acroiliac joint fusion for low back pain attributed to sacroiliac joint is beneficial in a subset of patients. However, varied conservative treatments were measured in previous studies. Moreover, there are lack of well design and long-term follow-up studies.
The primary objective of this study was to determine whether sacroiliac joint fusion was superior to conservative treatment for patients with low back pain in pain and function.
In the current metaanalysis, the 18 studies included 1457 patients with chronic sacroiliitis, from which 841 patients underwent Non-surgical management & 616 patients underwent minimally invasive SI fusion. The mean age of pooled sample is 50 years. The follow up period ranged from 2 weeks to 72 months.
In our meta-analysis, there was significant decrease in pain scores in patient treated with minimally invasive sacroiliac joint fusion (P-value=0.000001).
The decrease reported in the included studies of VAS and ODI after MISJF is clinically relevant statistically significant.
In terms of pain reduction: all conservative treatment modalities showed statistically significant reduction of pain at the end of follow up except in local anesthetic injection (P-value=0.00001).
In terms of disability score (ODI, Oswestry Disability Index): all conservative treatment modalities showed statistically significant reduction of ODI score at the end of follow up .

Summary
114
There was a dramatic relief of pain in cases treated with joint fusion than those treated with conservative treatment.
Using EQ-5D time trade-off scale, there was improvement in patient quality of life on patient treated with joint fusion higher than in cases of conservative management, but was statistically insignificant (P-value=0.76).
We found that proportion of patients who were able to walk for distance more than one kilometer were higher in case treated with joint fusion, but it was statistically insignificant (P value= 0.17)
By month 24, we observed 39 severe adverse events after sacroiliac joint arthrodesis, including sacroiliac joint pain, postoperative gluteal hematoma, and postoperative nerve impingement.
With conservative treatment there were no reported complications except in one study.
In fusion group few complication reported mostly were : hematoma formation, piriformis syndrome, cellulitis, deep-soft tissue infection, Implant penetration, non-displaced fracture and persistent joint pain.
