A previously described method by Belanger for posterior fusion of the sacroiliac joint utilizing pedicular instrumentation is presented, suitable for cases with chronic pain. Two patients with nontraumatic disorders of the sacroiliac joint who have undergone successful arthrodesis by this technique are presented. One patient, with poliomyelitis sequels, had sacroiliac disruption secondary to mechanical overloading; the other, had degeneration of the sacroiliac joint. In both cases their fusion remained stable after 3 years follow-up.

The advantage of this technique, using iliac and S1 pedicular screws, is that the screws are relatively easy and rapid to insert. As they are connected to the rod a very stable fixation is achieve and this allows for a low-profil construct. This technique has reduced intra-operative blood loss and operative time.

This method of sacroiliac arthrodesis may be an attractive option for surgeons who are familiar with pedicle screws instrumentation techniques. It should be considered when contemplating sacroiliac arthrodesis in the rare instance of nontraumatic sacroiliac abnormality.
