Bilateral crescent fracture-dislocation of the sacroiliac joint: a case-based discussion and review of literature.

Background: Crescent fractures are a subset of lateral compression injuries associated with high energy trauma and are rotationally unstable. These fractures are rare bilaterally, and we present one such rare case of a bilateral crescent fracture.

Case Description: A 56-year-old male presented with run-over injury and was diagnosed with bilateral crescent fracture-dislocation of the Sacroiliac joint. He was stabilized hemodynamically and then operated with iliosacral screws and reconstruction plates. The fracture united, and the patient is doing his daily activities without discomfort at follow up of 1 year after fracture fixation.

Conclusion: Bilateral pelvic crescent fractures are rare and need optimization and fixation for improved functional outcomes. It is necessary to evaluate associated injuries.
