Abstract
A surgical method for exposure of the sacroiliac joint using a posterior approach begins with a longitudinal incision over the posterior iliac crest, centered on the posterior iliac spine. Holes which will be used to repair the iliac osteotomy are made obliquely from the medial to lateral to cross the plane of exposure. A cut through the bone is made lateral to the drill holes and centered over the sacroiliac complex with the aid of fluoroscope or radiograph imaging. The medial part of the iliac crest is freed from the back of the sacrum and displaced medially for the sacroiliac joint complex to be inspected, debrided, or curettaged for fusion. The closure and subsequent healing are facilitated by the predrilled oblique holes. These are used to re-attach the medial iliac bone to the remaining lateral ilium.
