Sacroiliac luxation in small animals: treatment options

Abstract

The term sacroiliac luxation-fracture (SIL/F) denotes traumatic separation of the ilial wing from the sacrum. This injury typically results from a traumatic event (most commonly a road traffic accident) and consequently is often seen with concomitant pelvic and/or other orthopaedic injuries. When indicated, the method of choice for SIL/F repair is lag screw fixation, which can be achieved via open reduction and internal fixation or minimally invasive osteosynthesis. The prognosis is in part affected by proper orientation of the iliosacral screw and adequate screw purchase into the sacral body. While conservative management may yield good outcomes, pain associated with nerve damage as well as chronic instability of the SIL, along with concomitant orthopedic and soft tissue injuries, should be thoroughly considered when choosing this option.
