Anterior Approach and Stabilization of the Disrupted Sacroiliac Joint

Pelvic fractures with disruption of the important weight-bearing sacroiliac area can lead to impaired gait due to malunion or pelvic obliquity, back or buttock pain arising from the sacroiliac joint, and permanent neurologic damage. In eight patients with sacroiliac joint dislocation, an anterior retrofascial approach and stapling of the sacroiliac joint was performed. Six of these patients maintained an anatomic reduction of the sacroiliac joint and their results were rated as excellent. Two of the eight patients had a slight loss of reduction and because of intermittent mild pain were rated as having fair results. In another eight patients, plate fixation of the anterior sacroiliac joint was done. New stabilization methods utilizing dynamic compression plates, reconstruction plates, and a new four-hole plate have been developed to provide more secure fixation of these unstable injuries.
