Displacement of the iliac wing in sacroiliac luxation usually occurs cranial and slightly dorsal to the sacrum. Like most other pelvic injuries, several other fractures or luxations must be present in other pelvic bones for the fragment to displace. Sacroiliac luxations can range from minimally to severely displaced, and the severity of the displacement often depends on the type and severity of the other pelvic fractures. Likewise, the remaining stability afforded by the sacroiliac joint may also depend on the integrity of the remainder of the pelvis.
