaints were diagnosed after history taking, physical examination and least a 50% reduction of SIJ pain 30-60 min following image-guided injection. Primary outcome measures were patient reported outcome measurements (PROMs), consisting of Visual Analogue Scale (VAS) pain score and EuroQol 5-dimensions 3-levels (EQ-5D-3L). Patients' perspectives on the effects of surgery were collected through questionnaires. Secondary outcome measures were implant positioning and (serious) adverse events ((S)AE's).

Results

A total of 29 patients were included. In 44.8% of patients, SIJ dysfunction was of postpartum origin. The mean VAS-pain score improved from 7.83 (± 1.71) to 4.97 (± 2.63) postoperatively (p < 0.001). EQ-5D-3L score improved from 0.266 (± 0.129) to 0.499 (± 0.260) postoperatively (p < 0.001). Opioid consumption decreased from 44.8 to 24.1% postoperatively (p = 0.026). In 13.7% of patients, an (S)AE occurred.

Conclusion

MISJF appears to be an effective and safe procedure in this cohort. Statistically significant and clinically relevant improvements in pain and quality of life were observed one-year postoperatively. Future studies should focus on the long-term outcomes to further evaluate the safety and effectiveness of MISJF.

Project description:BackgroundThis report documents 1-year results of 250 patients enrolled in a prospective, multicenter study of a minimally invasive (MI) sacroiliac joint fusion (SIJF) system that uses decortication, graft placement, and joint fixation.MethodsThe cohort includes all patients enrolled in the EVoluSIon (EVSI) clinical study who had MI SIJF surgery and completed 1-year follow-up. Average age at baseline was 60.5 years, and 70.8% were female. Sacroiliac (SI) joint-related pain duration was ≥2 years in 56% of patients. Visual analog scale (VAS) SI joint pain, Oswestry Disability Index (ODI), quality of life, and opioid use were assessed preoperatively and at 1 year.ResultsAt 1 year, the mean VAS pain demonstrated a significant reduction of more than 43 points, from 76.4 at baseline to 33.0 (P < 0.0001), with 72.2% of patients attaining the minimal clinically important difference (MCID, ≥20-point improvement). Mean ODI scores also significantly improved from 54.4 at baseline to 30.5 at 1 year (P < 0.0001), with 62.5% of patients achieving the MCID (≥15-point improvement). Prior to surgery, 62.7% (126/201) of patients were taking opioids or other narcotics, but by 1 year postsurgery, only 26.9% (54/201) of patients reported using these medications, representing a significant 57.1% decrease in narcotic/opioid use (P < 0.0001). Fusion of the SI joint was seen in 68.7% of patients. Few procedural complications were reported. In all, there were 8 (8/250) serious procedure-related events, including 1 device malposition observed on the day of surgery that required replacing the superior screw with a shorter screw.ConclusionsAnalysis of patients treated with MI SIJF in the EVSI study demonstrated that the procedure can be performed safely and results in significant improvements in pain, quality of life, and opioid use at 1 year as well as causing fusion in the majority of patients.Level of evidence: 2Clinical relevanceMI SIJF differs from most procedures currently being performed in that it applies true orthopedic principles with decorticating, bone grafting, fusion, and placement of implants perpendicular to the joint for greatest stability. The 12-month data show improvement in functionality, reduction in pain, and, most notably, a reduction in narcotic usage, which is important considering the ongoing opioid epidemic.

Project description:BackgroundSacroiliac (SI) joint pain is an often overlooked cause of low back pain. SI joint arthrodesis has been reported to relieve pain and improve quality of life in patients suffering from degeneration or disruption of the SI joint who have failed non-surgical care. We report herein early results of a multicenter prospective single-arm cohort of patients with SI joint degeneration or disruption who underwent minimally invasive fusion using the iFuse Implant System®.MethodsThe safety cohort includes 94 subjects at 23 sites with chronic SI joint pain who met study eligibility criteria and underwent minimally invasive SI joint fusion with the iFuse Implant System® between August 2012 and September 2013. Subjects underwent structured assessments preoperatively, immediately postoperatively, and at 1, 3, and 6 months postoperatively, including SI joint and back pain visual analog scale (VAS), Oswestry Disability Index (ODI), Short Form-36 (SF-36), and EuroQoL-5D (EQ-5D). Patient satisfaction with surgery was assessed at 6 months. The effectiveness cohort includes the 32 subjects who have had 6-month follow-up to date.ResultsMean subject age was 51 years (n=94, safety cohort) and 66% of patients were women. Subjects were highly debilitated at baseline (mean VAS pain score 78, mean ODI score 54). Three implants were used in 80% of patients; two patients underwent staged bilateral implants. Twenty-three adverse events occurred within 1 month of surgery and 29 additional events occurred between 30 days and latest follow-up. Six adverse events were severe but none were device-related. Complete 6-month postoperative follow-up was available in 26 subjects. In the effectiveness cohort, mean (± standard deviation) SI joint pain improved from a baseline score of 76 (±16.2) to a 6-month score of 29.3 (±23.3, an improvement of 49 points, P<0.0001), mean ODI improved from 55.3 (±10.7) to 38.9 (±18.5, an improvement of 15.8 points, P<0.0001) and SF-36 PCS improved from 30.7 (±4.3) to 37.0 (±10.7, an improvement of 6.7 points, P=0.003). Ninety percent of subjects who were ambulatory at baseline regained full ambulation by month 6; median time to full ambulation was 30 days. Satisfaction with the procedure was high at 85%.ConclusionMinimally invasive SI joint fusion using the iFuse Implant System® is safe. Mid-term follow-up indicates a high rate of improvement in pain and function with high rates of patient satisfaction.
