Minimally invasive sacroiliac joint fusion.

What are the benefi ts of minimally invasive sacroiliac joint fusion? Frank M. Phillips, MD: Traditionally, fusion of the sacroiliac joint has involved open exposure of the joint with direct decortication of the articular surfaces, followed by bone grafting with supplemental fixation. Minimally invasive approaches to sacroiliac joint fusion aim to reduce the morbidity associated with open approaches by accessing the sacroiliac joint through a stab incision over the ileum, with implants then driven across the sacroiliac joint under fluoroscopy. The potential benefits of the minimally invasive approach include a shorter procedure with less disruption of the surrounding soft tissues and muscles, resulting in a shorter hospital stay and more rapid resumption of normal activities.
