indicence of sacroiliac joint pain in failed back surgery

ABSTRACT

Sacroiliac joint can be a source of pain in cases of failed back surgery after spinal fusion. This can be due to a missed sacroiliac joint problem from before spinal surgery or it can be a new event secondary to violation of the sacroiliac joint during the graft technique or due to increased stress on the joint after spinal fusion. This study reviewed 30 patients with lumbosacral fusion, all presenting with persistent back pain and had surgery by the same technique using single midline incision for the spinal fusion and harvesting the graft. Fixation was done by pedicular screws and fusion using posterolateral autogenous bone graft. Seventeen patients had sacroiliac joint pain with positive therapeutic test using local injection of the sacroiliac joint. Ten patients had radiological changes on computerized tomography
