SUMMARY
Currently there is only one paper in the literature evaluating a bilateral sacroiliac joint fusion procedure. That paper presented poor results. The purpose of this study is to present another posterior surgical procedure for a bilateral sacroiliac joint fusion. 15 patients having this procedure were retrospectively reviewed at an average 30.3 months post surgery. 13 patients also had lumbosacral pathology resulting in lumbosacral fusions at the time of the bilateral sacroiliac joint fusions. One complication consisted of a non-union of the sacroiliac joint requiring reoperation. There were no neurovascular injuries, infections or lasting morbidities. Visual Analog Scales improved to a statistically significant degree. Patient satisfaction rates were greater than 80%. These outcomes were much improved when compared to the previously published study. A bilateral sacroiliac joint fusion can be performed safely, with low complications, low re-operation rates, decreased pain scores and high patient satisfaction rates.
